Establishment and dispersal of Cotesia flavipes (Cameron) (Hymenoptera: Brachonidae), an exotic endoparasitoid of Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae) in northern Tanzania
African Entomology 5 (1), 71-75
Abstract: Cotesia flavipes, an Asian endoparasitoid of cereal stem borers, was recovered in the Tarime and Magu Districts in northern Tanzania in 1995. No recoveries of the parasitoid were made from other areas of Tanzania during the survey, including the Ukiriguru and Kilosa areas, where the parasitoid had been released in 1970. It was consequently concluded that the parasitoid spread into Tanzania from a founding population that may have inadvertently been released from the Mbita Point Field Station of ICIPE in 1991. The southernmost point from which C. flavipes, was recovered was 240 km from Mbita Point, the dispersal rate of the parasitoid was estimated to be 60 km per year.
