Summary: The research highlights the differential toxicity of neonicotinoid insecticides to freshwater insects, with imidacloprid showing higher toxicity. This implies a need for stricter regulation to control its use. Furthermore, the study suggests that neonicotinoid mixtures may deviate from additive toxicity and exhibit complex interactions.

Summary: Sogatella furcifera in Sichuan, China has developed high resistance to the pesticide pymetrozine, with the JL21 population showing the highest resistance level. The JL21 population also exhibited cross-resistance to triflumezopyrim and dinotefuran but remained sensitive to other pesticides. The overexpression of the CYP6FJ3 gene was found to be involved in pymetrozine resistance through hydroxylation.

Summary: This study investigates the sublethal effects of imidacloprid and sulfoxaflor on the feeding behavior of the brown planthopper (BPH) and white-backed planthopper (WBPH). The results show that these insecticides can inhibit the phloem feeding and decrease the reproduction longevity of the planthoppers. It is also found that the effectiveness of the insecticides varies between different insect pest species.

Summary: The white-backed planthopper Sogatella furcifera has developed high resistance levels to chlorpyrifos and thiamethoxam in different areas of Sichuan Province, while showing sensitivity or low resistance levels to imidacloprid and buprofezin. The overexpression of the P450 gene CYP6ER4 may contribute to the development of chlorpyrifos resistance in S. furcifera, as indicated by gene expression analysis and RNA interference experiments.

Summary: Resistance to insecticides used to control mosquitoes is likely to develop over time. Monitoring and using alternative insecticide classes are important to sustain the intervention's effectiveness. This study introduces a method for detecting resistance against orally ingested insecticides and suggests using different methods for different modes of uptake. Attractive Toxic Sugar Baits (ATSBs) show promise in controlling resistant mosquitoes, but more research is needed. Monitoring for resistance is crucial, and this study provides a potential method for detection.

Summary: The study confirmed the relationship between nitenpyram resistance and overexpression of key metabolic enzyme genes CYP6ER1 and CarE1 in Nilaparvata lugens, and highlighted the importance of miRNAs in nitenpyram resistance. Global screening identified known and novel miRNAs associated with nitenpyram resistance, with two miRNAs (novel_85 and novel_191) targeting CYP6ER1 and CarE1, respectively, demonstrating their regulatory role in insecticide resistance. Modulating the expression of these miRNAs significantly altered nitenpyram susceptibility in N. lugens, suggesting their potential as new targets in insecticide resistance management.

Summary: This study investigated the dynamic changes in bacteria and fungi in different developmental stages of the insect pest Nilaparvata lugens, revealing higher microbial diversity in eggs and mated adults compared to nymphs and unmated adults. It also found a strong correlation between fungal and bacterial alpha-diversity, suggesting a collaborative relationship between fungi and bacteria during the entire developmental period. The predominant bacterial and fungal taxa were identified, and the conservation of bacteria was greater than that of fungi during the transmission of the microbiota between developmental stages. The study highlights the potential value of further exploring microbial functions during different developmental stages and developing new pest management strategies.

Summary: Microbiome-mediated insecticide resistance in insect pests is influenced by host genotype, environmental factors, and the abundance of core bacterial symbionts. The expression of detoxifying genes in the host is correlated with the abundance of these symbionts and insecticide susceptibility levels. Moreover, environmental abiotic factors like temperature and precipitation can also predict symbiont abundance and insecticide susceptibility. These findings have implications for developing targeted microbial-based strategies to manage insecticide resistance in the field.

Summary: This study determined the susceptibility of 15 field populations of Aphis gossypii in Central China to six chemical insecticides and explored the potential resistance mechanisms of these populations. The results showed that most populations have evolved varying degrees of resistance to imidacloprid, thiamethoxam, flonicamid, and pirimicarb. However, they remained susceptible to chlorpyrifos, and showed low to moderate levels of resistance to ?-cyhalothrin. Correlation analysis revealed that the enzyme activity of cytochrome P450 and carboxylesterase were associated with the resistance to certain insecticides. Additionally, multiple resistance-associated target site mutations were detected in the field populations. These findings provide important information for understanding insecticide resistance in China and designing effective strategies for managing A. gossypii.

Summary: This study found that several fungicides have insecticidal activity against Nilaparvata lugens, with tebuconazole having the highest activity. Furthermore, tebuconazole significantly inhibited the expression of certain genes and affected the diversity and function of symbiotic fungi in N. lugens. These findings illustrate the insecticidal mechanism of tebuconazole and provide important rationale for delaying insecticide resistance.

Summary: In this study, the sublethal effects of acetamiprid and afidopyropen on Harmonia axyridis were evaluated through transcriptomics analysis. The results showed that sublethal concentrations of acetamiprid significantly reduced the reproductive capacity and lifespan of adult H. axyridis, while afidopyropen had limited effects. Additionally, both insecticides decreased H. axyridis predation. Transcriptome sequencing analysis revealed differential expression of detoxifying genes in response to acetamiprid and afidopyropen exposure. These findings highlight the importance of evaluating sublethal effects to protect and utilize natural enemies and guide pesticide use in the field.
