There are no worldwide statistics on the total number of insects and mites that were resistant to insecticides in 1940. But it can be assumed that insecticide resistance was at its lowest in 1940 since that date launches the decade that eliminated many an arachnid and an insect through DDT and since the immunity is evolutionary, with resistance to DDT being detectable in house-flies by 1947. Insecticide resistance spurs laboratory experiments with and refinements in conventional insecticides and genetically modified crops since, as an example, Hessian flies (Mayetiola destructor) inspire successive breedings of eight major resistant genes into wheat because of the insect pest's corresponding protective adaptations and resulting immunity.
