Com o passar dos anos, franco desenvolvimento e evolução do sistema alimentar tem garantido acesso à alimentação básica em todo planeta a apicultura exercido papel-chave neste processo. Por conta da polinização de plantações agrícolas também fornecimento produtos derivados mel, as abelhas têm sido cada vez mais estudadas na área sistemas agroindustriais para que se garanta sobrevivência produtividade suas colônias. Atualmente um principais desafios garantir saúde das colônias é enfrentamento ectoparasita Varroa destructor. Este ácaro principal vilão melíferas ocidentais por características parasitárias, seu ciclo reprodução principalmente ser vetor transmissão diversas doenças. Os apicultores utilizam técnicas práticas redução ou erradicação ácaros, como métodos apícolas biotécnicas, acaricidas sintéticos orgânicos suaves, novos surgem acordo com abordagem escolhida tratamento. São frequentes os relatos contaminação exposição doses subletais, genética ácaros determinados acaricidas, entre outras adversidades. A continuidade estudos campo laboratoriais são determinantes quanto ao seja efetivo não produza efeitos colaterais longo curto prazo.

Beekeepers use a variety of methods to control Varroa destructor (varroa). Chemical relies heavily on flumethrin, amitraz, coumaphos, and tau-fluvalinate products. However, increasing colony losses in recent years have been linked the development resistance varroa mites these insecticides. develop mutations voltage-gated sodium channel (VGSC) that confer pyrethroids such as flumethrin. Specifically, researchers identified substitutions leucine amino acid at VGSC L925 with isoleucine, methionine, or valine. This study investigated phenotypic genotypic flumethrin populations Muğla, Türkiye. LD50 values (lethal dose for 50% mortality) were quantified, PCR sequencing used analyze gene region. The results confirmed target region all samples. Sequencing revealed 95% population carried homozygous resistant alleles, while 5% heterozygous. At locus, was replaced by isoleucine (91%), methionine (6%), valine (3%). Phenotypic assays showed an average value 49.1 µg (range: 31–61.8 µg). Comparison between susceptible not possible because no individuals identified. Despite resistance, mortality increased escalating doses, suggesting current protocols may be temporarily mitigating infestations. urgent adjustments alternative strategies are critical prevent imminent collapse.

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.

Abstract Managed honey bees are experiencing high rates of colony loss, in part due to widespread exposure agrochemicals and other environmental toxins. The ability learn about relevant stimuli is an important skill necessary for foraging navigation, although it sometimes impaired that have been exposed toxins or stressors. Here, we review the effects anthropogenic (which divide into five major classes: insecticides, acaricides, biopesticides, agrochemicals, toxins) on learning performance European bees. We discuss general trends these studies, including neurotoxic insecticides overwhelmingly most well-studied, studies focus acute individual, adult a single toxin. Protocols field-relevant vary widely among labs, make suggestions aid standardization future studies. relevance toxicological risk assessment, concluding they valuable tools assessing sublethal behavioral Their inclusion assessment would be improvement over current procedures, which largely lethality.

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. Furthermore, 1 These findings provide comprehensive understanding response sublethal could be further investigate complex molecular mechanisms under pesticide stress.
