The termiticides often used include arsenicals, metal salts, inorganic acids, organochlorine compounds, organophosphates, carbamates, acylamines, silico alkanes, pyrethroids, heterocyclic compounds, insect growth regulators, natural biorational pesticides, and so on, especially the last three kinds of termicides may be have the greatest prospect.

This paper discusses the characteristics,degradation,persistence and bioavailability of main termiticides such as chlordane,mirex,chlorpyrifos,bifenthrin and imidacloprid according to relative published information to provides a theoretical basis for understanding and predicting the longevity or persistence of these termiticides to control termites.

Environmental behavior of preventive termiticides;
