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...

Aspecies in the Bactrocera dorsalis (Hendel) complex was detected in Kenya during2003 and classified as Bactrocera invadens Drew, Tsuruta&White.Having spread rapidlythroughout Africa, it threatens agriculture due to crop damage and loss of marketaccess. In a recent revision of the B. dorsalis com...

We interviewed half of the mango-growers in northern Benin, including 15 farmers involved in a regional fruit fly project, and held focus group discussions with women fruit-pickers. They were asked about pest management and their knowledge of a weaver ant, Oecophylla longinoda. All considered low...

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...

Parasitoids that oviposit in a concealed host inside a plant part need to be able to find both the plant and the host. Egg parasitoids of fruit-infesting Tephritidae need to assess the oviposition site based both on the host egg and the infested fruit. Infestation by Tephritidae fruit flies threa...

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...
