Summary: The CDC Bottle Bioassay is a cost-effective method for screening field-caught mosquitoes against insecticidal active ingredients, with nutritional status and hydration level of mosquitoes before insecticide exposure being important experimental variables. Starvation for 24 or 48 hours decreased permethrin and malathion mean survival time, and water-only-fed mosquitoes were the most insecticide tolerant among the tested nutritional challenges.

Summary: Sensitivity to insecticides in grape berry moth populations in southwest Michigan vineyards is highly variable between different farms and across years. Continued monitoring of sensitivity and development of alternative control strategies are needed to maintain pest susceptibility to insecticides in vineyards.

Summary: Vinegar flies are important vectors of pathogens causing fruit rots of grapes. A study in Michigan found that populations of these flies have developed varying levels of resistance to insecticides from different chemical classes. This highlights the need to implement integrated sour rot management approaches that are less dependent on insecticides.

Summary: The study investigated the use of rotation with insecticides of multiple modes of action as a strategy to manage resistance in the Asian citrus psyllid. Results showed that high levels of resistance developed after three to four consecutive neonicotinoid sprays, but rotating modes of action effectively managed thiamethoxam resistance.

Summary: The study found that the overexpression of the CYP6ER1 gene played a key role in imidacloprid resistance in the brown planthopper. Two simple and convenient PCR-based molecular diagnostic methods were established to detect the CYP6ER1 gene with a three-nucleotide deletion, showing a relationship between imidacloprid resistance and the CYP6ER1 gene locus.

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: This study evaluated the susceptibility of different thrips species to spinetoram in 12 geographical areas across China, revealing variations in susceptibility to the insecticide both among species and among different regions. The results indicated field-evolved resistance in some thrips populations, with implications for management strategies and insights into thrips displacement in fields.

Summary: The susceptibility of fall armyworm populations to chlorantraniliprole in sweet corn fields in southern Florida between 2017 and 2019 varied to a small extent, with approximately fourfold differences in LC50 and LC90 values. These field populations showed reduced susceptibility compared to a reference laboratory population. However, field experiments demonstrated that foliar applications of chlorantraniliprole effectively reduced injury and infestations by fall armyworm in sweet corn fields, comparable to or lower than other insecticides. Therefore, there is currently no evidence of practical resistance to chlorantraniliprole in fall armyworm infesting Florida sweet corn fields.

Summary: Insecticide resistance surveillance is essential for effective vector control. This study compared different insecticide susceptibility bioassays and found that the topical application bioassay had the highest power to differentiate between resistant and susceptible populations, followed by the WHO tube test. The CDC bottle bioassay had the lowest power and highest variation. These findings have significant implications for interpreting surveillance results.

Summary: The study found that dual inhibition of xenobiotic pumps and cytochromes has a synergistic effect with ivermectin, greatly increasing mosquito mortality. Inhibition of xenobiotic pumps alone had no effect on ivermectin-induced mortality. Induction of xenobiotic pumps and cytochromes may confer partial protection from ivermectin.

Summary: Gill's mealybug, a major pest of pistachio in California, has shown control failures after field applications of recommended insecticides. This study developed a method to monitor the susceptibility of the mealybug to acetamiprid and found variations in susceptibility levels among populations. The resistance identified suggests the need for effective management strategies to prevent further increase in resistance levels.

Summary: Pesticide resistance in arthropod vectors of disease agents is a growing global issue. NEVBD initiated a monitoring program to detect resistant mosquito populations in the northeastern United States, with findings indicating widespread low-level methoprene resistance in Cx. pipiens. Results also highlighted the need for increased pesticide resistance testing and guidance for a centralized testing program.

Summary: In this study, it was found that inhibiting the activity of UGT enzyme effectively increased the toxicity of chlorpyrifos to the chlorpyrifos-resistant strain of Nilaparvata lugens. The resistant strain showed higher content of UGT compared to the susceptible strain. Four UGT genes (UGT386H2, UGT386J2, UGT386N2, and UGT386P1) were significantly overexpressed in the resistant strain and could be induced by chlorpyrifos. Knockdown of UGT386H2 or UGT386P1 increased the susceptibility of the resistant strain to chlorpyrifos. These findings suggest that overexpression of these two UGT genes contributes to chlorpyrifos resistance in N. lugens.

Summary: This study investigated the efficacy of insecticides on adult whiteflies in the field and laboratory conditions. Fast-acting insecticides were found to be more effective in controlling whitefly adults, and bioassays were proven to be efficient in determining efficacy prior to field applications. These findings are valuable for farmers and researchers seeking to optimize control strategies for whiteflies.

Summary: The Neotropical brown stink bug is a major soybean pest in Brazil, controlled mainly by insecticides of the neonicotinoid class. A new ingestion bioassay method using liquid diet encapsulation shows promise for detecting and monitoring resistance of E. heros populations to these insecticides. High variations in susceptibility to insecticides were detected among populations, motivating the development of diagnostic concentrations based on LC99 levels.

Summary: Tetranychus urticae Koch has become dominant in Australian cotton due to its resistance, with abamectin resistance increasing in recent years possibly due to prophylactic use. The reduction in insecticide spraying with the introduction of transgenic cotton may have led to an increase in Tetranychus lambi, despite T. urticae still being resistant.

Summary: The fall armyworm has been detected in Australia, leading to the development of a real-time PCR diagnostic assay for identifying the species and detecting mutations related to insecticide resistance. Common mutations associated with carbamate and organophosphate resistance were found in the populations tested, suggesting that the original migrated moths may have carried these mutations from outside Australia. Monitoring the resistance status of Australian fall armyworm is important, as well as considering pesticide resistance in pest management decisions.
