Journal Article 2009

Autor: Hailemichael, Y. Schulthess, F. Smith, Jimmy W. Overholt, W.A.

Three gregarious, endoparasitic braconids, a Kenyan strain of Cotesia sesamiae, and the exotic Cotesia flavipes and Cotesia chilonis were imported into Benin as candidates for biological control of stem- and cob borers of maize and stemborers of millet. Host acceptability and host suitability of ...

Journal Article 1997

Autor: Hailemichael, Y. Schulthess, F. Smith, W. Overholt, W.A.

The palaeotropical, gregarious, endoparasitic braconids Cotesia sesamiae, Cotesia flavipes and Cotesia chilonis were recently imported into Benin as candidates for biological control of stem and cob borers of maize. Host acceptability and host suitability of six gramineous borers occurring in wes...

Journal Article 1986-10

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...
