The relative efficacy of Trichogramma chilonis (Ishii) was evaluated for management of the brinjal shoot and fruit borer in the field condition at the Horticulture Farm of Rajasthan College of Agriculture, MPUAT, Udaipur from July 2016 to February 2017. The result showed that when three dosages of egg parasitoid, T. chilonis applied with 6 and 8 times releases @ 50000, 100,000 and 150,000 parasitized eggs at 10 days interval starting from 15 days after transplanting, releases of 150,000 for 6 and 8 times was found to be most effective with mean shoot damage of 11.96 and 12.66 per cent, respectively, while, the least effective rate was when parasitoid was released @ 50000/ha (T2 and T1) with mean shoot damage of 17.78 and 18.12 per cent, respectively, against fruit borer damage. Six and eight times release of T. chilonis @ 150,000 was most effective with mean fruit damage of 11.67 and 9.80 per cent on number basis, and 11.59 and 9.90 per cent per cent fruit damage on weight basis. The results revealed that the maximum parasitism was recorded for treatments of 8 and 6 times @ 150,000 /ha (47.61 per cent to 47.05 per cent).Keywords
