“…Studies on the exposure of bees during the larval stage through in vitro rearing tests also focus on this species (Aupinel et al 2007;Hendriksma et al 2011;Wilkins et al 2013;Tavares et al 2015). However, Kremen et al (2002), Del Sarto et al (2005) and Tomé et al (2015) highlighted the importance of native pollinators in the context of insecticide use in agriculture.…”

Consumption of the neonicotinoid thiamethoxam during the larval stage affects the survival and development of the stingless bee, Scaptotrigona aff. depilis

-In Brazil, where the use of neonicotinoids is allowed in bee-attracting flowering crops, we investigated whether thiamethoxam intake during the larval stage of the native bee species Scaptotrigona aff. depilis affects the survival and development by exposing larvae to contaminated food. Our results indicated that the larvae exposed to the dose at a field-realistic level and to the doses ranging around it had their survival rates significantly impaired. At the highest doses, we observed larvae and pupae with shorter and longer development times, respectively, and the formation of smaller and asymmetric specimens. Evidently, we need to consider that thiamethoxam reaches the pollen and nectar at residual levels, and that they are processed by nurse bees before destined for offspring. Nevertheless, our findings suggest a warning, since the individuals had their biological parameters affected by thiamethoxam, when exposed to doses at field-realistic levels.larval food / in vitro rearing / adverse effects / developmental stage / insecticides

“…Additional sources of variation can occur from the composition of the pesticide formulations that are used. While different amounts of solvents used for toxicology analysis can affect the readout (Wilkins et al, 2013), pesticide adjuvants (other ingredients found in pesticide formulations that are thought to be inert) can also influence pesticide toxicity (Chen et al, 2019). An emerging interest is the potential for synergistic toxicity between multiple pesticides that are applied in combination.…”

Understanding the Effects of Sublethal Pesticide Exposure on Honey Bees: A Role for Probiotics as Mediators of Environmental Stress

et al. 2020

Managed populations of the European honey bee (Apis mellifera) support the production of a global food supply. This important role in modern agriculture has rendered honey bees vulnerable to the noxious effects of anthropogenic stressors such as pesticides. Although the deleterious outcomes of lethal pesticide exposure on honey bee health and performance are apparent, the ominous role of sublethal pesticide exposure is an emerging concern as well. Here, we use a data harvesting approach to better understand the toxicological effects of pesticide exposure across the honey bee life cycle. Through compiling adult-and larval-specific median lethal dose (LD 50) values from 93 published data sources, LD 50 estimates for insecticides, herbicides, acaricides, and fungicides are highly variable across studies, especially for herbicides and fungicides, which are underrepresented in the meta-data set. Alongside major discrepancies in these reported values, further examination of the compiled data suggested that LD 50 may not be an ideal metric for honey bee risk assessment. We also discuss how sublethal effects of pesticide exposure, which are not typically measured in LD 50 studies, can diminish honey bee reproduction, immunity, cognition, and overall physiological functioning, leading to suboptimal honey bee performance and population reduction. In consideration of actionable solutions to mitigate the effects of sublethal pesticide exposure, we have identified the potential for probiotic supplementation as a promising strategy that can be easily incorporated alongside current agricultural infrastructure and apicultural management practices. Probiotic supplementation is regularly employed in apiculture but the potential for evidence-based targeted approaches has not yet been fully explored within a formal toxicological context. We discuss the benefits, practical considerations, and limitations for the use and delivery of probiotics to hives. Ultimately, by subverting the sublethal effects of pesticides we can help improve the long-term survival of these critical pollinators.

“…Assim, é evidente a importância da padronização de testes que envolvam abelhas em todas as idades, para que seja possível prever os potenciais prejuízos para a colônia como um todo, bem como atingir medidas mitigadoras dos efeitos sobre abelhas. (Oomen et al, 1992;Aupinel et al, 2007a;Hendriksma et al, 2012;Wilkins et al, 2013; Pilling et al, (2013) e Carreck e Ratnieks (no prelo) afirmam que os estudos conduzidos em condições de laboratório e em casas de vegetação tem evidenciado efeitos subletais em abelhas, através da exposição dos indivíduos a doses muito superiores àquelas registradas em campo Henry et al, 2012;Schneider et al, 2012; …”

aff. depilis forager workers allowed to consider this species as bioindicator of environmental contamination. In this study, the mortality was not a conclusive parameter as to the potential adverse effects of thiamethoxam for the bees. The potential iv of Scaptotrigona aff. depilis species as bioindicator is an important step to assess environmental contamination by neonicotinoids on stingless bees, may be used for public policy.
