Abstract

Since 1970, Heliothis armigera has shown resistance to both DDT and Toxaphene, but not to the organophosphates, which include Parathion. DDT, the cheapest and most effective chemical available, gave control of Heliothis until the development of resistance in 1970- 71.

Trials then showed that a mixture of DDT and Toxaphene was more effective than DDT alone.
