In cotton production, there are many factors that can reduce crop yield. One important cause is arthropod insects. Insects that cause loss to the fruit are frequently more destructive than those that damage leaves, stems, and roots. Cotton in Zimbabwe is subjected to yield and quality loss due to various lepidopterous pests. The African bollworm (Helicoverpa armigera), red bollworm (Diparopsis castanea), spiny bollworms (Erias insulana and E. biplaga) and pink bollworm (Pectinophora gossypiella) causes the greatest yield loss annually. This review describes integration of pest control tactics directed against the bollworm pest complex which put together the most effective mixture of tactics, allowing control of pests while keeping in mind the productivity of the fields, the role of beneficial organisms and safety considerations.
