Acute toxicity of imidacloprid to the aquatic invertebrate

Neonicotinoids are used for fast-acting veterinary and crop protection. Their selective target is insect nicotinic acetylcholine receptor. This selectivity is important to minimize undesired effects on humans, despite its unwanted action on non-target species and possible cumulative effects on freshwater biota. Although imidacloprid (IMI) is an insecticide, there is evidence that at higher concentrations it may be harmful to plants and algae. A preliminary testing of pure compound IMI and its commercial formulation Confidor 200SL (Bayer Crop Science) was performed on freshwater algae Scenedesmus subspicatus, before proceeding with further testing on aquatic invertebrates. Consequently, we have explored the baseline toxicity of these compounds on biochemical responses of non-target bioindicator species such as Gammarus fossarum (Amphipoda, Crustacea).
