Journal Article 1994

Autor: Neuenschwander, P.

During the Africa-wide Biological Control project, the neotropical parasitoid Epidinocarsis lopezi (De Santis) (Hymenoptera: Encyrtidae) was established in 26 African countries, causing a satisfactory reduction in the population density of the cassava mealybug Phenacoccus manihoti Mat.-Ferr. (Hom...

The spiralling whitefly, Aleurodicus dispersus Russell (Hom., Aleyrodidae), a native of Central America, was found in continental Africa for the first time early in 1992, and has since spread to five West and Central African countries. It is a polyphagous pest which causes substantial damage also...

1. A unified ratio-dependent supply-demand driven tritrophic model of the cassava (Manihot esculenta Crantz) system was compared to field data, and then used to explore the basis for the successful control of cassava mealybug (CM, Phenacoccus manihoti Mat.-Ferr.) in Africa by the exotic parasitoi...

Autor: Neuenschwander, P.

Among several natural enemies introduced to combat the cassava mealybug, Phenacoccus manihoti (Homoptera: Pseudococcidae), the neotropical parasitoid Apoanagyrus (Epidinocarsis) lopezi (Hymenoptera: Encyrtidae) was the most successful. It established in 26 African countries, causing a satisfactor...

Autor: Cudjoe, A. Neuenschwander, P. Copland, M.

In surveys of cassava fields in the coastal savanna and rain forest zones of Ghana, eight species of ants, mostly in the genera Camponotus, Crematogaster and Pheidole (Hymenoptera: Formicidae), were found attending cassava mealybug, Phenacoccus manihoti Matile-Ferrero. Ant densities were much hig...
