Cotton IPM is only at step one now. The success of the boll weevil eradication program, the widespread use of Bt cotton, the development of insecticides that are less toxic to beneficial insects and integrated pest management are the major factors contributing to a greater reliance on beneficial insects and a diminished use on pesticides. Entomologists are also concerned that regulatory pressure may cause the loss of many organophosphate insecticides upon which farmers now depend. Integrated pest management, including use of beneficial insects, may help extend the life of these pesticides. Predators attack and feed on multiple prey while parasites live in or on their hosts during immature development.
Pathogens are organisms that cause disease, primarily fungi and viruses.
