Summary: The sweet potato whitefly is a significant insect pest that transmits numerous plant viruses and causes damage to cotton and Solanaceae vegetables. This study found that miRNA miR-276-3p can regulate the resistance of B. tabaci to the insecticide cyantraniliprole by targeting the gene CYP6CX3. Additionally, exposure to cyantraniliprole led to the downregulation of genes associated with miRNA biogenesis. These findings enhance our understanding of the role of miRNAs in P450 regulation and cyantraniliprole resistance in B. tabaci.

Summary: Cyantraniliprole is a diamide insecticide with broad-spectrum activity, targeting ryanodine receptors and disrupting Ca2+ homeostasis in insects. This study revealed the crucial role of calmodulin (CaM) in the stress response of the whitefly to cyantraniliprole, showing that overexpression of BtCaM can enhance tolerance to the insecticide and regulate intracellular Ca2+ levels. These findings may provide insights into a universal insect response to diamide insecticides.

Summary: Bemisia tabaci, or the tobacco whitefly, is a major agricultural pest that causes significant damage to crops worldwide. In China, this pest has developed resistance to commonly used insecticides, leading to the increased use of cyantraniliprole as an alternative. The overexpression of the CYP4G68 gene was found to confer cyantraniliprole resistance in a lab-selected resistant strain. Field-sampled populations across China also showed varying levels of resistance to cyantraniliprole, with CYP4G68 overexpression identified as a significant factor in the resistance development in two populations.

Summary: In this study, we investigated the role of CYP6CX2 and CYP6CX3 in mediating whitefly thiamethoxam resistance. Our results showed that the mRNA levels of these two genes were up-regulated after exposure to thiamethoxam. Transcriptional levels were overexpressed in resistant strains and positively correlated with resistance levels. Silencing these genes increased whitefly susceptibility to thiamethoxam. These findings provide insights into the role of cytochrome P450 monooxygenases in neonicotinoid resistance and suggest their potential as target genes for pest management.

Summary: Two invasive whitefly biotypes, MEAM1 (B) and MED (Q), with higher pesticide resistance levels, have been found in China. Recent studies have identified metabolic resistance mechanisms and target site mutations in these populations, which render them resistant to a range of insecticides. Novel pest control agents, such as RNA-based pesticides and nano-pesticides, show promise for future field control of these invasive whiteflies.

Summary: This study investigated the resistance of Bemisia tabaci populations in different regions of China. The results showed an increasing trend of resistance to certain insecticides in B. tabaci over the past few years. The findings provide basic data for integrated pest management and insecticide resistance management of B. tabaci in China.

Summary: This study assessed the fitness costs and mode of inheritance associated with resistance to flupyradifurone in B. tabaci. It found that the resistance had varying degrees of dominance and resulted in fitness costs for the resistant populations. These findings provide valuable knowledge for formulating pest management strategies in vegetable production.

Summary: The whitefly has developed high metabolic resistance to most neonicotinoids, and UGT353G2 may be involved in this resistance. UGT inhibitors enhance the toxic damage of neonicotinoids to the whitefly, while RNA interference increases the sensitivity of the whitefly to neonicotinoids.

Summary: Insect vectors and insect-borne plant viruses pose a serious threat to agricultural production. Insecticides are commonly used to prevent the transmission of insect-borne viruses. However, the relationship between insect vector resistance and arboviruses has not been extensively studied. This study explores the effect of Tomato chlorosis virus (ToCV) on the insecticide resistance of Bemisia tabaci MED. The results show that ToCV infection upregulates detoxification-related genes and increases the activity of detoxification enzymes in B. tabaci, leading to reduced sensitivity to certain insecticides.

Summary: The tobacco whitefly, Bemisia tabaci, is a polyphagous crop pest that causes significant economic damage worldwide. Neonicotinoids are commonly used insecticides for the control of this species. Understanding the mechanisms responsible for resistance to neonicotinoids in B. tabaci is crucial for effective control and damage limitation. This study reveals that qualitative changes in the cytochrome P450 gene CYP6CM1 alter its metabolic capacity and enhance detoxification of neonicotinoids.

Summary: Insect TRPV, a subfamily of TRP channels, is the target of afidopyropen in some sucking insect pests. Our study showed that the over-expression of the TRPV Nan gene is responsible for the development of afidopyropen resistance in B. tabaci. This finding provides new insights into the function of TRPVs in pesticide resistance and suggests potential strategies for pest management.

Summary: Measurements of experimental errors between bioassays and field response of insecticide were investigated using parallel sample populations. The bioassays were more precise in measuring insecticide efficacy compared to field trials. Identifying and considering external confounding factors are important when estimating insecticide efficacy or predicting field response through bioassays.

Summary: Bemisia tabaci, a significant agricultural pest in Australia, has developed resistance to pyriproxyfen, spirotetramat, and buprofezin. The resistance levels vary among populations and regions. The addition of buprofezin provides a new option for managing whitefly pests and strengthening resistance management strategies.

Summary: The study found that the field-collected population of Bemisia tabaci was initially susceptible to the selected insecticides, but continuous selection for only five generations significantly increased resistance development. Different insecticides resulted in varying degrees of resistance after continuous selection, indicating the need for proper management strategies in the field.
