Sugar composition and transcriptome analysis in developing ‘Fengtang’ plum (Prunus salicina Lindl.) reveal candidate genes regulating sugar accumulation

Sweetness is an important attribute of fruit quality, which directly affects consumers' preference for fresh fruit and is mostly determined by carbohydrate composition. ‘Fengtang’ plum (Prunus salicina Lindl.) is recognized for its high soluble sugar content, but the sugar composition and the molecular mechanisms underlying sugar overproduction are not fully understood. In this work, the sugar components were analyzed using gas chromatography-mass spectrometry combined with transcription profiles from RNA-sequencing and Quantitative Real-time PCR during fruit development. The target metabolic group showed that sucrose was the dominant sugar component in mature fruit, followed by glucose, fructose, and sorbitol. Based on the transcriptome data and qRT-PCR validation, we identified 12 key structural genes that significantly responded to corresponding component accumulation: sucrose synthase (PsSUS4), sucrose phosphate synthase (PsSPS2), neutral invertase (PsNINV1/3/4), phosphoglucomutase (PsPGM1), UTP-glucose-1-phosphate uridylyl transferase (PsUGP1/2), hexose kinase (PsHXK1/3), sugar transport protein (PsSTP1), and Sugars Will Eventually be Exported Transporter (PsSWEET4). In which PsSUS4 and PsSPS2, whose encoding proteins immediately catalyze sucrose synthesis, were selected to be silenced using the virus-induced gene silencing technology. Silencing of PsSUS4 or PsSPS2 resulted in decreased sucrose content by 27.6% and 8%, respectively, compared with the control, verifying their important roles in sucrose accumulation. Subsequently, sugar metabolism networks in this high-sugar plum were constructed with 12 key structural genes, 72 putative transcription factors, and 4 major sugar components. These results might facilitate a better understanding of the molecular mechanisms of sugar accumulation in ‘Fengtang’ plum and provide a framework for future fruit quality improvement.

Food Preferences of Primary School Students in Yazd, Iran: A Cross-Sectional Study

Background: Studies have shown that children’s food preferences play a main role in the formation of long-term eating habits and nutritional patterns in their future lives. This study aimed to investigate food preferences of primary students in Yazd, Iran. Methods: This cross-sectional study was conducted on 420 primary school students of Yazd, both male and female, using two-stage sampling method. The data collection tool was a self-administered questionnaire including demographic variables and food preferences checklist. The data were entered in SPSS 23 software and analyzed by Mann-Whitney U test and Kruskal-Wallis test. The significance level of the tests was considered as P-value < 0.05. Results: Starchy food category with the mean score of 3.70±0.44 was reported as the highest food preference and protein category (3.17±0.69) was reported as the lowest food preference among food categories in students. Gender, economic status, and body mass index (BMI) were related to students’ food preferences (P < 0.05). The median score of food preference for vegetables, fruits, and proteins in girls was higher than boys (P < 0.05), and for starchy food, fast foods, snacks, and fats was higher for boys than for girls (P < 0.01). The mean score of starchy food preference in students with lean and normal BMI was higher than students in overweight and obese group (P= 0.01). Conclusion: Starchy food and protein categories were reported as the highest and lowest food preferences among primary school students, respectively. It seems necessary to pay special attention to increase the awareness of students as well as their parents and primary schools principals about healthy foods in childhood and healthy food environments.

Simulated extreme climate event alters a plant-frugivore mutualism

Anthropogenic climate change is contributing to an increase in the frequency of extreme weather events. These extreme events may affect interactions in mutualisms that provide key ecosystem functions, especially when the event is rare for a given system and participants are differentially affected. The tropical hardwood hammocks of Key Largo, Florida, USA are inhabited by a highly specialized endangered rodent, the Key Largo woodrat (Neotoma floridana smalli), which may be an important seed disperser of many native fleshy-fruited plant species. Other potential mammalian dispersers are generalist omnivores, northern raccoons (Procyon lotor) and Virginia opossums (Didelphis virginiana), that are less selective. We sought to demonstrate that extreme climate events could alter seed dispersal mutualisms by differentially affecting fruit preference of potential dispersers. We designed a replicated cafeteria-style experiment across the entire range of the Key Largo woodrat with fruit from sixteen native plant species and simulated an extreme climate event by exposing half of the fruits to sub-freezing temperatures. Freezing temperatures are rare in this tropical environment, but increased frequencies of these types of extreme events are predicted with climate change. Using camera traps, we monitored the removal of fruit and seeds by woodrats and the generalist consumers, predicting that changes in fruit quality resulting from exposure to sub-freezing temperatures would reduce preference by the more specialized woodrat relative to its generalist consumers. Indeed, exposure to subfreezing temperatures decreased the probability of fruit and seed removal by woodrats while generalist consumers preferentially removed more of the fruits and seeds exposed to sub-freezing temperatures. These data provide evidence that extreme climate events may affect species preferences for food asymmetrically, which may shift the dynamics of seed dispersal mutualisms. Over time, increasing frequencies of extreme weather events could indirectly affect communities and ecosystem services by shifting interactions between organisms.

Untangling Biocultural and Socioeconomical Drivers of African Plum Tree (Dacryodes edulis) Local Nomenclature Along a Rural-Urban Gradient in Central Cameroon

In Cameroon, the African plum tree (Dacryodes edulis [G. Don] H. J. Lam) is widely cultivated for its fruits, which contribute significantly to household food security and economy. In order to analyze the links between the social and ecological systems that result in the remarkable fruit diversity, we focused on how the important varietal diversity of African plums was perceived and named by tree owners. We conducted semi‑structured interviews in Center-Cameroon with 142 people belonging to the Beti ethnic group, in urban (Yaoundé), peri-urban and rural areas, and analyzed the data qualitatively and quantitatively. Along this urbanization gradient linking production to consumption regions, 158 different translated names were recorded. Most names (80%) were cited once, but some names based on fruit size and taste were common across the gradient. Although the highest total number of names was recorded in the rural site, many different names were also found along the urban–rural gradient. We did not detect difference in the number of named African plums between respondents with different characteristics. The local classification of African plums among the Beti was structured predominantly according to morphological and organoleptic criteria, but also to symbolic and practical criteria. African plums’ names were based on people’s fruit preferences, that favor large, oily, and blue to black fruits, and disregard pink-colored watery plums. This study is an entry point to explore the rising trade and thus ongoing domestication of the African plum tree from an often neglected perspective, that of local nomenclature.

Analysis of Determinants of Food Preferences in a Polish Population-Based Sample of Primary School Adolescents: Diet and Activity of Youth during COVID-19 (DAY-19) Study.

For the choices of food products, food preferences are crucial, as they influence the intake of nutrients and the resultant quality of diet, but in Poland, no studies of food preferences were conducted during the COVID-19 pandemic on a population of young adolescents. The aim of this study was to analyze the determinants of food preferences in a Polish population-based sample of primary school adolescents as part of the Diet and Activity of Youth during COVID-19 (DAY-19) Study. The DAY-19 Study focused on a national sample of a population of primary school adolescents who were recruited based on cluster sampling of participants from counties and schools, yielding a sample of 5039 individuals. Their food preferences were assessed using the Food Preference Questionnaire (FPQ), and they were compared in subgroups stratified by (1) gender: male and female; (2) age: younger (10-13 years) and older (14-16 years); (3) place of residence: urban and rural; (4) Body Mass Index (BMI): underweight, normal body weight, and overweight/obese (assessed based on Polish growth reference values); and (5) physical activity level: low and moderate (assessed using the International Physical Activity Questionnaire for children aged 10-13 (IPAQ-C) and adolescents aged 14-16 (IPAQ-A)). In the population of adolescents, no statistically significant differences in food preferences between subgroups stratified by gender were observed (p > 0.05). For boys, none of the studied factors (age, place of residence, BMI, physical activity level) was statistically significant determinant of food preferences (p < 0.05), while for girls, all of them were statistically significant determinants (p > 0.05). All the assessed factors (age, place of residence, BMI, physical activity level) in girls were associated with preferences for snacks, and older girls, those from a rural environment, those who were underweight and overweight/obese, as well as those having a low physical activity level declared a higher preference for snacks than younger ones (p = 0.0429), those from an urban environment (p = 0.0484), those of a normal body weight (p = 0.0091), and those having a moderate physical activity level (p = 0.0083). Similarly, girls from rural environments declared a higher preference for starches than those from urban environments (p = 0.0103), and girls having a low physical activity level declared a higher preference for fruit than those having a moderate physical activity level (p = 0.0376). Taking this into account, the population of girls, in particular, needs dedicated educational actions to support proper nutritional habits. Additionally, older age, living in a rural environment, being underweight and overweight/obese, and having a low physical activity level may be indicated as factors predisposing one to food preferences potentially promoting unhealthy dietary habits.

Effectiveness of a Behavior-and Age-Specific Nutrition Education Intervention to Promote Nutrition Knowledge and Preference for Fruits and Vegetables among Elementary School Children

ABSTRACT Background Lack of nutrition knowledge, low preference for fruits and vegetables (F&V), and underdeveloped taste are recognized as modifiable influencers of children’s F&V intake. Purpose To assess the effectiveness of a behavior-and age-specific nutrition education intervention to improve nutrition knowledge and preference for F&V among elementary school children. Methods In a quasi-experimental pre-and posttest assessment designed study, a six-week nutrition education intervention (including class-based nutrition education, hands-on activities, cooking demonstrations, and tasting) was implemented at four elementary schools. Nutrition knowledge and preference for F&V were evaluated at baseline and after the intervention. Wilcoxon signed-rank test was carried out to examine the differences between baseline and post-assessment. Results A total of 115 children (3rd- 5th grade) completed both baseline and post-assessment. After the intervention, participants showed a significant improvement in nutrition knowledge (mean [± sd] change score: 7.6 ± 3.7, P < .001). A significant improvement in F&V preference (Ps < .001) was found among the participants after the intervention. Discussion An age-and behavior-focused nutrition education intervention can improve children’s nutrition knowledge and F&V preference. Translation to Health Education Practice: This nutrition education curriculum can be implemented for the child population (age-specific groups) by adapting cultural priorities in nutrition lessons and cooking recipes.

Why We Should Look at Dinner Plates: Diet Changes in Cancer Patients

Malnutrition is often underestimated in the context of cancer therapy: the dietary trends initiated by patients after diagnosis are usually neither known to nor evaluated by the medical staff. Here, we propose a combined screening instrument evaluating malnutrition and dietary trends. The validated screening tool NRS-2002 was combined with a four-item questionnaire assessing whether (1) patients preferred certain foods, (2) avoided certain foods, (3) used dietary supplements or followed a special diet since the time of cancer diagnosis. The screening tool was routinely used by cancer patients in the daily practice of three oncological departments. The presented analysis was performed retrospectively and anonymized. Overall, 102 cancer patients undergoing systemic therapy (CP), 97 undergoing radiation therapy (RP), and 36 head-neck cancer patients (HNP) were screened. The CP cohort showed a higher rate of malnutrition (50.00%) than the HNP (28.13%) or RP (26.80%) cohort. Overall, diet changes were observed in 33.63% of all patients. Avoiding meat, stimulants, or hard and edgy food was often mentioned in free text answers, while patients reported a preference for fruit and vegetables. Nutritional supplements were used by 28.76% of the patients. While dietary changes were common, only 6.64% of the patients mentioned adhering to a specific cancer diet. Malnutrition is still underestimated nowadays. Diet trends, especially avoiding certain foods, are common in cancer patients, while adhering to a specific cancer diet is an exception. Diet trends should be assessed and addressed to avoid or aggravate malnutrition.

Bird preferences for fruit size, but not color, vary in accordance with fruit traits along a tropical elevational gradient.

Birds constitute one of the most important seed dispersal agents globally, especially in the tropics. The feeding preferences of frugivorous birds are, therefore, potentially of great ecological importance. A number of laboratory-based and observational studies have attempted to ascertain the preferences of certain bird species for certain fruit traits. However, little attention has been paid to community-wide preferences of frugivorous birds and the impact this may have on fruit traits on a broader scale. Here, we used artificial fruits of different colors and sizes to investigate community-wide fruit trait preferences of birds at three sites along an elevational gradient in Papua New Guinea. We recorded attack rates on artificial fruits as visible impressions made by a bird's beak during a feeding attempt. We also measured the colors and sizes of real fruits at each site, and the gape widths of frugivorous birds, allowing for comparisons between bird feeding preferences and bird and fruit traits. Regardless of elevation, red and purple fruits were universally preferred to green and attacked at similar rates to one another, despite strong elevational patterns in real fruit color. However, elevation had a significant effect on fruit size preferences. A weak, non-significant preference for large fruits was recorded at 700 m, while medium fruits were strongly preferred at 1700 m and small fruits at 2700 m. These patterns mirror those of both real fruit size and frugivorous bird gape width along the gradient, suggesting the potential for selective pressure of birds on fruit size at different elevations.

The spirit of the fruit: contextual and transituational motives for consumption

PurposeThis research aims to reach meaningful insights into fruit consumption motives. The study articulates contextual motives observed through inherent fruit characteristics (i.e. attributes and benefits) with personal motives that transcend the situation (i.e. emotions and cultural values).Design/methodology/approachThis qualitative study used the focus group technique comprising eight groups of eight to 10 subjects (n = 94). The participants were frequent fresh-fruit consumers.FindingsThe analysis differentiates contextual motives from transituational ones. Older participants are motivated by taking care of health matters. They value fruit as an expression of their determination to take action and care for others. Younger participants are motivated by the experience of pleasure. Fruits have a hedonic value related to joy, being refreshing and tasteful.Practical implicationsResults serve marketers and decision-makers to better target motivations for fruit consumption enhancement. These motivations could be implemented by communicating specific fruit attributes that respond to short-term needs. In the long run, marketers could create fruit consumption campaigns that respond to deeper consumer values.Social implicationsDesigning fruit consumption campaigns aligned with individuals' motives could effectively strengthen the adoption of a healthy lifestyle. This study is helpful from the aspect of a public-policy approach expected to improve public health.Originality/valueConsumers' fruit preference transcends tangible product characteristics to motives aligned with their goals, emotions and human values. This path merges two approaches: contextual motivations and the Means-end chain model. The first approach recognises short-term observable product characteristics, whereas the latter works on long-term values.

Characterizing the use, preferences, and perceptions of flavors in cigars in pregnant women

Background Flavors contribute to the appeal of tobacco products, but less is known about flavors in cigar products. The current study is the first to focus on characterizing the use and perceptions of flavors in cigar products among pregnant women. Methods Pregnant women (N = 124) reported their use, preferences (liking, attractiveness, smoothness, interest), perceptions of harm (general, pregnancy-specific, fetal), and postpartum intention to use eight flavor categories (menthol/mint, spices, fruit, chocolate, alcohol, other beverages, candy/sweet, tobacco). We utilized correspondence analysis of contingency tables to investigate clustering of preferences and perceptions of flavors across the sample, and examined how preferences and perceptions of flavors may differ based on history of cigar use (none vs. lifetime vs. prenatal). Results Overall, 37% reported never trying cigars, 51% reported lifetime use, and 12% reported prenatal use. Fruit (37%), tobacco (36%), and alcohol (14%) were the most common cigar flavors participants reported ever trying. Correspondence analysis revealed clustering in preferences for alcohol, fruit, and candy flavors compared to other flavors, and revealed lower intentions to use menthol/mint and tobacco flavors compared to other flavors. Participants who reported prenatal cigar use also reported more positive perceptions and greater intentions to use (1) spice and alcohol flavors compared to those who reported lifetime use (ps < .05); and (2) spice, alcohol, fruit, and tobacco cigar flavors compared to participants reporting never using cigars (ps < .04). Conclusions Regulations to restrict the availability of flavors, especially fruit, spice, and alcohol, may reduce the appeal and use of cigar products in pregnant women.

Various macro and micro-morphological characters of three sex types of highland papaya (Vasconcellea pubescens) in Java, Indonesia

Abstract. Laily AN, Daryono BS, Purwantoro A, Purnomo. 2022. Various macro and micro-morphological characters of three sex types of highland papaya (Vasconcellea pubescens) in Java, Indonesia. Biodiversitas 23: 6238-6246. Highland papaya (Vasconcellea pubescens A.DC.), locally called karika, is a fruit plant successfully introduced to Java, Indonesia. V. pubescens plays an essential role as it contains various substances that can be used as ingredients in the food, pharmaceutical, and cosmetic industries. This plant is dioecious and monoecious as it contains three sex types, namely female, male, and monoecious. It grew from seed and began to bear fruit two years after sowing. The consumer preference for fruit is produced from female plants because female plants produce fruit faster, more abundantly, and with maximum fruit size under suitable environmental conditions. Sex differentiation is important for farmers to ensure the growth of female plants. Therefore, this research aimed to investigate the variation in macro and micro-morphological characters. The results showed that leaf and flower differ in macromorphological characters among the three sex types. Similarly, there were considerable differences in the trichomes of female and monoecious plants based on micro-morphological characteristics. There was no significant difference in seed shape between those. Seeds from female and monoecious plants differed in macro and micro-morphological characters. Macro and micro-morphological characters might have potential applications in early sex determination in V. pubescens. Macro and micro-morphological characters have many potential applications in early sex determination in V. pubescens.

Seasonal Distribution and Food Preference of the Peach Fly, Bactrocera zonata (Saunders) on Different Types of Citrus Fruit Trees in Baghdad Governorate

Al-Jassani, R.F. and A.H. Abou Rgheef. 2023. Seasonal Distribution and Food Preference of the Peach Fly, Bactrocera zonata (Saunders) on Different Types of Citrus Fruit Trees in Baghdad Governorate. Arab Journal of Plant Protection, 41(2): 93-97. https://doi.org/10.22268/AJPP-41.2.093097 The study was conducted in an orchard in Baghdad city to monitor infestation rate and movement of Bactrocera zonata in infested fruits during different periods. Results obtained showed that the seasonal distribution of the peach fruit fly B. zonata was proportional to the presence of the fruits and their maturity stage in the orchard. Apricots infestation occurred in May and June, peach in June and July, yellow figs in July and August, mango in August and September, mandarin in October and November, oranges in November and December, and sour orange in December. The results of the study demonstrated that the peach fruit fly varied in its preference and infestation of the different citrus species fruits, based on fruits infestation rates and the average larvae number per fruit. Mandarin fruits were the most preferred types of citrus by B. zonata, followed by orange fruits, grapefruit, sindhi, sweet lemon, and sour orange. In contrast, the sour lemon fruits were not infested. The seasonal distribution of fruit types is important and can be used in the design of preventive control strategies to protect the various fruits from insect’s infestation. Keywords: Peach fruit fly, seasonal distribution, Baghdad, mandarin, sour orange

Consumer Fruit Preferences: The Role of Nutrition Knowledge in Fruit Purchase and Consumption

Consumer Fruit Preferences: The Role of Nutrition Knowledge in Fruit Purchase and Consumption

Can chemical attributes replace sensory evaluation in consumer preference for papaya fruits?

The expansion of the papaya crop depends on cultivars with superior characteristics and human acceptance of the product. Thus, the objective was to study the sensory aspect and the main chemical characteristics of the fruit in 23 papaya genotypes cultivated in the north of the state of Espírito Santo and to evaluate if any chemical characteristic can be used to replace the evaluation by the hedonic scale. At 12 months after planting, fruit samples were evaluated for soluble solids content, titratable acidity, SS/TA ratio and a nine-point structured hedonic scale. The samples submitted to the hedonic scale were represented in codes and evaluated according to the experimental design in randomized blocks, totaling 12 treatments with 15 replications in the first experiment and 11 treatments and 21 replications in the second experiment. The data obtained were submitted to analysis of variance and Tukey's test at 5% probability. The means of the four characteristics, in the two experiments, were submitted to Pearson's linear correlation analysis. There was marked variability between the genotypes by the hedonic scale in the two experiments, highlighting the hybrids CR1 x São Mateus and JS12 x SSAM as the most accepted by the consumer.

The volatilome response of fast-melting peaches to short low oxygen stress

Fast-melting peaches have a shelf life of only 3–4 d due to their rapid softening, and this poses a problem in marketing and consumer acceptability. A postharvest 22 h treatment at 20 °C of low oxygen (<1%) or 2 µl L−1 1-methylcyclopropene (1-MCP) was applied to delay softening. 1-MCP was ineffective, but the anaerobic stress delayed softening as expressed by texture measurements, ethylene levels, and chlorophyll index values. Taste panels showed a preference for untreated fruit of the same firmness as treated fruit, probably due to off-flavors volatiles evaporation. Nevertheless, consumer acceptance of treated fruit was high after 3 d at 20 °C and 4 d of cold storage, while control fruit was too soft to be sampled. Volatile compounds were analyzed on control and low oxygen-treated fruit following treatment and 48 h later. Forty-eight compounds were identified, and thirty-nine significantly differed among all four conditions. Eleven volatile compounds associated with anaerobic conditions increased in the low oxygen treatment after 72 h. However, the low oxygen treatment did not affect most ripening-related peach fruit volatiles, primarily lactones. It is hypothesized that these compounds diminished the perception of off-flavors associated with the anaerobic volatiles. This simple low oxygen treatment demonstrates promising results in delaying softening and extending the market life of fast-ripening peaches.

Oviposition behaviour in Drosophila melanogaster: Genetic and behavioural decoupling between oviposition acceptance and preference for natural fruits.

In phytophagous insects, oviposition behaviour is an important component of habitat selection and, given the multiplicity of genetic and environmental factors affecting its expression, is defined as a complex character resulting from the sum of interdependent traits. Here, we study two components of egg-laying behaviour: oviposition acceptance (OA) and oviposition preference (OP) in Drosophila melanogaster using three natural fruits as resources (grape, tomato and orange) by means of no-choice and two-choice experiments, respectively. This experimental design allowed us to show that the results obtained in two-choice assays (OP) cannot be accounted for by those resulting from no-choice assays (OA). Since the genomes of all lines used are completely sequenced, we perform a genome-wide association study to identify and characterize the genetic underpinnings of these oviposition behaviour traits. The analyses revealed different candidate genes affecting natural genetic variation of both OA and OP traits. Moreover, our results suggest behavioural and genetic decoupling between OA and OP and that egg-laying behaviour is plastic and context-dependent. Such independence in the genetic architectures of OA and OP variation may influence different aspects of oviposition behaviour, including plasticity, canalization, host shift and maintenance of genetic variability, which contributes to the adoption of adaptive strategies during habitat selection.

Understanding Blood versus Blond Orange Consumption: A Cross-Cultural Study in Four Countries.

Understanding consumer perceptions and attitudes to specific fruit is key information for not only increasing fruit consumption, but also for marketing reasons. It may also give clues to breeders to set quality objectives. This study explores different aspects that help to explain blood vs. blond orange consumption: availability and consumption habit, satisfaction attributes, facilitators and consumption barriers, consumption contexts, expectations and purchase intention. The study was conducted in China, Mexico, Spain and Italy, where citrus fruit consumers were invited to respond an online questionnaire. Our results revealed Italy as the country with the highest availability and consumption of blood oranges, followed by China, Mexico and Spain. “Liking” and “healthy properties” were the most important reasons for consumption irrespectively of orange type, but certain differences among countries were detected in secondary reasons. In all the countries, “juicy” was the most relevant attribute for consumer satisfaction, followed by flavour/taste attributes. “Aromatic” and “unfibrous” were substantial requirements for Italians and Chinese, while Spaniards attached importance to the blood oranges colour. Regarding consumption contexts, “eat with salt or chilly powder” was specific for Mexico, while “to improve health”, “as a gift” or “at a restaurant” were contexts mainly cited in China. Despite taste preferences for other fruit being the main consumption barrier in all the countries for both orange types, the relevance of other barriers depended on culture and orange type. Mexican participants seemed to take a more neophobic attitude to blood oranges, while “inconvenient” was reported as a barrier for consuming blond ones in Spain and China. We conclude that blond and blood oranges can co-exist on markets at a high consumption rate, as in Italy. Specific interventions are needed in other countries because consumer attitudes to oranges, mainly blood ones, depend on culture.

Foraging Strategies of Invasive Macaca fascicularis may Promote Plant Invasion in Mauritius

The effectiveness of seed dispersal by frugivorous primates may vary between seasons and plant species, depending on foraging strategies. We investigated how foraging strategies of an invasive frugivorous primate (the long-tailed macaque, Macaca fascicularis) affect seed dispersal effectiveness (SDE) between native and invasive plants in Mauritius’ native remnant forests. By collecting behavioural data on a group of partially habituated macaques via scan sampling from December 2019 until December 2020 (mean 19.2 ± SD 7.3 hours per month), we investigated seasonal patterns in diet, home range, and fruit availability to identify foraging strategies and determine fruit preference. We simultaneously assessed SDE for invasive vs native plants by quantifying native and invasive fruits consumed or dropped intact by macaques during feeding bouts (n = 114). Macaques fed increasingly on ripe invasive fruits and less on other food items as fruit availability increased, due to preference for invasive fruits and disproportionate availability of invasive vs native fruits. When fruit became scarcer, macaques had larger home ranges, increasingly fed on scarce unripe native and invasive fruits, and expanded their diet by eating orchard crops, indicating use of energy-maximizing strategies. Macaques consumed more native than invasive fruits when unripe and commonly destroyed seeds of native fruits, indicating higher SDE for invasive vs native plants. Higher discard rates of unripe compared to ripe fruits further reinforced these differences in SDE. Our results highlight potential facilitation of plant invasion by an invasive primate, due to foraging strategies shaped by the availability of invasive fruits.

"I Think That's the Most Beneficial Change That WIC Has Made in a Really Long Time": Perceptions and Awareness of an Increase in the WIC Cash Value Benefit.

During the COVID-19 pandemic, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Cash Value Benefit (CVB) for fruits and vegetables increased by roughly USD 25/month/person. We sought to understand WIC participant perceptions of this change and barriers and facilitators to using the CVB. We conducted 10 virtual focus groups (5 rural, 5 urban/suburban) with WIC participants (n = 55) in North Carolina in March 2022. Focus groups were recorded and transcribed. We open-coded the content and used thematic analysis to uncover consistencies within and between sampled groups. Participants expressed favorable perceptions of the CVB increase and stated the pre-pandemic CVB amount was insufficient. Barriers to using the increased CVB were identifying WIC-approved fruits and vegetables in stores and insufficient supply of fruits and vegetables. Barriers were more pronounced in rural groups. Facilitators of CVB use were existing household preferences for fruits and vegetables and the variety of products that can be purchased with CVB relative to other components of the WIC food package. Participants felt the CVB increase allowed their families to eat a wider variety of fruits and vegetables. The CVB increase may improve fruit and vegetable intake, particularly if made permanent, but barriers to CVB and WIC benefit use may limit the potential impact.
