Autor: Msikita, W. Yaninek, John S. Ahounou, M. Baimey, H. Fagbemissi, R.

During part of the dry season in 1996 (November to December), surveys were made for incidence of root and stem rot in 99 fields of cassava (Manihot esculenta Crantz) randomly selected between latitudes 6°36′N and 7°49′N in Benin (79 fields) and Nigeria (20 fields). Root rot was observed in 65 fie...

Prevalence and severity of Nattrassia mangiferae root and stem pathogen of cassava in Benin

Autor: Msikita, W. Bissang, B. James, B. Baimey, H. Wilkinson, H. Ahounou, M. Fagbemissi, R.

Root rot pathogens were found through diagnostic surveys in all departments (regions) of Bénin, West Africa, to affect 86 to 100% and 96 to 100% of cassava fields during the dry and rainy seasons, respectively. Disease incidence in individual fields ranged between 0 and 53%, and averaged 16 to 27...

Host stage selection and sex allocation by Gyranusoidea tebygi (Hymenoptera: Encyrtidea), a parasitoid of the mango mealbug, Rastrococcus invadens (Homoptera: Pseudococcidae)

Autor: Boavida, C. Ahounou, M. Vos, M. Neuenschwander, P. Alphen, J.J.M. van

Host stage selection and sex allocation by Gyranusoidea tebygi Noyes (Hym,, Encyrtidae) were studied in choice and no-choice experiments in the laboratory. The parasitoid reproduced on first, second, and third instars of the mango mealybug, Rastrococcus invadens Williams (Hem., Pseudococcidae), a...

First report of Fusarium moniliforme causing cassava root and stem rot

Autor: Msikita, W. Yaninek, John S. Ahounou, M. Fagbemissi, R.

Fifty-five samples of diseased cassava (Manihot esculenta) crowns and shoots and discoloured chips were collected from Benin and Cameroon, Africa. Pieces of infected tissue were cultured on agar and incubated for a week. Over 36% of fungal isolates were Fusarium spp. Of the Fusarium isolates, 55%...
