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. In fact, besides high induced at lower concentrations, change’s magnitude occurrence varied between temperatures depended faced females. increase from 15 °C increased 4 fivefold. Sublethal extended longevities for individuals treated with (all concentrations) 25 (LC LC 20 ) 1 ). Additionally, total during females' lifespan was , 5 10 ), results reinforce a shift studies focusing single investigating stressors’ combinations hormetic response.

Assessing the lethal effects of pesticide residue exposure on beneficial parasitoids and their host, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae)

Abstract Chemical control is currently the main strategy for managing brown marmorated stink bug, Halyomorpha halys (Stål). However, chemical pesticides can harm nontarget species, including natural enemies of H. halys. Pesticides with high toxicity to and low its parasitoids need be identified support management. This not only biological but also preemptive classical by parasitoids. Here, we assessed contact residues eight insecticides against three parasitoid species (Anastatus japonicus Ashmead (Hymenoptera: Eupelmidae), Trissolcus Scelionidae), cultratus Mayr Scelionidae)). study aims provide valuable insights using these Our results showed that A. exhibited higher tolerance tested pesticides, while T. was most sensitive species. Among chlorantraniliprole had lowest overall impact on all Additionally, acetamiprid, azadirachtin, rotenone were found harmless japonicus. Acetamiprid, however, slightly harmful cultratus.

Four Neurotoxic Insecticides Impair Partner and Host Finding in the Parasitoid Leptopilina heterotoma and Bioactive Doses Can Be Taken up Via the Host

Journal of Chemical Ecology, Journal Year: 2025, Volume and Issue: 51(1)

Published: Jan. 29, 2025

Abstract In modern agriculture, control of insect pests is achieved by using insecticides that can also have lethal and sublethal effects on beneficial non-target organisms. Here, we investigate acute toxicity four the males’ sex pheromone response female host finding ability Drosophila parasitoid Leptopilina heterotoma . The nicotinic acetylcholine receptor antagonists acetamiprid, flupyradifurone sulfoxaflor, as well acetylcholinesterase inhibitor dimethoate were applied topically acetone solutions. Males treated with all no longer preferred in a T-olfactometer. Duration wing fanning, an element pheromone-mediated male courtship behavior, was reduced insecticides. females to orientate towards host-infested feeding substrate not affected acetamiprid tested dose range. However, treatment dimethoate, sulfoxaflor resulted loss females’ preference for odor. At lowest doses interfering olfactory abilities L. this study (acetamiprid: 0.21 ng, dimethoate: 0.105 flupyradifurone: 2.1 ng sulfoxaflor: ng), ≥ 90% wasps survive insecticide treatment. Male responses disturbed those had developed D. melanogaster larvae reared dimethoate-treated medium at levels. Hence, sufficient interfere chemical orientation be taken up via food chain.

Ecological risks of a biopesticide from marine-derived amino-oligosaccharides in agriculture: Food chain effects on non-target organisms Frankliniella occidentalis and its natural predator Neoseiulus barkeri

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 292, P. 118015 - 118015

Published: March 1, 2025

A biopesticide from marine-derived amino-oligosaccharides (AO) are extensively utilized in China, yet there is a lack of scientific literature on their potential ecological risks when transmitted through the food chain to Neoseiulus barkeri, natural predator Frankliniella occidentalis. In this study, we conducted comprehensive investigation into effects AO both F. occidentalis and N. barkeri. Our findings indicate that AO-treated cucumber leaves facilitated population growth but indirectly suppressed fecundity barkeri which fed first instar nymphs Besides, ingested exhibited elevated levels total protein defense enzymes, including catalase (CAT) peroxidase (POD), whereas detoxification enzymes activity, such as carboxylesterase (CarE) cytochrome P450 monooxygenase (P450), was diminished. Conversely, decreased superoxide dismutase (SOD) POD, coupled with an CarE because transmission. conclusion, non-target organisms may involve modulation enzyme activities, leading varying fitness costs. These provide critical insights for agricultural pest management strategies, highlighting necessity evaluating within ecosystems, especially beneficial insects, during its application.
