Insights into insecticide-resistance mechanisms in invasive species: Challenges and control strategies

Frontiers in Physiology, Journal Year: 2023, Volume and Issue: 13

Published: Jan. 9, 2023

Threatening the global community is a wide variety of potential threats, most notably invasive pest species. Invasive species are non-native organisms that humans have either accidentally or intentionally spread to new regions. One effective and first lines control strategies for controlling pests application insecticides. These toxic chemicals employed get rid pests, but they pose great risks people, animals, plants. Pesticides heavily used in managing current era. Due overuse synthetic chemicals, numerous already developed resistance. The resistance development main reason failure manage Developing pesticide management techniques necessitates thorough understanding mechanisms through which insects acquire insecticide Insects use behavioral, biochemical, physiological, genetic, metabolic methods deal with can lead continuous overexpression detoxifying enzymes. An overabundance enzymes causes resistance, pesticides rendering them ineffective against pests. A key factor amplification certain enzymes, specifically esterases, Glutathione S-transferase, Cytochromes p450 monooxygenase, hydrolyses. Additionally, insect guts offer unique habitats microbial colonization, gut bacteria may serve their hosts useful services. Most importantly, detoxification insecticides leads development. complete knowledge could be very helpful coping challenges effectively developing Integrated Pest Management particularly at lowering risk chemical environmental contaminants resulting health issues, it also ways

Multiple dsRNases Involved in Exogenous dsRNA Degradation of Fall Armyworm Spodoptera frugiperda

Frontiers in Physiology, Journal Year: 2022, Volume and Issue: 13

Published: May 5, 2022

RNAi is regarded as a promising technology for pest control. However, not all insects are sensitive to RNAi. Studies have confirmed that insect dsRNases one of key factors affecting efficiency. In the current study, we identified four genes coding from Spodoptera frugiperda genome. Spatial and temporal expression analysis showed those were highly expressed in midgut old larvae. Then delivery method was applied inducing efficient based on dsRNA encapsulated by liposome. Furthermore, assessed degradation efficiency incubation with gut juice or hemocoel characterize potential roles different SfdsRNases after suppression SfdsRNase. The result interferenced any sfdsRNase reduced exogenous midgut, interfered sfdsRNase1 sfdsRNase3 slowed down hemolymph. Our data suggest evolutionary expansion multiple high activity dsRNase would take part obstinate S. frugiperda, besides also provide an better use frugiperda.

Inhibition of transcriptional regulation of detoxification genes contributes to insecticide resistance management in Spodoptera exigua

Communications Biology, Journal Year: 2025, Volume and Issue: 8(1)

Published: Jan. 27, 2025

Abstract Synthetic insecticides have been widely used for the prevention and control of disease vectors agricultural pests. However, frequent uses resulted in development insecticide resistance these insect The adversely affects efficacy insecticides, seriously reduces lifespan insecticides. Therefore, management requires new strategies to suppress resistance. Here, we confirm that CncC/Maf are key regulators various detoxification genes involved Spodoptera exigua . Then, develop a cell screening platform identify natural compound inhibitors determine sofalcone can act as inhibitor vitro vivo. Bioassay results showed significantly enhanced toxicity (more than 3-fold) chlorpyrifos lambda-cyhalothrin against S. larvae. Finally, demonstrate greatly improve susceptibility larvae by inhibiting activity ROS/CncC-dependent detoxifying enzymes downregulating expression levels genes. be broad-spectrum synergists overcome pest populations. Altogether, our reduced resulting from suppression transcriptional regulation contributes controlling resistance, which provides very novel high-efficiency green strategy.
