The diamondback moth, Plutella xylostella (L.) is the major insect pest of cabbage crops in Togo and Benin. For control, farmers very often resort to spraying chemical insecticides at high dosages with frequent applications. Bioassays were carried out on three populations of P. xylostella, two fr...

Distribution and prevalence of nematodes (Scutellonema bradys and Meloidogyne spp.) on marketed yam (Dioscorea spp.) in West Africa
Nine Nigerian populations of Scutellonema bradys, obtained from infected yam (Dioscorea spp.), were assessed following inoculation onto susceptible yam (Dioscorea rotundata) cv. TDr131 in pot and field experiments in Nigeria between 2002 and 2004. In addition, geographically separated populations...

Trypanosomiasis, a disease transmitted by the tsetse fly, is a major constraint to livestock production and mixed farming in Africa. This study examines the economics of the village production of trypanotolerant cattle recently introduced in an affected area of Togo that was previously virtually ...

The economics of recently introduced village cattle production in a tsetse affected area. (II): Trypanotolerant cattle in southern Togo
A study was made between 1979 and 1983 on physical, productivity and reproduction characteristics of 193 Baoulé cattle at Avétonou Research and Breeding Station. Height at withers and loin, body length, length of head, chest girth, width of head and loin were measured at 1, 3, 6, 12, 18, 24, 30, ...
Background: To optimize the success of insecticide-based malaria control intervention, knowledge of the distribution of Anopheles gambiae species and insecticide resistance mechanisms is necessary. This paper reported an updated data on pyrethroids/DDT resistance in the An. gambiae s.l population...
