Abstract:

The shoot and fruit borer, Leucinodes orbonalis has a countrywide distribution and has been categorized as the most destructive and most serious pest causing huge losses in brinjal. In the present investigation, six species of Trichogramma were used for selection of most suitable species against shoot and fruit borer, L. orbonalis, the per cent parasitism ranged between 3.60 to 93.20 per cent and the highest per cent parasitism was observed in T. evanescens (93.20 %), which was on par with T. chilonis 92.00 per cent. In a dosages experiment, the highest per cent parasitism of 74.1 per cent was recorded in the dosage having 15 adults/sq. m (150000 adults/ha) and lowest parasitism of 44.2 per cent was recorded in dosages of 5 adults/sq. m (50000 adults/ha). Among the two species highest parasitism was recorded in the T. chilonis (68.0 %) compared to T. evanescens (55.9 %) and 100,000 was found to be optimum dosages.
