Developed to replace organophosphate and carbamate insecticides, neonics are systemic in design, transfusing into all parts of treated plants, including pollen, nectar, and guttation fluids, and the foods grown by those plants ( Jeschke et al Neonicotinoids with negatively charged substituents (nitro and cyano groups) interact with a positively charged amino acid residue in insect nAChR that is not present in mammalian nAChR. Beyond their generally favourable toxicity profiles, neonicotinoids are also attractive as insecticides because they are water-soluble and have reasonably long half-lives, allowing for long-term protection.
