Synthetic pyrethroid insecticides are being used with greater frequency in the United States to replace residential and some agricultural organophosphorus (OP) and carbamate insecticides.

In a monitoring study residue levels of organochlorines (OC), synthetic pyrethroids (SP), organophosphates (OP) and carbamates were determined in unprocessed and processed three vegetables viz. brinjal, cauliflower and okra to know the residue levels and evaluate the effect of different household processes (washing and boiling/cooking) on reduction of residues.
The relative toxicity of emulsions of various pyrethroids was evaluated against the third instar larvae of Pieris brassicae in the laboratory.
