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

Field experiments were conducted to evaluate the efficacy of different biopesticides, viz., Nomuraea rileyi @ 1 × 108 conidia/lit, Beauveria bassiana @ 1 × 109 CFU/ml minimum @ 5 ml/lit, Metarhizium anisopliae @ 1 × 109 CFU/ml minimum @ 5 ml/lit, dipel @ 1 kg/ha, spinosad 45 SC @ 0.5 ml/lit, neem seed kernel extract (NSKE) @ 5% and neem oil @ 2% against foliage feeders of soybean namely, semi looper (Chrysodeixis acuta) and tobacco caterpillar (Spodoptera litura) during Kharif, 2016. The result revealed that all treatments were significantly superior over control. The mean larval population of C. acuta and S. litura ranged from 1.29 to 9.37 and 0.92 to 6.98 larvae per meter row length (mrl) at 3, 7 and 10 days respectively after the application of treatments. The treatments comprising Spinosad 45 SC @ 0.5 ml/lit proved highly effective in reducing the population of C. acuta and S. litura with lowest overall mean larval population of 4.71 and 3.02 larvae per mrl, respectively. Against C. acuta NSKE @ 5% was least effective and against S. litura neem oil was observed as least effective with maximum over all mean larval populations of 7.75 and 4.97, respectively.Keywords
