Abstract
This paper details the results of the effect of releases of the egg parasitoid Trichogramma chilonis Ishii in minimising populations of the sugarcane stalk borer (Chilo auricilius) and thereby increasing the yield of sugarcane. The experiment was conducted in two successive years, 1999-2000 and 2000-2001, and 10 releases of the parasitoids were made in treated plots in each year. No releases or other controls occurred in the control plots. The infestation index of stalk borer was significantly higher in control plots than in treated plots in both years, 4.45% and 1.562% in control plots and 1.02% and 0.578% in treated plots during the years 1999-2000 and 2000-2001, respectively. Due to the reduction in the infestation index, the yields of treated plots were significantly higher by 24.6 t/ha and 20.6 t/ha than control plots during 1999-2000 and 2000-2001, respectively.
