We studied the dispersion patterns of the exotic endoparasitoid, Diachasmimorpha longicaudata (Ahsmed) (Hymenoptera: Braconidae), in 1999 (summer) and in 2000 (winter) in a citrus orchard in southeast Brazil. DifIerent population densities of D. longicaudata were released in the centre of the orchard, and their dispersion was determined by using yellow, sticky, rectangular traps, placed in various distances and heights around the release point. Our results suggest that during summer, climatic conditions did not afIect dispersion. However, in winter, dispersion rates were positively afIected by temperature, and negatively by rainfall. Both estimated dispersal distance and surface were higher in summer than in winter for ali release densities. Dispersion peaked at 2000 parasitoids ha - 1 in summer and 8000 parasitoids ha - 1 in winter. The importance of our results for the biological control of fruit flies by augmented or innoculative releases of D. longicaudata in southeast Brazil is discussed. |
