Book Chapter 1981

Autor: International Center for Tropical Agriculture

Losses in root and planting material production caused by different pests as well as their biological control are evaluated. Studies of pests damaging dried cassava in storage were initiated. Biological aspects and form of attack of the following pests are described: stemborers (Lagochirus rogers...

Typhlodromallus aripo, a predatory phytoseiid species of the cassava green mite Mononychellus tanajoa was introduced to the Democratic Republic of Congo in 1998. It established easily and spread quickly to other areas from the sites of first release. But its dispersal was constrained by intense c...

Little is known about the inheritance of agronomic traits in cassava (Manihot esculenta Crantz). The vegetative multiplication of cassava allows cloning of individual genotypes, and separates environmental from genetic variation in the within-family variation. Knowing the magnitude of between- an...
