Summary: This study investigated the functions of the CSP2 gene in the whitefly Bemisia tabaci, revealing its binding affinity to various plant volatiles and identifying key amino acid residue Y11 essential for binding to DMNT. Furthermore, CSP2 showed high sequence similarity with CSPs of other insect family members, highlighting its potential role in mediating responses to plant volatiles and implications for pest management strategies.

Summary: The whitefly is a destructive insect pest that causes significant crop damage through direct feeding and transmission of diseases. Traditional synthetic pesticides have adverse effects, making it necessary to explore suitable and safe strategies for whitefly management. However, research on whitefly-resistant transgenic plants is limited.

Summary: This study identified a highly resistant Bemisia tabaci population to dinotefuran, a new neonicotinoid insecticide. The resistance was found to be polygenic and incompletely recessive. The study revealed the involvement of P450 enzymes, particularly the CYP6DW5 gene, in the resistance mechanism. This information is important for resistance management in B. tabaci.

Summary: The study evaluated the effects of foliar spraying with systemic insecticides on the probing behavior of non-viruliferous and ToCV-viruliferous B. tabaci and ToCV transmission in potato plants. Results showed that the transmission of ToCV was reduced mainly in plants treated with flupyradifurone and acetamiprid.

Summary: This study found that previous infestation by MEAM1 and MED whiteflies induced defense responses in cabbage plants, which had different effects on the host preference and performance of later-arriving con- and heterospecific whiteflies. Phenolic compounds may be the key factors influencing host choice by MEAM1 and MED whiteflies on cabbage plants.

Summary: Flavonoids in plants have been shown to have pleiotropic effects in defense against abiotic and biotic stresses. This study investigated whether seed priming with rutin, a type of flavonoid, can enhance tomato resistance against the whitefly. The results showed that rutin seed treatment reduced the developmental rate and feeding efficiency of the whitefly, and was associated with increased flavonoid accumulation and expression of defense genes. These findings suggest that seed treatment with rutin can prime tomato resistance against the whitefly without affecting shoot growth.

Summary: RNA interference (RNAi) is a powerful biotechnology that can be used for studying gene functions and pest control. This study identifies a taste receptor gene in the whitefly Bemisia tabaci and demonstrates that silencing this gene through RNAi inhibits the whitefly's sensitivity to sucrose.

Summary: Heavy metal contamination, especially cadmium, poses serious threats to the ecosystem and human health in China. This study investigated the effects of cadmium stress on the bacterial and fungal communities in whiteflies, revealing changes in community composition and diversity. The findings suggest that the whitefly microbiota may contribute to their adaptation and resistance to cadmium and could potentially be utilized for cadmium remediation.

Summary: This study investigated the spatiotemporal distribution of the invasive brown marmorated stink bug in orchard systems, revealing that both adults and nymphs primarily aggregate in peach and adjacent woodlands, reaching peak levels in July and August. The study also found that noncrop host plants play an important role in maintaining the population of this pest.

Summary: Urbanization has clear impacts on the fitness of house wren nestlings, with urban broods containing fewer and smaller nestlings. Early nestling survival decreases over the breeding season, particularly in urban populations. However, the diets of urban and rural nestlings are similar and do not explain differences in body condition.

Summary: This study evaluated nanoparticle (NP) formulations for protecting Steinernema carpocapsae infective juveniles (IJs) from UV radiation. The results showed that silica-NH2 NPs had adverse effects on IJ viability after UV radiation, while titania-NH2 NPs provided the highest UV protection. The anti-UV capability of titania-NH2 NPs has promise as a tool to enhance biocontrol efficacy of EPNs under field conditions.

Summary: This study found that frozen and refrigerated H. halys egg masses were more prone to parasitism compared to fresh ones, both in lab and field experiments. Furthermore, natural H. halys egg masses showed higher parasitism and lower predation compared to sentinel egg masses in soybean fields. This suggests that collecting natural egg masses is the most effective method for assessing parasitism in the field.

Summary: The study evaluated the resistance to eight commonly used insecticides in eight different populations of onion thrips collected from different regions in Punjab, Pakistan. The populations showed varying levels of resistance, with the highest resistance observed in deltamethrin. Spinosyns were found to be effective and could be used as alternatives for thrips control in onion fields.

Summary: The recent study focused on the spatiotemporal distribution of stink bugs and their natural enemies across farmscapes. However, little attention has been given to the impact of plant height on vertical stratification of stink bugs and their natural enemies in diverse habitats. This study investigated the capture of different stink bug species and a predaceous wasp in different habitats and at varying heights, and evaluated the effects of canopy height and habitat on stink bug egg mass predation and parasitism.

Summary: This study measured the density of stink bug species and patterns of parasitism and predation in agricultural crops. The results showed that the exotic Halyomorpha halys and Nezara viridula were the dominant stink bug species observed. H. halys was first detected on trees, followed by corn, cotton, and soybean, while N. viridula had higher captures in corn and cotton. Conservation biological control has the potential to enhance parasitism in field crop agroecosystems.

Summary: Rising global temperatures lead to emerging pests, frequent insecticide applications, and disruption of biological control, potentially exacerbating outbreaks of new pests. Whiteflies were detected earlier and in greater numbers in areas with more widespread pesticide use and warmer temperatures, while also moving between regions due to differences in crop types.

Summary: This study aimed to investigate the distribution and seasonal dynamics of aphids infesting cotton fields in the southern United States where cotton leafroll dwarf virus (CLRDV) has been reported. The most common aphid species on cotton were Aphis gossypii and Protaphis middletonii, while other species had consistently low populations. These findings provide valuable information on the seasonal variation of cotton-infesting aphid species and populations in the region.

Summary: The study found that three bird species, including Northern cardinal (Cardinalis cardinalisis), Tufted titmouse (Baeolophus bicolor), and Carolina wren (Thryothorus ludovicianus), consumed brown marmorated stink bugs (Halyomorpha halys), and their DNA was detected in avian fecal samples using PCR. However, the low level of brown marmorated stink bug DNA may be due to the short retention time of prey in birds.

Summary: Compared with commercial strains, Cordyceps javanica Wf GA17, a causing agent of whitefly epizootics in southern Georgia, demonstrated superior temperature tolerance and higher virulence against the whitefly Bemisia tabaci in laboratory experiments. However, in a two-year field study, the post-application persistence and efficacy of this fungus did not perform well compared to the commercially available C. javanica Apopka97 strain when applied alone. JMS stylet oil was found to enhance the efficacy and persistence of both strains.
