Damage caused by the fruit fly Bactrocera dorsalis (Hendel) (syn. B. invadens Drew, Tsuruta & White) (Diptera: Tephritidae) on mangoes in Senegal leads to production losses. A potential biological control agent against this pest is the weaver ant Oecophylla longinoda Latreille (Hymenoptera: Formi...

Introduction. African fruit production, as well as regional and international fruit trade,have experienced heavy economic losses over the past decade due to the damage caused by fruitflies, especially B. invadens Drew Tsuruta & White (Tephritidae: Diptera). Bactrocera invadensattacks fruits belon...

Although numerous adults of the buprestid genus Steraspis Dejean, 1833, have been captured in West Africa, little is known about the biology of the known species, especially about their immature stages. The objective of the present field observations was to increase the knowledge on the biology o...

Mango (Mangifera indica L., Anacardiaceae) is a popular fruit in Africabecause of its high nutritional and economic value. However, smallholders in Benin, aWest African country, are currently unable to take advantage of this potential becauseof various constraints along the value chain. A survey ...

Au Mali, la production annuelle de mangues est estimée à 100 000 t. Du fait de problèmes structurels et phytosanitaires principalement liés à l'action des mouches des fruits, rarement plus de 1 % de cette production est exporté. L'objectif principal de cette étude a été de mettre au point une lut...
