Three application of six botanical insecticides and one chemical viz; cypermethrin 25 EC (0.006%), Neem oil (4%), NSKE (5%), Pongamia oil (5ml/lit), Iluppai oil (2%), Garlic bulb extract (4%), Tobacco leaf extract (3leaf/lit) were evaluated against shoot and fruit borer, Leucinodes orbonalis. Minimum percent of shoot infestation, percent fruit infestation and B:C ratio were observed in cypermethrin 25 EC with (5.980%, 6.280% and 1:5.25) respectively. Which were followed by Neem oil (6.306%, 6.556% and 1:4.78) < NSKE (6.580%, 7.253% and 1:4.46) < Pongamia oil (7.346%, 7.273%, and 1:3.79) < Iluppai oil (7.656%, 7.793%, and 1:3.68) Garlic bulb extract (8.056%, 8.240% and 1:3.49) < Tobacco leaf extract (8.646%, 8.520% and 1:3.10) <untreated control(water spray) (11.756%,14.923% and 1:2.25) respectively.

The eggplant or aubergine or brinjal (Solanum melongena L.) is in South-East Asian countries including India, Bangladesh, Sri Lanka, China, Japan etc. It is a native of Indo-Burma region, and was known to be grown in India since ancient times. Majority of Indians are vegetarian, with a per capita consumption 135 g per day as against the recommended 300 g per day. It is still very less than recommended diet level (Dhandapani et al. 2003). Brinjal is normally attacked by number of insect pests right from seeding stage till harvest. Among these pests, shoot and fruit borer Leucinodes orbonalis Guenee. (Lepidoptera : pyralidae) is most destructive one infesting the growing shoot just before the flowering stage and continue to infest the fruit after their formation. It is active throughout the year particularly during high temperature and humidity causing great damage to brinjal in South Africa, Congo, Malaysia and India (Butani and Jotwani 1984). It is the important limiting factor for successful cultivation of brinjal crop as this pest alone can cause a loss up to 70 per cent in yield.
