The study of the parasitic community of Bactrocera dorsalis revealed that Diachasmimorpha tryoni was the species most capable of controlling populations of this fly. In this perspective, the study of the biology of this parasitoid was carried out under orchards semi natural Conditions in southern, central, northern areas of Côte d’Ivoire. The study parameters D. tryoni, highlighted in the north, the number of eggs (113.33 ± 2.62) was higher while the development time and the life was short. South, longevity was higher (36.03 ± 1.47 days) and longest development time (18.33 ± 1.16 days). In the center, the parameter values were between those obtained in the north and south. In the three agro-ecological zones, the male development time was shorter than that of the female. The resulting sexual rates were in favor of males. Changes in climatic conditions seem to affect the reproductive ability of D. tryoni.
