Honeybees (Apis mellifera) as pollinators are of economic and ecological importance to global agriculture natural ecosystems. However, honeybees being threatened by highly effective pesticides such neonicotinoids, which can have detrimental impacts on honeybee foraging in particular. In a colony, nectar pollen foragers play distinct roles sustaining the colony. Despite evidence sub-lethal effects neonicotinoids individual honeybees, little is known about how affect behaviour an entire Here, we conducted field study using our innovative artificial intelligence (AI)-based automated monitoring technology investigate neonicotinoid imidacloprid at field-realistic doses colony behaviour. A mechanistic simulation model (BEEHAVE) was then used reproduce interpret observations, further identify plausible mechanisms underlying empirical findings. Surprisingly, revealed that greatly reduced but not foraging. addition, no lethal were observed. The simulations showed time spent completing their trips significantly increased, subsequently decreased number per day, thereby reducing level. This suggests may require different energetic costs, cognitive functions, and/or gene expressions, implies susceptibilities chemical stressors. As essential for brood rearing, exposure concentrations together with other stressors, survival resilience more than previously thought.

Acetamiprid is a neonicotinoid insecticide used in crop protection worldwide. Such widespread application can pose risks to pollinator insects, particularly honeybees (Apis mellifera); therefore, the evaluation of harmful effects acetamiprid necessary. Recent studies report behavior and gene expression dysfunction honeybees, related contamination. However, most do not consider potential metabolism disorders. To examine sublethal doses on hemolymph worker bee larvae(2 days old) were fed with sucrose water containing different concentrations (0, 5, 25 mg/L) until capped (6 old). The (200 μL) freshly larvae was collected for liquid chromatography-mass spectrometry (LC-MS). Overall, increasing exposure induced greater metabolic variations larvae(treated groups compared untreated). In positive ion mode, 36 common differential metabolites acetamiprid-treated screened from identified metabolites. Of these, 19 upregulated, 17 downregulated. 10 negative mode. 3 7 These included traumatic acid, indole etc. commonly differentiated classified as compounds biological roles, lipids, phytochemical compounds, others. pathways significant differences (P < 0.05) tryptophan, purines, phenylalanine, As concentration increased, content acid tryptophan metabolite l-kynurenine decreased, lipids also decreased. Our results revealed that damage honeybee increased when solution formulations residue their food had higher than 5 mg/L, causing disorders various substances larvae. Analysis these processes provide theoretical basis further research elucidate detoxification mechanisms.

In the global apiculture industry, reward feeding and supplementary are essential for maintaining bee colonies. Beekeepers provide artificial supplements to their colonies, typically in form of either a honey–water solution or sugar syrup. Owing cost considerations associated with beekeeping, most beekeepers opt However, effects different types on colonies subsequent impact honey composition remain unclear. To address this gap, study compared chemical composition, antioxidant capacity, nutritional potency three honey: derived from fed syrup (sugar-based product, SP) (honey-sourced honey, HH) naturally sourced (flower-sourced FH), which served as control. The results revealed that FH outperformed HH SP terms total acidity, content, protein SP. Regarding efficacy, including lifespan learning memory capabilities worker bees, exhibited best outcomes, no significant differences observed between This underscores importance source selection influencing quality emphasizes potential consequences substituting traditional practices.

Flumethrin is a widely used acaricide, but its improper use often leads to residue accumulation in honeybee colonies, thus threatening the health of honeybees, especially at larval stage. Therefore, this study aimed describe direct toxicity flumethrin on (Apis mellifera) larvae by conducting bioassays for immune and detoxification-related enzymes transcriptome sequencing determine potential effects newly emerged adults who were exposed during Results showed that higher concentration to, greater damage physiology worker bees. When concentrations than 0.01 mg/L, activities glutathione sulfur transferase carboxylesterase affected, metabolism-related genes head honeybees stage down-regulated. 0.1 mg/L significantly increased mixed-functional oxidase content larvae, reduced survival rate, down-regulated expression levels olfactory-related antioxidant-related honeybees.
