classes of insecticides. Our studies on the nicotinic receptor structure in the neonicotinoid-bound state revealed a unique niche of about 6 A depth beyond the nitro oxygen or cyano nitrogen tip. The N-substituted imino pharmacophore was therefore extended to fill the gap. Excellent target site selectivity with high insecticidal activity and low toxicity to mammals were achieved rivaling those of the
