Despite the restriction of use neonicotinoids in EU, including thiamethoxam and clothianidin, debate over their risk on honey bees has not been fully settled. This study presents results a three-year working with 180 bee colonies ten replicates. Colonies were sorted into three treatments (60 per treatment) exposed to sunflower blooms grown from seeds treated thiamethoxam, clothianidin non-treat...

Pesticide residues, when present in agricultural wastewater, constitute a potential risk for the environment and human health. Hence, focused actions their abatement are of high priority both industrial sectors national authorities. This work evaluates effectiveness photocatalytic process to decompose two frequently detected pesticides water effluents fruit industry: thiamethoxam-a neonicotinoi...

The agricultural use of neonicotinoids is increasing worldwide and poses a threat to non-target organisms. existing toxicity data that mainly focused on widely used ignores the influence environmental factors, like temperature, related climate changes, etc . To fill this gap, present study assessed temperature-dependent six at four temperatures. Briefly, fish embryo test was performed following...

We reported 1 year ago (Henry et al., 2012a) that a sublethal dose of thiamethoxam, a neonicotinoid pesticide used on some common flowering crops, reduces the ability of exposed honeybees to find their way back to the colony. More recently, Guez (2013) have raised concerns about the relevance of our study design. The obvious intention of the author was to discredit our study, both by seeking af...

Apis mellifera is a pollinator insect model in pesticide risk assessment tests for bees. However, given the economic and ecological importance of stingless bees such as Melipona scutellaris Neotropical region, well lack studies on effect insecticides these bees, toxicity should be carried out to understand whether affect both species same manner. Thus, present study quantified differential sens...
