Influence of Inert Minerals and Botanicals on Adult Emergence of Pulse Beetle, Callosobruchus maculatus (Fabricius), in Stored Blackgram

Background: Pulses hold significant global importance as a food source, with the pulse beetle, Callosobruchus maculatus, being a major pest affecting them. As consumer preferences shift towards insecticide residue-free food, pest management strategies are adapting. Inert minerals and botanicals offer a promising solution to address concerns about insecticide safety, resistance development, and regulatory standards. Hence, this study seeks to assess how these substances impact the emergence of C. maculatus adults. Methods: One kilogram of blackgram was taken in three replications and treated with inert minerals and botanicals. In each container, ten pairs of newly emerged adult beetles were introduced. A subsample of 50 g was taken in small plastic jars to record, the day when the first adult beetle emerged, the daily count of adult beetles, and the overall count of emerged adult beetles. Result: The research showed no significant difference between treatments and untreated control w.r.t day of first adult emergence of C. maculatus. The percentage of adult emergence of C. maculatus in blackgram seeds treated with diatomaceous earth was 21.06% which was significantly the lowest value when compared to untreated control (86.03%). The total count of emerged adult beetles from the main sample was less in diatomaceous earth (135.33 adults) against untreated control (751.67 adults). Among all the treatments tested, diatomaceous earth performed better in controlling the adult emergence of C. maculatus.

The Status of Beekeeping in Simada District, Amhara, Ethiopia, with Its Challenges and Opportunities

The study was designed to assess the existing beekeeping practices, constraints, and potential of honeybee production in Simada district. The study was carried out in four proportionally selected kebeles of highland, midland, and lowland agro-ecology. Accordingly, a total sample size of 146 beekeepers, depending on their potential, was interviewed using a structured and semi-structured questionnaire. A semi-structured questionnaire, field observation, and focal group discussion were employed to collect primary data. Descriptive statistics such as mean, frequency, and standard deviation were used to analyze the data. The majority of beekeepers in the district are mail-headed, and the majority can read and write. Beekeepers practiced three hive types but mostly used traditional hives. The majority of honeybee colonies are found in midland agro-ecology, but they are not significantly different (P<0.05). About 57.5% of beekeepers obtain their colony through buying, and their colony increases through reproductive swarming. Beekeepers construct both traditional and top-bar hives from the surrounding available material. Frame hives were obtained from GOs on a credit basis. Beekeepers indicated that the majority of honey was harvested in October and November. The second minor harvesting period was from May to June, which depends on the nature of the yearly rainfall conditions. As the respondent's described, they stored honey below one year in a plastic jar, clay jar, and plastic sack when plenty of products were obtained and for medicinal value, unless they used honey during harvesting as a source of income. Predators and pests are major constraints on honey bee production, followed by pesticides and herbicides in the study area. Other identified beekeeping constraints were shown in relative order of importance: drought, death of colony, lack of water, migration, and disease are some of the problems that hinder productivity. Honeybees required feed supplementation during the dry season; about 28% of beekeepers fed their colonies with higher supplements made from February to April. The commonly used supplements were peas and bean flour (Shiro), barley flour (Besso), sugar, honey, and others, including Niger.

Combining Urea with Chemical and Biological Amendments Differentially Influences Nitrogen Dynamics in Soil and Wheat Growth.

Nitrogen (N) losses from fertilized fields pose a major concern in modern agriculture due to environmental implications. Urease inhibitors, such as N-(n-butyl) thiophosphoric triamide (NBPT), nitrification inhibitors (NI), like dicyandiamide (DCD), and sulfur-oxidizing bacteria (SOB) could have potential in reducing N losses. For evaluating their effectiveness, investigations were undertaken through incubation and greenhouse experiments by mixing a urea fertilizer with sole NBPT, DCD, and SOB, as well as combined, on ammonia volatilization losses from silt loam soil. An incubation experiment was conducted in 1 L airtight plastic jars with adequate aeration and constant temperature at 25 °C for 10 days. Three replications of each treatment were conducted using a completely randomized designed. The ammonia emission rate gradually increased until the highest (17.21 mg NH3 m-2 h-1) value on the third day with sole urea and some other treatments except NBPT alone, which prolonged the hydrolysis peak until the fifth day with the lowest ammonia emission rate (12.1 mg NH3 m-2 h-1). Although the DCD and SOB treatments reduced ammonia emission, their difference with urea was nonsignificant. Additionally, mixing NBPT with urea exhibited the highest population of nitrifying bacteria in soil, indicating its potential role in promoting the nitrification process. In a greenhouse experiment, 10 treatments, i.e., T1 = control, T2 = N120 (urea fertilizer equivalent to 120 kg N ha-1), T3 = N90 (90 kg N ha-1), T4 = N90 + NBPT, T5 = N90 + DCD, T6 = N90 + SOB, T7 = N90 + NBPT + DCD, T8 = N90 + NBPT + SOB, T9 = N90 + DCD + SOB, and T10 = N90 + NBPT + DCD + SOB, were applied to investigate the wheat yield and N uptake efficiency. The highest N recovery efficiency (31.51%) was recorded in T5 where DCD was combined with urea at 90 kg ha-1.

Effect of Seed Storage Duration and Methods on Growth and Yield of Basil Variety

The experiment was conducted at Wondogenet Agricultural Research Center to determine the effect of seed storage period and methods on the growth and yield of basil. Basil seeds stored in three storage methods (Plastic jar, Polypropylene, and Cotton bags) for six storage periods (initial period, one, three, six, nine, and twelve months) were used to evaluate the impact of the treatments on the yield and performance in the field. The field experiment was arranged by using RCBD design with three replications. The data were taken at the 90% physiological maturity stage. The results showed a significant difference between the treatments. The results indicated that the interaction effects of basil seed storage time and methods had a significant (P<0.05) effect on Primary Branch Number, Plant Height, Umbrella length, Dry, and Fresh biomass. The umbrella number of the storage methods had an accelerating trend with raising storage duration to 3 months storage, after that it shows a declining trend with raising storage time. The two storage methods plastic jar and bag maintained the seed in good condition for 3 months further, storage of the seed leads to the shortest plant and umbrella length. The highest dry biomass was recorded at 3 months stored seed in a plastic bag which was not significantly different from 3 months stored seed in a plastic jar. Basil dry biomass for the jar stored seed ranged from 0.85 to 3.33, 0.91 to 3.42 ton/ha for plastic bag whereas for the cotton bag, it ranged from 0.6 to 2.26 ton/ha. In general, seeds stored for three months had shown better growth and yield.

The experiment was conducted at the Seed Research and Technology Centre, PJTSAU, Rajendranagar, Hyderabad, to investigate the impact of Sitophilus oryzae on the seed quality parameters of maize. Samples weighing 500g of maize variety DHM-117 were placed in plastic jars in three replications S. oryzae adults of 0, 5, 10, 15, and 20 pairs were separately released into each replicate of the maize seeds then these jars were placed in an incubator set at 25°C and 75% humidity. These jars were covered with lids equipped with aeration facilities. The adult emergence, germination percentage and moisture content were evaluated every two months six months. An inverse correlation was observed between adult emergence with germination percentage and seedling vigour index while, adult emergence showed a positive correlation with moisture content.

Heterorhabditis indica (Nematoda: Rhabditida) a possible new biological control agent against the vector of Chagas disease

Chagas disease is a zoonosis caused by the protozoan Trypanosoma cruzi and transmitted through the feces of triatomines, mainly in Latin America. Since the 1950s, chemical insecticides have been the primary method for controlling these triatomines, yet resistance has emerged, prompting the exploration of alternative approaches. The objective of this research was to test the capacity of the entomopathogenic nematodes Heterorhabditis indica and its symbiotic bacteria Photorhabdus luminescens, to produce mortality of Triatoma dimidiata a key vector of T. cruzi in Mexico under laboratory conditions. Two bioassays were conducted. In the first bioassay, the experimental unit was a 250 ml plastic jar with 100 g of sterile soil and three adult T. dimidiata. Three nematode quantities were tested: 2250, 4500, and 9000 nematodes per 100 g of sterile soil (n/100 g) per jar, with 3 replicates for each concentration and 1 control per concentration (1 jar with 100 g of sterile soil and 3 T. dimidiata without nematodes). The experimental unit of the second bioassay was a 500 ml plastic jar with 100 g of sterile soil and 4 adult T. dimidiata. This bioassay included 5, 50, 500, and 5000 n/100 g of sterile soil per jar, with 3 replicates of each quantity and 1 control per quantity. Data were analyzed using Kaplan-Meyer survival analysis. Electron microscopy was used to assess the presence of nematodes and tissue damage in T. dimidiata. The results of the first bioassay demonstrated that the nematode induced an accumulated average mortality ranging from 55.5 % (2250 n/100 g) to 100 % (4500 and 9000 n/100 g) within 144 h. In the second bioassay, the 5000 n/100 g concentration yielded 87.5 % mortality at 86 h, but a concentration as small as 500 n/100 g caused 75 % mortality from 84 h onwards. Survival analysis indicated higher T. dimidiata mortality with increased nematode quantities, with significant differences between the 4500, 5000, and 9000 n/100 g and controls. Electron microscopy revealed the presence of nematodes and its presumably symbiotic bacteria in the digestive system of T. dimidiata. Based on these analyses, we assert that the H. indica and P. luminescens complex causes mortality in adult T. dimidiata under laboratory conditions.

Responses of nematodes to oil contamination in a mangrove sediment: A microcosm study

The effects of oil pollution on nematode assemblages were investigated in a mangrove sediment. Microcosms comprised 350 mL plastic jars filled with 250 g sediment. In the oiled treatments (O), 15 mL oil were added to the soil. In the oil and fertiliser treatments (O + F), oil and fertiliser (N: P: K: 3: 2: 5) were added to the soil. After four weeks, nematodes were extracted and identified. The number of nematode taxa was highest in the C (61), intermediate in the O + F (59) and significantly lower in the O (25) treatment. Taxa present in the C but absent in the O treatment were oil-intolerant. Taxa present in the O treatments were oil-tolerant. Five taxa survived oiling probably due to fertiliser amendment. Oiling eliminated oil-intolerant taxa and favoured those that were resistant. In the O+ F treatment, the number and species of nematodes increased significantly.

Effectiveness of B14A probiotic candidates as enhancers on the physical characteristics and organoleptic properties of bekamal

Bekamal is a fermented meat typical of Banyuwangi Regency which is produced traditionally with the addition of sugar and salt as a preservative and flavor enhancer. The weakness of commercial bekamal takes a long time because the meat must be fermented for 3 to 6 months to get some unique taste, which has a juiciness, slightly sour and salty that consumers like. The B14A probiotic candidate is added to the bekamal ingredients to help speed up the fermentation process with similar characteristics to commercial bekamal. Bekamal with B14A isolate is begun by regenerating the isolate to become a starter culture. The 10% starter culture is inoculated into the pieces of meat and added by 7.5% palm sugar and 7% salt then fermented in some plastic jars with three variables of fermentation time, there are 7, 14, and 21 days. Bekamal in each fermentation time treatment was tested on physical characteristics that consist of yield, cooking loss, water holding capacity (WHC), and organoleptic properties like taste, color, aroma, and texture. The results showed that the B14A probiotic candidate can speed up the fermentation in less than 1 month (21 days) with physical characteristics and organoleptic properties as well as commercial bekamal.

Physicochemical Quality of Total Mixed Ration Silages Based on Cynodon dactylon and Gliricidia sepium

A mixture of legumes with grasses has been shown to improve silage's physical and nutritional qualities. This study assessed the chemical composition and physical characteristics of Cynodon dactylon (CD) when mixed with different proportions of Gliricidia sepium (GS). Chopped and wilted leaves of CD and GS were mixed in the following combinations: P1: 0% GS + 78% CD; P2: 28% GS + 50% CD; P3: 39% GS + 39% CD; P4: 50% GS + 28% CD; P5: 78% GS + 0% CD. Each combination is enriched with 10% rice bran (RB), 10% Corn Feed (CF) and 2% molasses. A 750 g of the fresh materials were compressed into plastic jar silos and kept for 21 days. The physical characteristics and the loss of chemical composition of silage were analyzed descriptively. pH value and the chemical composition data were subjected to analysis of variance (ANOVA) in a randomized complete design with five replications. Considering all physical and chemical characteristics, GS and CD can be combined as silage material. However, the study recommends including 28-39% GS (P2 and P3) as the most suitable in response to pH value, color, aroma, texture, and presence of fungus.

Effect of 17α-methyl testosterone on sex reversal and growth performance of Nile tilapia,Oreochromis niloticus

The present study aimed at developing all-male Nile tilapia using17α-methyl testosterone(17α-MT) along with its growth and feed utilization performances. Three days old Niletilapia fry were stocked in plastic jars with 5 L capacity installed in four fiber glass tanks. The fry were fed with 0, 30, 60, and 100 mg MT/kg diets for 30 days. Later, the fry were shifted to hapas installed in a pond and then, reared for four months separately. The fish were fed with the control diet. The results showed that the highest male population(93.6%) was observed in the fish treated with a 60 mg MT/kg diet, while the lowest(82.6%) was observed in the fish treated with a 30 mg MT/kg diet. The results also showed that the fish fed with a 60 mg MT/kg diet had significantly higher mean body weight (24.1±1.40 g), specific growth rate (2.5±0.10%), feed conversion ratio (1.3±0.10), and protein efficiency ratio (0.63±0.11) than the untreated fish treated (control) group. In conclusion, a 60 mg MT/kg diet can be considered as an optimal and economically viable dose for Nile tilapia sex reversal along with its optimum growth and feed utilization performances.

Effects of rosehip sauce on chemical, oxidative and sensorial quality of marinated anchovy (Engraulis Encrasicolus Linnaeus, 1758)

Marinated anchovies are of economic importance in Turkey. However, natural antioxidants affecting quality of marinated anchovies are rarely addressed. The purpose of this study is to compare olive oil and rosehip sauce as fillers in anchovy marinades. The study investigated the effects of rosehip sauce on the quality of marinated anchovies stored at 4°C. Anchovy were marinated with 4% acetic acid and 12% NaCl, put into plastic jars, filled with either olive oil or rosehip sauce and stored at 4°C. Changes in sensory attributes were determined during the process, and the following chemical parameters were monitored: total phenolic content (mg/100 g GAE), total volatile basic nitrogen (mg/100 g), pH, peroxide value (meq/kg) and thiobarbituric acid (mg MDA/kg). Values of total volatile basic nitrogen (TVB-N), peroxide value (PV) and thiobarbituric acid (TBA) increased during the storage. Higher values of TVB-N, TBA and PV were found in samples with olive oil than those with rosehip sauce. Samples with rosehip sauce demonstrated better oxidative stability. Rosehip sauce samples had higher appearance, odor, color and texture scores than olive oil samples.

Effect of storage age and containers on the physicochemical degradation of guggul oleo-resin

Guggul is a gum oleo-resin, tapped from a data deficient plant- Commiphora wightii (Arnott.) Bhandari in India. It is extensively used in ayurvedic drugs and formulations since ages. Natural plant-based products; especially aromatic ones like guggul gum oleo-resin deteriorates, qualitatively during its storage and transits before reaching the industry for its value addition. This economical and ecological loss can be avoided if it is stored in proper containers. Physico-chemical degradation of guggul samples stored were analysed by scanned electron microscopy, fourier transformed infra red, thermogravimatric, Powdered X-ray diffraction and elemental analysis for carbon, hydrogen, nitrogen and sulphur. Physico-chemical degradation of guggul oleo-resin occurs with the age of storage and the type of storage containers used. Among the four storage containers (earthen pot, plastic jar, polythene bag, jute bag) evaluated, earthen pot was found to be the best in checking the qualitative loss of guggul even upto 24 months. The qualitative information generated in the study on guggul storage may be useful to the drug industry and guggul traders. It may encourage them practice storing guggul in earthen pots against current practice of using jute bags and polythene bags, to store it.

Effect of Pyriproxyfen, a Malaria Vector Larvicide, on the Growth and Mortality of Vannamei Shrimp

Anopheles mosquito shared a breeding site with the vannamei shrimp (Litopenaeus vannamei). Anopheles mosquito larvae commonly live in both stagnant fresh and brackish water. The potential breeding habitat of Anopheles mosquito larvae may be rice fields, pools or ponds, swamps, ditches, and slow-current streams. One of the effective strategies to control malaria is to apply chemical insecticides. Pyriproxifen is a larvicide that contains juvenile hormone-like compounds. Juvenile hormone-like compounds can affect mosquito morphogenesis, characterized by the failure of the larvae to develop into pupae. With a completely randomized design, the shrimp fry was divided into 4 groups, 6 repetitions, 20 individuals each. Shrimp fry in each experimental unit was placed and maintained in plastic jars containing 2.5 L of brackish water. The results showed that the insect growth regulator (IGR) with the active ingredient pyriproxyfen at various concentrations had no significant effect on the growth, mortality, and survival of vannamei shrimp fry. It can be concluded therefore that pyriproxifen larvicide was safe to be used for controlling malaria mosquito vectors in hatcheries and breeding ponds of vannamei shrimp.

Toward a Diverse Next-Generation Energy Workforce: Teaching Artificial Photosynthesis and Electrochemistry in Elementary Schools through Active Learning

Artificial photosynthesis is a promising approach to generate commodity chemicals using abundant chemical feedstocks and renewable energy sources. Despite its importance, affordable and effective hands-on classroom activities that demonstrate artificial photosynthesis and teach key concepts, especially for primary school students, are lacking. Educating young students on this topic is a critical step in the development of the next-generation energy workforce, especially one that is diverse in race and gender. We hypothesize that an effective approach to educate a broad range of young students on the topic of artificial photosynthesis is through the use of an active learning-based lesson plan that employs cheap and accessible materials. This hypothesis is confirmed by evaluating the understanding of fifth grade students with a survey before and after a lesson plan on artificial photosynthesis that uses active-learning techniques and uses safe and highly accessible materials (baking soda, tap water, plastic jars, Ni coil, alligator clips, and a solar cell) to perform solar-powered water splitting. The lesson plan and survey questions are designed to align with the educational outcomes for fifth grade classrooms in California and to address four general learning objectives: (1) Motivations of Artificial Photosynthesis, (2) Applications of Artificial Photosynthesis, (3) Inputs and Outputs of Artificial Photosynthesis, and (4) Engineering Design for Artificial Photosynthesis. The survey data demonstrate a statistically significant improvement in overall student understanding from the lesson plan. Importantly, the data show that the lesson plan presented here is effective at narrowing the performance gap between minority students and overly represented groups.

Pengaruh suhu dan tempat penyimpanan terhadap kadar air dan mutu organoleptik biskuit subtitusi tepung belut (Monopterus albus zuieuw)

Biscuits with eel flour substitution contained high energy and protein. Food spoilage during storage is caused by water absorption from food storage. This study examines the effect of storage on the water content of biscuits and organoleptic quality. This research was a quasi-experiment conducted by laboratory analysis of the moisture content of biscuits with the addition of eel flour (Monoptherus albus zuieuw). The experiment was conducted at Jayapura Health Polytechnic Laboratory, consisting of 3 formulas (10, 20 and 30 grams) of eel flour substitution. They were packaged using PP plastic and glass jars. The observations were conducted for seven days at temperatures of -18°C and 45°C. Organoleptic test using 17 somewhat trained panellists. Analysis using Independent T-Test. The results showed that biscuits stored at -18°C experienced an increase in water content on the seventh day. Biscuits stored in plastic packaging have a higher water content than glass jars. There was no significant difference in the water content of biscuits stored in jars and plastics (p=0,631). Organoleptic analysis showed that on the sixth day, there was a change in the preference for taste and texture stored in plastic at temperatures of 45°C. In conclusion, there was no significant difference in the moisture content of the biscuits stored in glass or plastic jars. However, there was a decrease in preference on the sixth day of plastic packaging.

Effects of Xylanase and Bacterial Inoculants on In Vitro Rumen Fermentation Pattern of Seasonal Pasture Hay and Green Maize Based Silage

The present study was conducted to evaluate the effects of xylanase and bacterial inoculants on in vitro rumen fermentation pattern of seasonal pasture hay and green maize based silage. Different silages were prepared by using green maize fodder and seasonal pasture hay in the proportion of 10:0 & 7:3 ratio in plastic jars of 3 kg capacity by adding common salt @ 0.5%, urea @ 1% and molasses @ 1.5% in each silage with seven different treatments, viz., Control (only green maize), PH (green maize and seasonal pasture hay in 7:3 ratio), X (PH added with xylanase), LP (PH added with L. plantarum), LF (PH added with L. fermentum), LPLF (PH added with both bacterial inoculants) and XLPLF (PH added with xylanase and both bacterial inoculants). Xylanase, L. plantarum and L. fermentum were used @ 1500 IU/g, 1 x 106 cfu/g and 2 x 106 cfu/g, respectively. All silages were used for in vitro study after 45 days of ensiling. None of the additives affected rumen pH. IVDMD (in vitro dry matter degradability ) was found significantly (p<0.05) higher in X, XLPLF and LPLF silages. All additives significantly (p<0.01) increased IVOMD (in vitro organic matter degradability) except LF silage as compared to PH silage. Values for total gas production and TVFA (Total volatile fatty acids) production were significantly (p<0.001) increased during in vitro rumen fermentation and that of PF (partitioning factor) were significantly (p<0.001) decreased in all additives inoculated silages as compared to PH silage. Content of NH3-N (Ammonia nitrogen) was significantly (p<0.001) higher in LP silage and that of total N was significantly (p<0.001) higher in X, LP, XLPLF silages as compared to PH silage during in vitro study. It could be concluded that xylanase and lactic acid bacterial (LAB) inoculants improved rumen fermentation quality of silage. Among all additives, xylanase is the best silage additive to improve in vitro rumen fermentation pattern.
