Integrated pest management strategies for sustained control of grasshoppers and locusts in Mali

During the Winter and Spring of 1988, field trials were conducted along Sudan's Red Sea coast of the environmental impacts of six pesticides used to combat desert locusts: bendiocarb, carbaryl, chlorpyrifos, fenitrothion, lambda-cyhalothrin, and malathion. No dramatic environmental impacts resulted. Each pesticide did significantly reduce populations in at least two of the five orders of non-target arthropods (spiders, true bugs, beetles, flies, and bees and wasps), but arthropod numbers rebounded rapidly. Some of the pesticides were less harmful than others to specific arthropod groups. Carcass searches revealed no dead or injured veterbrate wildlife, and normal behavior was observed among more than 5,000 live birds counted during 160 transect runs. No phytotoxicity was observed, and all the pesticides degraded rapidly in the environment. However, the use of chlorpyrifos and fenithrothion may require restrictions on post-spray harvesting, and bendiocarb applications should be limited to areas not used for agriculture or grazing. The major conclusion is that single applications of all six pesticides, except possibly bendiocarb, can be performed safely in grassland areas infe
