“…Menochilus sexmaculatus was most commonly found as a predator of S. frugiperda in this study because this beetle has a wide range of prey [17]. Apart from aphids, M. sexmaculatus is also known to prey on the whitefly Bemisia tabaci Setiawati, et al [24] and Diaphorina citri [25]. Among the prey that has been mentioned, M. sexmaculatus has a preference for Aphis gossypii.…”

This research was conducted to identify and found the abundance of predatory insect species of S. frugiperda in Sleman and Gunungkidul Regencies, Yogyakarta Province, Indonesia. This research was conducted in June 2021 - March 2022 on corn plantations in Sleman and Gunungkidul Regencies. Determination of the sampling location was determined by stratified random sampling. Corn land used in sampling was determined by purposive. Insect predator caught by using sweeping net and hand picking. The results showed that there are 3 orders, 8 families, and 16 species of insect predators. 3 orders of the insect predators that found in the Sleman and Gunungkidul Regencies were Coleoptera, Hymenoptera, and Hemiptera. Insect predator families that found in Sleman dan Guungkidul Regencies were Coccinellidae, Carabidae, Staphylinidae, Formicidae, Vespidae, Pentatomidae and Reduviidae. Insect predators species that was most commonly found was Menochilus sexmaculatus with 467 individuals and the least was Sycanus sp. with 1 individual. The conclusion of this study is that there were 16 species of predators from S. frugiperda in Sleman and Gunungkidul Regencies. Practical implications of this research were the insect predators that found in Sleman and Gunungkidul Regencies can be used to maintain the population of Spodoptera frugiperda in two regencies.

“…Rodrı ´guez-Lo ´pez et al [70] observed that the primary and secondary spread of TYLCV by viruliferous whiteflies in greenhouse studies to their acylsugar-accumulating tomato line decreased and was dependent on the time of year and concluded that acylsugarmediated resistance in the lines tested was optimal in warm and dry growing regions and not likely to provide adequate virus protection for younger plant stages. Setiawati et al [79] evaluated several tomato varieties in a field trial and observed variation in whitefly abundance that was correlated with trichome abundance, but they did not evaluate the amount of acylsugars accumulated or acylsugar chemistry. Marchant et al [72] evaluated some of the same lines used in our study using lab assays, finding negative impacts of in planta produced acylsugars on whiteflies and a negative correlation between acylsugars and whitefly acquisition as well as…”

The objectives of this study were to ascertain the impact of endogenous production of trichome-exuded acylsugars on insects and insect transmitted virus by evaluating tomato lines and their hybrids bred for acylsugar production under field settings on whiteflies and the whitefly-transmitted tomato yellow leaf curl virus. Specifically, we utilized a diverse array of tomato lines and hybrids bred for changes in acylsugar amount or type, grown in three field trials under natural whitefly and virus pressure, to investigate whether the amount of accumulated acylsugars and or the chemical profile of the acylsugars were associated with greater resistance to whiteflies and reduced incidence of tomato yellow leaf curl virus. There was considerable variation in the abundance of whitefly eggs and nymphs and incidence of tomato yellow leaf curl virus across experiments and between entries. Increasing amount of acylsugars accumulated by the tomato entries was associated with a reduction in the abundance of whitefly eggs and nymphs and a reduction in the incidence of tomato yellow leaf curl virus. Additionally, we identified lines with changes in several acylsugar fatty acids that were associated with decreased abundance of whitefly eggs and nymphs and reduced incidence of tomato yellow leaf curl virus. These results inform the utility of acylsugars as a host plant defense system for improving resistance to whiteflies and their transmitted viruses, with potential for reducing insecticides as a control method for whiteflies and provide breeding targets for optimization of existing acylsugar tomato lines to create lines with the most efficacious amount and chemistry of acylsugars.

White flies Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) is a damaging sap-sucking insect pest of ornamental and vegetable crops. It causes yield reduction and crop damage by feeding on both immature and mature plants as well as spreading viral infections. Due to their widespread use throughout the world, synthetic chemical pesticides have a negative influence on human health, the environment, crop yield, and pollinator health. A few species have also evolved resistance to these pesticides. Sustainable and environmentally responsible management techniques are becoming more and more necessary to control whitefly populations as ecological concerns rise. The purpose of this review is to provide an overview and assessment of the effectiveness of various ecological management techniques used in vegetable crops to manage whiteflies. The review includes cultural, physical, and biological techniques as well as preventive and therapeutic treatments. Through altering their life cycle and habitat, cultural methods like crop rotation, intercropping, and trap cropping have showed promise in lowering whitefly populations. Physical controls like reflecting mulch, insect-proof screens, and sticky traps have proven successful in catching adult whiteflies and limiting their population. The employment of natural enemies like parasitoids, predators, and entomopathogenic fungi in biological control strategies has shown to be highly effective in reducing whitefly populations. These techniques reduce detrimental effects on the environment and human health in addition to providing long-term and sustainable management. These methods support environmentally sound and economically successful sustainable agriculture systems by fostering biodiversity, protecting natural enemies, and lowering the use of synthetic pesticides.
