A abelha Apis mellifera tem sido utilizada tanto para polinização quanto produção de produtos apícolas devido a sua eficácia e ampla disponibilidade. O declínio populações abelhas reportado em vários locais como Europa Ásia uma das causas é exposição pesticidas. imidacloprido um dos inseticidas mais utilizados no mundo, pois possui toxicidade seletiva neurotoxico causa hiperexcitação paralisa. Sendo inseticida sistêmico persistente, capaz translocar pelos tecidos da planta atingir as através alimentação. Nesse contexto, o presente estudo teve objetivo avaliar os efeitos colaterais do intestino médio adultas A. corpo gorduroso larvas operárias mellifera.

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.

Imidacloprid and other neonicotinoid insecticides severely impact the performance survival of honey bees pollinators. In present study, we focused on gene expression profile newly emerged Apis mellifera queen after sublethal imidacloprid treatment during larval stage. Royal jelly containing 1 ppb was provided to larvae for 3 consecutive days (2-4 postemergence). Queen treated with showed lower capping emergence rates (35.5% 24.22%, respectively) than did control (61.68% 52.95%, respectively), indicating a high failure rate rearing associated exposure The molecular response examined next. By comparing profiles imidacloprid-treated those using DESeq2, identified 215 differentially expressed genes, 105 111 up- downregulated respectively. Gene Ontology results indicated that chitin binding- calcium ion binding-related genes were upregulated, while phototransduction- visual perception-related downregulated. mortality altered suggest even can bee survival.
