Imidacloprid (IMI – 1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-
2-ylideneamine) is a member of a relatively new class of neuro-
active neonicotinoid insecticides which are synthetic
derivatives of nicotine. Most neonicotinoids demonstrate much
lower toxicity in mammals than insects and therefore they have almost
replaced other more toxic organophosphate and carbamate
insecticides. Within a decade, they gained a market share of about
77% (Elbert et al., 2008) and in particular IMI is nowadays one of
the largest selling insecticides worldwide and get distributed in
more than 120 countries (Shripanavar and Deshmukh, 2013).
