Efficacy and Profitability of Insecticide Treatments for Tomato Spotted Wilt Management on Peanut in South Carolina.

Tomato spotted wilt (TSW) is a common and serious disease of peanut (Arachis hypogaea L.) caused by Tomato spotted wilt virus (TSWV; family Tospoviridae, genus Orthotospovirus). Management frequently uses an integrated approach, with cultivar resistance and application of in-furrow insecticide as two critical components. In-furrow insecticides help suppress thrips, which can injure and stunt young growing plants and transmit TSWV, with postemergent application of acephate capable of providing additional thrips control. To examine effects of systemic insecticides (imidacloprid, imidacloprid plus fluopyram, phorate, and acephate) on TSW management, yield, and economic return across cultivar susceptibilities (susceptible, moderately susceptible, and resistant) in South Carolina, a meta-analysis was used to synthesize results from 32 studies conducted between 2009 and 2018. Although efficacy and magnitude of individual treatments varied with susceptibility, imidacloprid increased, whereas phorate generally decreased TSW incidence relative to nontreated controls. In-furrow treatments followed by acephate further reduced TSW incidence and increased profitability. All examined treatments improved yield compared with untreated peanuts except for susceptible cultivars treated with imidacloprid. Imidacloprid plus fluopyram increased yield more than imidacloprid alone for the susceptible group, although there was little difference between these treatments in association with moderately susceptible cultivars. When comparing individual applications, phorate was overall the most profitable option across susceptibilities, although imidacloprid plus fluopyram exhibited analogous profitability for susceptible cultivars. Results from this study can be used to assist producer selection of management options for TSW in peanut.

The Role of Planting Patterns to Control Thrips from Red Chili Pepper Plants

Chili plants are commodities that are vulnerable to various types of pests, one of the main pests is thrips. This study aims to determine the role of cropping patterns to control thrips from red chili plants, which was carried out in the Maros Regency, South Sulawesi. Planting patterns applied were: 1) chili using plastic mulch without the combination of other plants and the use of pesticides, 2) chili using plastic mulch combined with corn plants, 3) chili without plastic mulch combined with watermelon plants, 4) chili without plastic mulch combined with watermelon and corn plants, 5) chili without plastic mulch combined with corn plants and 6) chili using plastic mulch and pesticides (according to farmers' treatment). The results showed that the highest population of thrips was found in the chili cropping pattern without plastic mulch combined with watermelon and corn plants with as many as 15 T. parvispinus and 32 T. palmi thrips. Meanwhile, the chili planting pattern using plastic mulch without the combination of other plants and with the use of pesticides had the lowest average amount of thrips population weighing at 5.1 T. parvispinus and 9.5 T. palmi. T. parvispinuspopulation was lower at the beginning of the observation (during the vegetative period) and tends to increase during the generative period of chili plants. T. palmi shows the opposite trend, its population tends to be high at the beginning of plant growth (vegetative phase) and decreases its population when the plant enters the generative period. Based on the data and facts found during the study, it is concluded that: 1). The chili cropping pattern without plastic mulch combined with watermelon and corn plants showed the highest average number of thrips population compared to the other cropping patterns. 2). The abundance of populations of the two thrips species showed different fluctuations, where T. parvispinus populations tended to increase in line with plant development and T. palmi decreased according to plant development. 3). In general, the application of intercropping cropping patterns has not yet appeared to play a role in reducing the abundance of thrips population but there is an opportunity to apply cropping patterns as a method to control thrips by selecting plants that are more suitable to be combined with chili plants.

Avaliação de inseticidas para o controle de Thrips tabaci (Lindeman, 1889) (Thysanoptera: Thripidae) em campo, na cultura da cebola

The efficacy of 14 different insecticides was tested for the control of onion thrips Thrips tabaci (Lindeman, 1889) on onion in Itajaí Valley, SC during 2018. The insecticides were sprayed six times at intervals of about seven days, we evaluated the number of nymph of thrips per plant 48 hours after spray, visually rated for thrips damage at 96 DAT and total and commercial onion bulb production. Significant diferences were observed between various insecticides evaluated. The treatments formetanate hydrochloride, spinetoram and abamectin proved the best thrips control, less thrips damage and good total and commercial productivity. The insecticide profenofos + cypermethrin exhibited reduction of thrips nymph and better total and comercial production comparing control however not reduced thrips damages. The insecticides thiacloprid, thiamethoxam + lambda-cyhalotrin, and Imidacloprid reduced the thrips density but had similar results for thrips damages and onion bulb production comparing with control, excepting total productivity for the neonicotinoids thiacloprid and and Imidacloprid.

Relationship between onion thrips (Thrips tabaci) and Stemphylium vesicarium in the development of Stemphylium leaf blight in onion

AbstractStemphylium leaf blight caused by Stemphylium vesicarium and onion thrips (Thrips tabaci) are two common causes of leaf damage in onion production. Onion thrips is known to interact synergistically with pathogens to exacerbate plant disease. However, the potential relationship between onion thrips and Stemphylium leaf blight is unknown. In a series of controlled laboratory and field trials, the relationship between thrips feeding and movement on the development and severity of Stemphylium leaf blight were examined. In laboratory assays, onions (“Avalon” and “Ailsa Craig”) with varying levels of thrips feeding damage were inoculated with S. vesicarium. Pathogen colonisation and leaf dieback were measured after 2 weeks. In pathogen transfer assays, thrips were exposed to S. vesicarium conidia, transferred to onion and leaf disease development was monitored. In field trials, insecticide use was examined as a potential indirect means to reduce Stemphylium leaf blight disease and pathogen colonisation by reducing thrips damage. Results from laboratory trials revealed that a reduction in thrips feeding decreased S. vesicarium colonisation of onion leaves by 2.3–2.9 times, and decreased leaf dieback by 40–50%. Additionally, onion thrips were capable of transferring S. vesicarium conidia to onion plants (albeit at a low frequency of 2–14% of plants inoculated). In field trials, the symptoms and colonisation of Stemphylium leaf blight were reduced by 27 and 17%, respectively with the use of insecticide to control thrips. These results suggest that onion thrips may play a significant role in the development of Stemphylium leaf blight, and thrips control may reduce disease in commercial onion fields.

A survey was conducted in 2016 in the major onion producing areas of the Ethiopian Central Rift Valley. A structured questionnaire was used to assess farmers’ management practices with a focus on the use of insecticides. Plant samples were collected to assess species composition of thrips and their abundance. Results showed that insecticides were the only control methods for onion growers to control thrips infesting onion. The insecticides diazinon, dimethoate, profenofos, lambda-cyhalothrin and spinetoram were commonly used. Level of insecticide use was higher in Meki than Melkassa and Werer. The volume of insecticide for thrips control and thrips population was noted to be on the increase over the years. Frankliniella occidentalis and Thrips tabaci were present in all surveyed areas with T. tabaci accounting for a higher proportion. The relative species composition varied significantly with location. The highest proportion of T. tabaci was recorded at Werer, where insecticide use was relatively minimal. On the other hand, F. occidentalis was highest at Meki where insecticide use was also higher. The study suggests that thrips infesting onion have developed resistance to the commonly used insecticides. Further studies are required to confirm and develop a thrips resistance management program in the area. Key words: Frankliniella occidentalis, Thrips tabaci, onion, species composition.

Efficacy of insecticides for season-long control of thrips (Thysanoptera: Thripidae) in winter strawberries in Florida

Flower thrips (primarily Frankliniella spp.) can be significant strawberry pests, and recently in Florida, Scirtothrips dorsalis Hood has become an established, early-season, foliar pest. Insecticides that were used for flower thrips management are now also used for S. dorsalis, resulting in the need to evaluate newer insecticides in order to diversify rotations and mitigate overuse of insecticides with the same mode-of-action. We evaluated 10 and 12 season-long insecticide programs in field plots in central Florida during the 2016–2017 and 2017–2018 winter strawberry seasons, respectively. We found that most programs reduced thrips populations and strawberry injury due to thrips feeding, while having limited effects on Orius spp., a primary thrips predator. An early season application of chlorantraniliprole + thiamethoxam, commonly used for other strawberry pests, reduced S. dorsalis populations and strawberry injury, although S. dorsalis populations were relatively low in both study years. When repeat applications of the same insecticide were made throughout the growing season, cyantraniliprole was nearly as effective as spinetoram against Frankliniella spp., while tolfenpyrad and sulfoxaflor did not perform as well. Flupyradifurone was as effective as acetamiprid when used as a follow-up application to spinetoram or cyantraniliprole. Programs including or entirely composed of OMRI-listed insecticides for organic production were not as effective as conventional insecticide programs, with only spinosad providing acceptable thrips control. In conclusion, spinetoram, acetamiprid and spinosad were confirmed to be effective against thrips and can be used as the backbone of rotation programs in conventional and organic strawberry production systems. Diamide insecticides were effective when used repeatedly and in rotation, while flupyradifurone and flonicamid may be used when follow-up applications are needed. Continued research is critical for fine-tuning insecticide programs, with a focus on testing against high S. dorsalis populations in early-planted strawberries and on developing effective sampling methods to optimize timing and reduce the number of applications.

Biological Control and IPM in Strawberry Fields—Current Status and Future of IPM in Miyagi Prefecture, Japan

For integrated pest management（IPM）of strawberries in Miyagi Prefecture, Japan, combinations of applications of Phytoseiulus persimilis Athias-Henriot, Neoseiulus californicus（McGregor）, spiracle-blocking insecticides, fumigation using a high concentration of carbon dioxide, and an increase in UV-B radiation using a reflective sheet are currently in use for the control of spider mites. Efforts are underway to improve and expand on these methods. For the control of aphids, application of two natural enemies, Aphidius colemani Viereck and Ephedrus nacheri Quilis, in conjunction with banker plant system is highly effective, and their use is expected to increase over the next few years. For the control of thrips, application of selective pesticide at the initial time of their occurrence after installing red insect-proof nets（mesh size 0.8×0.8 mm）around the opening of the greenhouse is currently used. The possibility of using natural enemies against thrips, such as Haplothrips brevitubus（Karny）, Amblydromalus limonicus（Garman et McGregor）, and Amblyseius cucumeris（Oudemans）, needs further study. For the control of whiteflies, a tape formulation of pyriproxyfen and spiracle-blocking insecticides, as used in the control of spider mites, can maintain populations at a low density. Although there are difficulties in the use of entomopathogenic fungi and indigenous natural enemies due to the cold climate, we need to further examine their efficacity as IPM.

Thrips are dangerous pests of vegetable crops

Goal. To provide information about dangerous pests of vegetable crops — thrips. To describe the morphology and biology of the pest, the methods of spreading and harmfulness, provide information on the necessary phytosanitary measures to restrict its development and reduce the harmfulness, and to justify the need to use alternative biological methods to control the population of thrips in the conditions of the Southern steppe of Ukraine on an example of the most common of them — tobacco thrips (Thrips tabaci Lind.).
 Methods. Informational and analytical. The collection of information was carried out in accessible specialized literature and the Internet.
 Results. The information about sucking pests of vegetable crops - thrips is given. Thrips are known for a long time, they belong to wide polyphages, that is they harm a wide range of cultural and wild plants (from 100 to 400 spesies). On an example of the most common of them — tobacco thrips (Thrips tabaci Lind.) there is given information about the morphology and biology of the pest, the methods of its spreading and harmfulness, as well as the information on the necessary phytosanitary measures for restriction its development and reduction of the harm. This most widespread and dangerous polyphage, due to its close connection with plants, where its entire life cycle develops - from eggs to imago, has inhabited almost all greenhouses. In the natural conditions of the southern region of Ukraine, the tobacco thrips were found on large areas of vegetable crops with the seedling method of their cultivation, mainly cucumbers, tomatoes, onions, cabbage, watermelons, and the like. It harms bulbs in vegetable stores, which leads to a deterioration in the quality of garden plants and gardening material. The reaction of the plant to the damage by the trips is desensitization, which is manifested in growth retardation, distortion and loss of turgor of damaged leaves, which later become yellow and dries. Imago winter, mostly females, in greenhouses - in different slits, and in open ground - in the upper layer of soil at a depth of 7-10 cm, under plant remains or in the rootstock of perennials or weeds. At temperatures below 0 ° С and in the absence of snow cover, insects die. The pest spreads at all stages of development - eggs, larvae, imago - with planting material of vegetable crops (with plants or in soil), transport, containers, workers' tools, their clothes or footwear. This also occurs when collecting, packing and selling contaminated products. This is especially true for cabbage, with which the thrips can get to the greenhouse or indoor plants. In the conditions of the steppe and forest-steppe zones of Ukraine, the tobacco thrips can develop in open soil at temperatures over 10 ° C during the growing season from the second decade of May to the end of September, causing significant damage to vegetable crops. If this is the case, the pest can give 3-4 to 5-6 generations, depending on the weather conditions. In the population control of tobacco thrips, satisfactory results are received by systematic cultivation of plants with the following insecticides: Akketlik, Aktar, Phyitoverm, Karate Zeon, Confidor Maxi (with irrigation water) and others. It is obligatory to change preparations during the growing season. On the onion fields thrips is successfully reduced with insecticide of natural origin Spintor when using periodic spraying of plants. Because thrips are very resistant pests, therefore, in addition to insecticides, the use of predatory mites Amblyseius cucumeris, A. barken, A. derenerans, as well as predators of Orius laevigatus, O. magusaculus can be used to destroy them. Taking into account that nowadays the protection of vegetable crops takes the direction for the use of biological agents against pests - polyphages, special attention should be paid to the use of natural enemies of the tobacco thrips.
 Conclusions. In the natural conditions of the southern region of Ukraine, tobacco thrips were found on large areas of vegetable crops, therefore, there are all reasons for phytosanitary surveys of open-air vegetable crops to detect and eliminate this dangerous pest. Taking into account that nowadays the protection of vegetable crops takes the direction for the use of biological agents against pests - polyphages, special attention should be paid to the use of natural enemies of the tobacco thrips.

Efficacy of binary combinations between methyl salicylate and carvacrol against thrips Anaphothrips obscurus: laboratory and field trials.

Thrips Anaphothrips obscurus are one of the cosmopolitan major pests feeding on cereals and other grasses. In order to develop alternatives of chemical insecticides for thrips control, based on fumigant activity screening and evaluation of 22 essential oil (EO) compounds against the thrips, the binary interactions of methyl salicylate and carvacrol (MS-C) with high fumigant toxicity were studied systematically by bioassay and field trials. The bioassay results showed that six in 22 EO compounds had high fumigant toxicity against both the second-instar nymphs and adults of A. obscurus, including methyl salicylate, carvacrol, thymol, trans-cinnamaldehyde, diallyl trisulfide, and L-perillaldehyde. Furthermore, the combination of methyl salicylate mixed with carvacrol at a volume ratio of 5:5 exhibited the most significant synergism against A. obscurus, with a poison ratio value of 1.32 and a co-toxicity coefficient of 151.15. The optimal formulation of microemulsion (ME) was composed of 5% methyl salicylate, 5% carvacrol, 46% adjuvant and 44% deionized water. The result of dynamic light scattering and stability showed that MS-C 10% ME was a transparent, single-phase and homogeneous liquid system. Field trials indicated that the ME displayed a significant control efficacy of about 89.17% on thrips in peppers, and 82.59% in broad bean on the seventh day post application with a dosage of 600.0 g A.I hm-2 , respectively. The binary combination of MS-C possesses strikingly synergistic action against thrips A. obscurus, and the MS-C 10% ME has the potential to be developed as a botanical pesticide product for thrips control. © 2019 Society of Chemical Industry.

Control of thrips (Enneothrips flavens Moulton.) with synthetic and biological insecticides in different peanut genotypes

In peanut, pests are controlled by application of insecticides throughout the crop cycle, boosting production costs. This study compared the control of thrips (Enneotrhips flavens Moulton) in 10 peanut genotypes by biological and synthetic insecticides in the field in tropical area in Southeastern Brazil (21°13’29.9’’S 48°54’33.0’’W). The experiment was arranged in a randomized block, 10 x 3 factorial design with three replications. The first factor corresponded to 10 peanut genotypes and the second to different insecticides (synthetic, biological and control). The plants were evaluated 36, 44, 51, 59, 65, 72, and 79 days after sowing to determine the number of thrips individuals and the damage on leaflets caused by E. flavens. The plant height (cm), branch length (cm) and pod yield (kg ha-1) were also determined. The data were subjected to analysis of variance and averages compared by Tukey’s test. In prior evaluation carried out before the start of the applications of insecticides (25 DAS), natural infestation of thrips was observed in all genotypes. The genetic variability of lines L. 386 and L. 314 and cultivar IAC 113 was not significant, whereas yield difference was not observed among treatments of insecticides and control, showing tolerance to E. flavens. The synthetic insecticide Engeo PlenoTM showed of 39% higher efficiency (as average) for controlling thrips in peanut. The insecticides Beauveria bassiana (Bals.) (AUIN®) and Metarhizium anisopliae (Metch.) (GR-INN®) have potential to control E. flavens in peanut, but further studies are needed to better define the application date and products doses.

Target-oriented dissemination of the entomopathogenic fungus Fusarium subglutinans 12A by the Western Flower Thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae)

Target-oriented dissemination of entomopathogenic fungi may have benefits for spore dispersal to pest populations. In this laboratory study, target-oriented dissemination of Fusarium subglutinans 12A was investigated using female Frankliniella occidentalis Pergande for the control of thrips. The aim was to determine changes on mortality with infected / un-infected thrips number ranging from one to five or while the moulded cadavers were in the environment and lastly, with spore concentration applied to the food or habitat. Investigations were conducted using Petri dishes and single-cell cage bioassays and spore concentration (1 × 106 spore/ml) of fungus was applied using the dipping method. When the infected thrips were released to uncontaminated individuals mean mortality rate reached 48.2% and an increase in the number of inoculated individuals had no significant effect on mortality rates. On the contrary, an increase in the number of uncontaminated individuals had a significant effect on mortality rates, in which four uncontaminated thrips were released with infected thrips and the mortality rate reached 60.4%. Results revealed that the presence of 1 × 106 spore/ml of fungus in the habitat raised the mortality rate to 90.9 ± 2.4% on the 7th day. In the experiment where cadavers were present in the environment, the mortality rate reached 45.7 ± 3.7% on the 8th day. Overall, the results suggest that F. subglutinans 12A can be effectively disseminated to uninfected individuals by releasing conspecifics of F. occidentalis inoculated with 1 × 106 spore/ml and the most effective factor was found habitat applications to the determining dissemination of fungus.

<p class="Body">Life tables and feeding habits of Proprioseiopsis lenis (Acari: Phytoseiidae) and implications for its biological control potential in Southeast Asia

Development, survival and reproduction of Proprioseiopsis lenis (Corpuz and Rimando) (Acari: Phytoseiidae), a predatory mite distributed in parts of Southeast Asia, were assessed on different foods. These included four pollens (Typha latifolia, Luffa aegyptiaca, Zea mays, Ricinus communis), the natural prey Tetranychus urticae (mixed stages) and Frankliniella occidentalis (first-second instars), and the storage mite Carpoglyphus lactis (mixed stages) as a factitious prey. The total immature developmental time of females fed at 27 °C on T. latifolia pollen (4.1 days) or C. lactis (4.0 days) was significantly shorter than that of those offered Z. mays pollen (5.3 days), R. communis pollen (6.7 days) or T. urticae (4.3 days). Nearly 60% of the predators fed on R. communis pollen died in the immature stages and adult females failed to produce eggs. The daily oviposition rate of P. lenis reared on C. lactis (2.9 eggs/female/day), T. latifolia pollen (2.7 eggs/female/day) and F. occidentalis (2.6 eggs/female/day) was significantly higher than that of females maintained on the other diets. Total fecundity of females offered C. lactis (37.3 eggs/female) was highest, followed by F. occidentalis (26.5 eggs/female), T. urticae, L. aegyptiaca pollen, and T. latifolia pollen and was lowest on Z. mays pollen (7.4 eggs/female). The intrinsic rates of increase (rm) were highest on C. lactis (0.293), T. latifolia pollen (0.285) and T. urticae (0.283), followed by F. occidentalis (0.260) and L. aegyptiaca pollen (0.233) and were lowest on Z. mays pollen (0.115). Our findings suggest that P. lenis may have potential as a natural enemy to be used in augmentative biological control of spider mites and thrips in Southeast Asian greenhouse or field crops. The predator can be reared on the storage mite C. lactis and can also survive on several pollens in case prey is scarce or absent in the crop.

Survey of flowering plants in Hawaii as potential banker plants of anthocorid predators for thrips control

Abstract Flowering plants in gardens and along roadsides on the Big Island of Hawaii were sampled for thrips and anthocorid predators of thrips. A total of 171 plant samples, comprising 859 plant sample units (e.g. flowers or flower clusters) were collected from 56 species of plants in 25 families. Adult thrips were found on 43 plant species, and 32 of these also had larval thrips of the same species, indicating the plant species was a breeding host for thrips. Five different species of anthocorids – Orius persequens, Orius tristicolor, Paratriphleps laeviusculus, Montandoniola confusa, and Blaptostethus pallescens – were collected on 22 different plant species in 10 plant families. The plants with the highest numbers of anthocorid adults and nymphs present were Macaranga tanarius (Blush Macaraga), Verbesina encelioides (Golden Crownbeard), Tithonia diversifolia (Tree Marigold), Acalypha hispida (Chenille bush), and Coreopsis lanceolata (Lance-leaf Coreopsis). Macaranga tanarius was found to be the best host plant for anthocorids, with an average of 25.5 adult and 21.1 larval anthocorids per plant sample. Orius persequens was the most abundant anthocorid on M. tanarius with average adult and larval densities of 24.1 and 17.3 per plant sample, respectively. None of the insects found in association with M. tanarius are known pests. Macaranga tanarius has great potential as a banker plant to help suppress thrips populations in greenhouse crops with anthocorid predators.

Pollen Provisioning Enhances the Performance of Amblydromalus limonicus on an Unsuitable Prey

Amblydromalus limonicus is a polyphagous phytoseiid predator used for the biological control of thrips and whiteflies in greenhouse crops. Besides various prey species, A. limonicus can also feed on pollen of different plants. Cattail pollen has been previously shown to be suitable for the development and reproduction of A. limonicus. Hence, it could sustain its populations in periods of prey scarcity. In the present study, we hypothesized that pollen provisioning may benefit A. limonicus in mixed diets with prey of low quality, such as spider mites and thus, positively impact ecosystem services provided by this predator. For this, the performance and predation efficiency of A. limonicus against spider mites was assessed in the presence or absence of pollen. Our results show that pollen significantly shortens the developmental time and increases the survival and oviposition of the predator when mixed with spider mites, although it negatively affects its predation rate. Nevertheless, pollen enhances the maintenance of juvenile predators on the leaf by substantially decreasing their dispersal rate in the mixed diet with spider mites. In addition, the intrinsic rate of population increase (rm) of A. limonicus feeding with spider mites increased with the addition of pollen suggesting an increase in its population. Cattail pollen as supplementary food may thus expand the prey species range that A. limonicus could exploit. It can also enhance ecosystem services provided against other pests (thrips and whiteflies) by positively affecting the increase of A. limonicus population.

Analysis of seasonal and annual field-evolved insecticide resistance in populations of Thrips hawaiiensis in banana orchards

Every season over the past decade, efficacious thrips insecticides have been commonly applied for control of Thrips hawaiiensis on banana crops in China. For effective thrips control, some insecticides have been used extensively against the thrips in numerous banana plantations. This study aims to examine the current resistance status and the dynamics regarding the changing frequencies of resistance in the field T. hawaiiensis populations. A total of 13 field samples from banana orchards (Chengmai, Lingao, Dongfang and Ledong located in Hainan Province, China) were collected monthly in 2014 to 2017, and selected individuals were used in bioassays assessing insecticide resistance and metabolic enzyme activity compared to a laboratory-susceptible strain. In 2014, the initial resistance survey found that all sampled populations were susceptible to spirotetramat and cyantraniliprole, while Lingao and Chengmai population showed a moderate resistance to imidacloprid, acetamiprid, abamectin and spinetoram. Further, seasonal and annual analysis of resistance dynamics with imidacloprid, abamectin and spinetoram demonstrated that resistance in field populations of T. hawaiiensis developed quickly within a season (from April to August 2016), but resistance was unstable over subsequent seasons (April 2015, 2016 and 2017). Moreover, synergism experiments using enzyme inhibitors together with metabolic enzyme assays revealed that field-evolved insecticide resistance in T. hawaiiensis was closely associated with the elevated metabolic enzymes. The observed resistance increase within a season was attributed mainly to the intense use of these insecticides and short generation time of thrips. These findings suggest that a rotation system using efficacious thrips insecticides should be implemented for sustainable thrips control to reduce the potential of resistance development.
