Exchanging natural enemies species of lepidopterous cereal stemborers between African regions

Autor: Schulthess, F. Bosque Pérez, N.A. Chabi-Olaye, A. Gounou, S. Ndemah, R. Goergen, Georg E.

Difficulties of identification of natural enemies of cereal stemborers for 'redistribution' in Africa are discussed. Tritrophic level studies on wild and cultivated habitats of borers and beneficial species are needed to judge the impact of a natural enemy species in the cropping system. Areas wi...

Experimental evaluation of the efficiency of Epidinocarsis lopezi, a parasitoid introduced into Africa against the cassava mealybug Phenacoccus manihoti

Autor: Neuenschwander, P. Schulthess, F. Madojemu, E.

The capability of Epidinocarsis lopezi (De Santis) (Hymenoptera: Encyrtidae) to control the cassava mealybug (CM) Phenacoccus manihoti Mat.-Ferr. (Homoptera: Pseudococcidae) was investigated in Nigeria using physical and chemical exclusion experiments. In two sleeve cage experiments CM population...
