Abstract
Chalcid Wasps associated with Ficus sycomorus L. have never been subject of a study in Senegal despite their importance. Several species of Hymenoptera interact inside the figs of F. sycomorus whose Ceratosolen arabicus Mayr assures its pollination. This study, led in three climatic domains in Senegal, permited to identify eight species of Chalcid Wasps; we also noticed that fragmentation of the environment of F. sycomorus does not strongly influences the distribution of C. arabicus. However, it seems that the negative impact of Sycophaga sycomori (L.), but especially of Apocrypta longitarsus Mayr on the pollinator of F. sycomorus in Senegal, may be worrying.
