The reasons an integrated pest and disease control in cassava is justified are analyzed. Some cultural practices are listed that would lessen the problems caused by negative production factors within an ecosystem and would give high stable yields. Recommendations are given to maintain and enrich ...

Cassava mealybugs constitute one of the major production problems of cassava in Africa and the Americas. The species already identified that attack cassava in the Americas include Phenacoccus manihoti, P. herreni, P. gossypii, and P. grenadensis. Since its introduction into Africa, P. manihoti ha...

A program of biological control of the cassava hornworm appears feasible. The following biological control agents have been found to reduce hornworm populations effectively: Trichogramma spp. (egg parasites), Apanteles spp. (larval parasites), Polistes spp. (larval predators) and Bacillus thuring...
Based on the considerations related to the characteristics of cassava, centers of origin, and the traditional system of cultivation, several conclusions were made regarding the relationships between the plant and NPFs, constituted by disease and pest pressures and edaphic and climatic factors. It...

Oligota minuta is one of the major dominant predators of Mononychellus tanajoa, consuming eggs and movil stages of the mite. At the Centro Internacional de Agricultura Tropical, Palmira, Colombia, Oligota adult populations on cassava var. M Col 113 were counted 4 times/day (6 am, 9 am, 1 pm, and ...
