“…Honey bees are typically exposed to a cocktail of residues; in-hive (beekeeper applied) acaricides and other veterinary drugs applied over long-time periods and out-of-hive (farmer applied) pesticides encountered in pollen, nectar, and water during their foraging activity (Bogdanov, 2006;Chauzat et al, 2011;Rortais et al, 2005). These pesticide residue mixtures may act alone or in interaction (Carnesecchi et al, 2019), in ways currently difficult to predict, potentially creating a toxic environment for honey bee growth and development (Tomé et al, 2020;Yao et al, 2018;Zhu et al, 2014).…”

Pesticide and veterinary drug residues are one of the stress factors affecting bee health and mortality. To investigate the occurrence, the concentration and the toxicity risk to bees of pesticide residues in four different types of beeswax (brood comb wax, recycled comb wax, honey comb wax, and cappings wax), 182 samples were collected from apiaries located all over the Belgian territories, during spring 2016 and analysed by LC-MS/MS and GC-MS/MS for the presence of 294 chemical residues. The toxicity risk to bees expressed as the Hazard Quotient (HQ) was calculated for each wax sample, according to two scenarios with different tau-fluvalinate LD 50 values. Residues showing the highest prevalence were correlated to bee mortality in a multivariate logistic regression model and a risk-based model was used to predict colony bee mortality. Altogether, 54 different pesticide and veterinary drug residues were found in the four types of beeswax. The residues with a higher likelihood to be retained in beeswax are applied in-hive or with a high lipophilic nature. The multivariate logistic regression model showed a statistically significant influence of chlorfenvinphos on bee mortality. All our results indicated that cappings wax was substantially less contaminated. This national survey on beeswax contamination provides guidelines on the re-use of beeswax by beekeepers and shows the necessity to introduce maximum residue levels

“…For these reasons, OCs accumulate and bio-accumulate in foodstuff, representing a matter of concern for the consumer [2]. Organophosphates can induce acute poisoning via food consumption due to their acetylcholinesterase inhibition activity, representing a life-threatening concern [15,16]. This class of pesticides, widely used in agriculture to protect against crop-eating insects and to control Varroa destructor, represents a consistent contamination source [17,18].…”

Monitoring contaminant residues in honey helps to avoid risks to human health, as it is a natural product widely consumed in all population groups, including the most vulnerable, such as children and the elderly. This is important for organic honey production that may be negatively influenced by geographical area pollution. Considering the importance of collecting data on the occurrence of various xenobiotics in different geographical areas, this study aimed to investigate the presence of contaminant residues (persistent organic pollutants (POPs) and pesticides, including glyphosate and metabolites) in organic honey samples from different production areas using different analytical methods, in order to confirm their incidence and possible impact on the food safety traits of organic production. Regarding POPs, traces of benzofluoroanthene and chrysene were detected in honey from intensive orchards and arable lands. Traces of all polychlorobiphenyl (PCB) congeners were detected at different percentages in almost all of the samples, regardless of the origin area. Traces of polybromodiphenylethers (PBDE 28, 33, and 47) were found in different percentages of samples from all of the geographical areas examined. Traces of organochlorines (OCs) and organophosphates (OPs) were identified in honey samples belonging to all of the geographical areas. No glyphosate, glufosinate, and aminomethylphosphonic acid (AMPA) residues were detected.

“…Previous studies demonstrated that adults exposed to pesticides upregulate detoxification genes [37,39,40]. Tomé and coworkers found that multiple genes were upregulated in the newly emerged adults exposed to GLY and other agrochemicals, even though pesticide exposure occurred almost two weeks earlier during the larval stage of development [79]. On the contrary, they observed the downregulation of detoxification genes during larval exposure.…”

“…In our study, we observed some similar tendencies in the regulation of detoxification pathways in larvae and young workers taken from inside colonies situated in an agricultural landscape. The downregulation of detoxification genes during the larval stage might relate to other disorders, such as low survival, poor regulation of development and various morphological disorders [79]. Additionally, enhanced catabolism and oxidative metabolism were found in honeybee larvae reared in vitro because of the sub-lethal exposure to GLY, even in the absence of observable symptoms [36].…”

“…Furthermore, the environmental stress after post-emergence weed control has an impact on the detoxification pathways in larvae, independently of the beehives' surroundings. However, the energetic cost of development combined with social protection through colony-level buffering mechanisms may explain the differences in gene expression patterns between exposed larvae and adults [79].…”

The honeybee Apis mellifera is exposed to agricultural intensification, which leads to an improved reliance upon pesticide use and the reduction of floral diversity. In the present study, we assess the changes in the colony activity and the expression profile of genes involved in xenobiotic detoxification in larvae and adult honeybees from three apiaries located in agricultural environments that differ in their proportion of the crop/wild flora. We evaluated these variables before and after the administration of a mixture of three herbicides during the summer season. The expression of several cytochrome P450 monooxygenases decreased significantly in larvae after post-emergence weed control and showed significant differences between apiaries in the case of honeybee workers. Principal component analysis (PCA) revealed that colonies located in the plot near to a wetland area exhibited a different relative gene expression profile after herbicide application compared with the other plots. Moreover, we found significant positive correlations between pollen collection and the pesticide detoxification genes that discriminated between plots in the PCA. Our results suggest that nutrition may modify herbicide impact on honeybees and that larvae are more harmed than adults in agroecosystems, a factor that will alter the colonies’ population growth at the end of the blooming period.
