The peach–potato aphid, Myzus persicae (Sulzer), is one of the most important pests economic crops. It damages plant directly by consuming nutrients and water indirectly transmitting viruses. This pest has unenviable title having resistance to more insecticides than any other herbivorous insect pest. Due development its chemical pesticides, it necessary find control options. Consequently, increased efforts worldwide have been undertaken develop new management approaches for M. persicae. In this review, we highlight problems associated with importance, current approaches. review also describes challenges their potential solutions, special focus given evolution insecticidal sustainable strategies, such as biocontrol agents, entomopathogens, use natural plant-derived compounds, cultural methods. Furthermore, provides some successful from above eco-friendly strategies that show high efficacy against

Behavioral resistance to insecticides: current understanding, challenges, and future directions

Current Opinion in Insect Science, Journal Year: 2024, Volume and Issue: 63, P. 101177 - 101177

Published: Feb. 13, 2024

Identifying and understanding behavioral resistance to insecticides is vital for maintaining global food security, public health, ecological balance. Behavioral has been documented occur in a multitude of insect taxa dating back the 1940s but not received significant research attention due primarily complexities studying behavior lack any clear definition resistance. In recent years, systematic effort investigate mechanism(s) pest (e.g., German cockroach house fly) have undertaken. Here, we practically define resistance, describe efforts taken by groups elucidate mechanisms, provide insight on designing appropriate bioassays investigating mechanisms future.

Abstract Insecticides remain an important tool for the control of many insect pests. There has long been interest in insecticide mixtures (in‐can and tank‐mix) as a means to provide needed efficacy and/or spectrum public health, crop pests or pest complexes.

Temperature effects on the hormetic response of Myzus persicae after sublethal exposure to insecticides

Abstract Studies on insecticide-induced stimulatory effects in pest insects have become of utmost importance due to their potential implications management. Temperature influences the physiology and biology ectothermic organisms like insects. It can also affect toxicity relative efficacy insecticides that are used agricultural fields. However, impact temperature insect responses after exposure mild stresses has frequently been overlooked. Here, we investigated how different levels (15; 20; 25; 28 °C) modulate two synthetic chlorpyrifos (organophosphate) deltamethrin pyrethroid); subsequently impacts survival reproduction green peach aphid Myzus persicae exposed sublethal concentrations insecticides. Our findings indicated temperature-dependent chemicals mortality, longevity, number nymphs produced by aphids lethal exposures.

New insights into chlorantraniliprole metabolic resistance mechanisms mediated by the striped rice borer cytochrome P450 monooxygenases: A case study of metabolic differences

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 912, P. 169229 - 169229

Published: Dec. 8, 2023

The anthranilic diamide insecticide chlorantraniliprole has been extensively applied to control Lepidoptera pests. However, its overuse leads the development of resistance and accumulation residue in environment. Four P450s (CYP6CV5, CYP9A68, CYP321F3, CYP324A12) were first found be constitutively overexpressed an SSB CAP-resistant strain. It is imperative further elucidate molecular mechanisms underlying P450s-mediated CAP for mitigating environmental contamination. Here, we heterologously expressed these four insect cells evaluated their abilities metabolize CAP. Western blotting reduced CO difference spectrum tests showed that P450 proteins had successfully Sf9 cells, which are indicative active functional enzymes. recombinant CYP6CV5, CYP324A12 exhibited a preference metabolizing fluorescent model probe substrates EC, BFC, EFC, EC with enzyme activities 0.54, 0.67, 0.57, 0.46 pmol/min/pmol P450, respectively. In vitro metabolism revealed distinct metabolic rates (0.97, 0.86, 0.75, 0.55 P450) efficiencies (0.45, 0.37, 0.30, 0.17) enzymes, thereby elucidating different protein catalytic activities. Furthermore, docking confirmed differences unveiled hydroxylation reaction generating N-demethylation methylphenyl during metabolism. Our findings not only provide new insights into at level but also demonstrate significant capacities multiple degradation facilitate evaluation mitigation toxic risks associated application

Is insecticide resistance a factor contributing to the increasing problems with Dalbulus maidis (Hemiptera: Cicadellidae) in Brazil?

Pest Management Science, Journal Year: 2024, Volume and Issue: 80(10), P. 5120 - 5130

Published: June 13, 2024

Abstract Background The corn leafhopper, Dalbulus maidis , is an important pest in Brazil. While chemical control has traditionally been the cornerstone for managing this pest, field failures have reported some insecticides. To understand if these are due to resistance, we evaluated susceptibility of 11 field‐collected populations D. major insecticides during 2021–2022 crop seasons Brazil using concentration‐mortality bioassays. Additionally, employed diagnostic concentration bioassays and foliar sprays at label‐recommended rates 8–10 collected 2022–2023 seasons. Results High methomyl, carbosulfan acephate was observed on across all tested with resistance ratio (RR) based LC 50 <10‐fold, except one population from Bahia State that exhibited reduced methomyl (RR = 17.5). On other hand, bifenthrin, acetamiprid, imidacloprid, RR ranging 90 2000‐fold. This neonicotinoid pyrethroid further confirmed concentrations 99 susceptible strain, survival >20% mortality <80%. Most exposed low (<5%) high (>80%). Conclusions likely explain controlling study represents first large‐scale monitoring insecticides, results will contribute decision‐making regarding management pest. © 2024 Society Chemical Industry.
