Insect pests and phytophagous mites cause a considerable loss to tropical root crops in the field. Major pests include the sweet potato weevil Cylas puncticollis, cassava mealybug Phenacoccus manihoti, cassava green spider mite Mononychellus tanajoa, yam beetle Heteroligus meles, and taro hornworm Hippotion celerio. Field and laboratory evaluation experiments indicate that entomopathogenic microorganisms may be adequately used in the management of insect and mite pests in root crops. The highest promise probably lies with fungal pathogens (Beauvaria bassiana, Hirsutella thompsonii, Metarhizium anisopliae, Nomuraea rileyi, Entomophthora thaxteriana, and E. parvispora), but bacterial (Bacillus thuringiensis), microsporidian (Nosema locustae) nematode (Steinernema feltiae) and even viral (Baculoviruses) pathogens may be exploited in an integrated pest management programme of tropical root crop pests.
