Abstract
The global decline of bees has raised significant concerns due to their crucial role in agroecosystems, rendering their diminishment a potential predisposing factor for a worldwide crisis in the agri-food sector and ecosystems. The use of pesticides, such as neonicotinoids, can impact non-target organisms, including bees. This study aimed to evaluate the gene expression in the heads of Apis mellifera bees in the forager phase. The analysis was conducted by examining their transcriptome to assess the effects of the neonicotinoid imidacloprid through contact bioassays, administered at both lethal and sublethal doses. The results revealed differential gene expression after 1 and 4 h of imidacloprid exposure. Differentially expressed genes were categorized based on gene ontology, revealing alterations in critical biological processes, molecular functions, and cellular components. These changes were associated with immune response, stress, neurotoxicity, and other vital functions. The study highlights the importance of considering sublethal pesticide effects and their potential long-term consequences on bee populations and ecosystem functioning.
期刊介绍：
Apidologie is a peer-reviewed journal devoted to the biology of insects belonging to the superfamily Apoidea.
Its range of coverage includes behavior, ecology, pollination, genetics, physiology, systematics, toxicology and pathology. Also accepted are papers on the rearing, exploitation and practical use of Apoidea and their products, as far as they make a clear contribution to the understanding of bee biology.
Apidologie is an official publication of the Institut National de la Recherche Agronomique (INRA) and Deutscher Imkerbund E.V. (D.I.B.)
