Laboratory approach to study toxico-pathological interactions in the honey bee Apis mellifera

Résumé

Pesticides and pathogens are two categories of environmental stressors that may contribute to the decline of honey bee populations (vanEngelsdorp and Meixner, 2010). However, if their separate impacts on the honey bee are relatively well studied, knowledge on their interactions are somewhat lacking. Pioneer studies on toxico-pathological interactions have been conducted on the association of Nosema and chronic bee paralysis virus (CBPV) with organophosphate, organochlorine and pyrethroid insecticides (Ladas, 1972; Bendahou et al., 1997). These studies focused on the acute exposure to insecticides regardless of their chronic toxicity. However, the introduction of systemic insecticides, such as phenylpyrazoles and neonicotinoids in the mid 1990's renders more relevant the studies on chronic exposures to pesticides by oral route. Since, Suchail et al. (2001) have reported a discrepancy between acute and chronic toxicity of the neonicotinoids imidacloprid and its metabolites showing a high toxicity at very low doses.
