Agricultural insect pests (AIPs) are widely successful in adapting to natural and anthropogenic stressors, repeatedly overcoming population bottlenecks acquiring resistance intensive management practices. Although they have been largely overlooked evolutionary studies, AIPs ideal systems for understanding rapid adaptation under novel environmental conditions. Researchers identified several genomic mechanisms that likely contribute adaptive stress responses, including positive selection on de novo mutations, polygenic standing allelic variation phenotypic plasticity (e.g., hormesis). However, new theory suggests itself may induce epigenetic modifications, which confer heritable physiological changes (i.e., stress-resistant phenotypes). In this perspective, we discuss how from agricultural generates the genetic modifications associated with AIPs. We summarise existing evidence stress-induced processes context of insecticide resistance. Ultimately, propose studying offers opportunities resources advancing our knowledge evolution.

Abstract In agroecosystems, insects contend with chemical insecticides often encountered at sublethal concentrations. Insects’ exposure to these mild stresses may induce hormetic effects, which has consequences for managing insect pests. this study, we used an electrical penetration graph (EPG) technique investigate the feeding behavior and age-stage, two-sex life table approach estimate effects of thiamethoxam on greenbug, Schizaphis graminum . The LC 5 10 significantly decreased longevity fecundity directly exposed adult aphids (F 0 ). However, longevity, fecundity, reproductive days (RP d )—indicating number in females produce offspring – progeny generation 1 ) exhibited significant increase when parental were treated active ingredient. Subsequently, key demographic parameters such as intrinsic rate ( r net R increased treatment. EPG recordings showed that total durations non-probing (Np), intercellular stylet pathway (C), salivary secretion into sieve element (E1) increased, while mean duration probing (Pr) phloem sap ingestion concurrent salivation (E2) F adults Interestingly, generation, Np was E2 Taken together, our results LC5 induces intergenerational individuals S. These findings have important implications control against highlight need a deeper understanding ecological exposures within pest management strategies across agricultural landscapes.

The neonicotinoid acetamiprid reduces larval and adult survival in honeybees (Apis mellifera) and interacts with a fungicide mixture

Plant protection products (PPPs), which are frequently used in agriculture, can be major stressors for honeybees. They have been found abundantly the beehive, particularly pollen. Few studies analysed effects on honeybee larvae, and little is known about of insecticide-fungicide-mixtures, although this a highly realistic exposure scenario. We asked whether combination insecticide fungicides would affect developing bees. Honeybee larvae (Apis mellifera carnica) were reared vitro larval diets containing different PPPs at two concentrations, derived from residues neonicotinoid acetamiprid, combined boscalid/dimoxystrobin mixture all three substances. Mortality was assessed larval, pupal, adult stages, size weight newly emerged bees measured. The treatment higher concentrations significantly reduced survival. Interestingly, survival not affected by high concentrated insecticide-fungicides-mixture. However, negative synergistic caused low insecticide-fungicides-mixture, had no effect when applied alone. lower led to lighter bees, unaffected. Our results suggest that environmental relevant harmful To fully understand interaction PPPs, more combinations should studied social solitary with possibly sensitivities.

Hormetic response to pesticides in diapausing bees

Biology Letters, Год журнала: 2025, Номер 21(1)

Pollinators face declines and diversity loss associated with multiple stressors, particularly pesticides. Most pollination services are provided by annual bees that undergo winter diapause, many common pesticides highly soluble in water move through soil plants where hibernate feed, yet the effects of on pollinators’ diapause survival performance poorly understood. Pesticides may have complex bees, some were shown to induce hormetic various traits characterized high-dose inhibition coupled low-dose stimulation. Here, we examined occurrence hormesis responses imidacloprid. We found while longevity reproduction reduced following exposure imidacloprid, length new queens (gynes) was greater. Diapause is a critical period life cycle most profound their health. Exposure sublethal doses increase bees’ resistance stress/cold during but also trade off reproductive later life. Identifying these trade-offs crucial understanding how stressors affect pollinator health should be accounted for when assessing pesticide risk, designing studies facilitating conservation management tools supporting diapause.
