Insecticide resistance is a great challenge facing mosquito operational control agencies across the United States, where few active ingredients with unique modes of action are available for use, increasing resistance pressure and further hampering resistance management strategies. Emergence and expansion of insecticide resistance in mosquitoes can be detected by resistance monitoring programs; however, there are gaps in our knowledge regarding the link between resistance bioassay results and operational control outcomes. Here, we review both public health and agricultural studies on pesticide resistance bioassays and control outcomes. A discussion on the main gaps in our knowledge of insecticide resistance and a review of resistance management practices is also presented. We conclude with research questions that can advance our understanding of resistance monitoring and control.

The ectoparasitic mite Varroa destructor remains a great threat for the beekeeping industry, for example contributing to excessive winter colony loss in Canada. For decades, beekeepers have sequentially used the registered synthetic varroacides tau-fluvalinate, coumaphos, amitraz, and flumethrin, leading to the risk of resistance evolution in the mites. In addition to the widespread resistance to coumaphos and pyrethroids, a decline in amitraz efficacy has recently been reported in numerous beekeeping regions in Canada.

Western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae) is an invasive agricultural pest with developed resistance to abamectin in some strains due to frequent treatment with the pesticide. In this study, we examined differentially expressed proteins (DEPs) between abamectin-resistant (Aba; under abamectin selective pressure) and susceptible strains (Aba; without abamectin selective pressure) of F. occidentalis.

Hygienic insecticides are applied directly to the living environment and are closely related to human life. Dimefluthrin (DIM) is one of the most widely used hygienic insecticides globally. However, with increasing mosquito resistance, both the concentration and duration of DIM usage have risen, prompting public concerns regarding its neurotoxic risks, especially for immunocompromised children.

With their diverse species, mosquitoes are known to transmit the causal agents of diseases such as malaria, dengue, and yellow fever. Their high adaptability, attraction to humans, and variable adult behaviors make them a significant health concern. The focus on Aedes aegypti is significant for reducing vector-human contacts, monitoring insecticide resistance, and developing innovative vector management strategies.
