Abstract: Brinjal crop is regularly and simultaneously attacked by several insect pests like leafhopper (Amrasca bigutulla bigutulla Ishida), whitefly (Bemisia tabaci Gennadius) and brinjal shoot and fruit borer, Leucinodes orbonalis Guenee. The yield lossescaused are as high as 70-92% in India and the pest is reported to cause 3.3-68.9% damage to flowers and 47.6-85.8% damage to fruits in Orissa. The management of this pest is through calendar spraying of conventional insecticides irrespective of pest incidence. Insecticides suchas bio-pesticides, botanicals and chitin synthesis inhibitors, have been evaluated against L. orbonalis in the past and are being used. The bio-efficacy of thiodicarb (0.28125, 0.46875 and 0.75 kg a.i./ha) and other insecticides, i.e. Cartap hydrochloride [cartap] (0.5 kg a.i./ha), diflubenzuron (0.1 kg a.i/ha), carbofuran (1.0 kg a.i./ha) and Triazophos (0.5 kg a.i./ha) and Fipronil (0.1 kg a.i./ha), against brinjal shoot and fruit borer, Leucinodes orbonalis. The results revealed the superiority of thiodicarb at its highest dose of 0.75 kg a.i/ha as it recorded the lowest shoot (1.41%) and fruit damage (20.86%). This compound at its highest dose also recorded the highest aubergine fruit yield of 148.45 q/ha. The efficacy of some new groups of insecticides against the shoot and fruit borer (Leucinodes orbonalis) and beetles (Epilachna spp.) infesting aubergine cv. Utkal Madhuri,), application of fipronil+ triazophos + cartap hydrochloride recorded the lowest shoot borer (% shoot infestation) and beetle damage (% leaf infestation) of 11.89 and 3.05%, respectively.
