Although the precise genetic and ecological factors differ among pests that have become resistant, in all cases resistance is driven by one process -- selection. Pest species evolve pesticide resistance via natural selection: the most resistant specimens survive and pass on their acquired heritable changes traits to their offspring. Tell us about the effects of pesticides on the environment. For example, PIP crops such as corn and cotton have genes for the production of Bacillus thuringiensis (Bt) endotoxin (derived from the bacterium Bacillus thuringiensis). omg guys i got a new insta it is taysha_bby so go follow me BYE oh and tiktok so go follow me on there it is glittetay12 OMG YAY!. c. organophosphates b. constantly decreasing doses of pesticides are needed to control pests.
