The effective dispersal distance from the point of release of Trichogramma chilonis Ishii under sugarcane ecosystem was studied based on the recovery made by exposing Corcyra eggs at different distances and directions. The mean per cent recovery made at one to five metre distance did not differ significantly. Beyond five metre, the per cent recovery reduced at increasing rate. Fifty to sixty per cent more recovery was found at downwind sector than at upwind sector at 60 days after planting. At 90 days after planting the recovery made at different directions were non-significant.
