Fruit flies are pests of great economic importance due to their quarantine pest status and losses recorded in West Africa. An inventory of parasitoids associated with fruit flies in mangoes, guavas, cashew, pepper and major wild fruit crops was carried out in northern-central Benin in 2005, 2006,...

Oecophylla ants are appreciated for their control of pests in plantation crops. However, the ants ? nest building may have negative impacts on trees. In this study we tested the effect of ant densities and nest building on the leaf performance of mango trees. Trees were divided into three gro...

Damping-off and stem rot disease-causing Sclerotium rolfsii has been reported as a destructive soil-borne pathogen of numerous crops, especially in the tropics and subtropics. Trials were conducted to test the efficacy of biocontrol agents alone or combined with Moringa oleifera leaf extracts for...

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...

Damping-off and stem rot of cowpea is an important soil-borne disease worldwide. Cowpea fields were randomly chosen in each agro-ecological zone in Benin and surveyed in 2001 and 2002 to determine the occurrence of the diseases throughout the country. Diseased plants, prevailing environmental con...

Prey capture and food scavenging activities of Oecophylla longinoda were monitored through regular weekly samplings during two consecutive years (2009–2010) in a large mango orchard of the Borgou Department of Benin, West Africa, a main mango production area located in the Sudan agro-ecological z...

The tritrophic interactions between mangoes (Mangifera indica), two frugivorous fly species of greateconomic significance, Bactrocera invadens and Ceratitis cosyra, and weaver ants (Oecophylla longinoda)were studied in Benin. We investigated whether Oecophylla cues affect B. invadens and C. cosyr...

Fruit flies are pests of economic importance inWest Africa due to their quarantine status and losses recorded in fruits and vegetables. Before the introduction of exotic species of parasitoids against any exotic fruit fly species, it is fundamental to first determine the presence and monitor the ...
