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...
Part of the methodology of the analysis applied to the project of the hornworm (Erinnyis ello) on cassava is presented. The project studies the hornworm life cycle and population dynamics and the economic impact on cassava production under 2 conditions (1) in cages with controlled ideal condition...

For the biological control of Ernnyis ello, an application of Bacillus thuringiensis (400-500 g/ha for aerial applications or 2-3 g/l of water for land applications), together with a surfactant with adherent properties, is recommended. When a hornworm population increase is foreseen due to the in...

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 ...

Weeds by definition are plants that grow in the wrong place. When their seeds or other plant parts are transported to other regions
where their natural enemies are absent, they can multiply unhindered. Indigenous plants, especially those that are adapted for
invading disturbed areas, can also bec...
