Type-3. Among the various treatments like imidacloprid 17.8 SL @ 1.0 ml/lit., indoxacarb 14.5 SC @1.0 ml/lit., profenofos 50 EC @ 2.0 ml/lit., spinosad 45 SC @ 0.4 ml/lit., thiamethoxam 25 WG @ 0.1 gm/lit., acephate 75 SP @ 0.7 gm/lit. and untreated control, among them imidacloprid 17.8 SL was found most effective in reducing the mean shoot infestation and fruit infestation followed by indoxacarb 14.5 SC, profenofos 50 EC, spinosad 45 SC, thiamethoxam 25% WG and acephate 75 SP.

In Indian agriculture, vegetable farming occupies an important place because of their nutritional, medicinal and economical values. The area under brinjal cultivation was estimated to be 711.3 (‘000’ha) with total production of about 13557.8 (000 mt) with the productivity of 19.1 (mt/ha) during 2013-14. The crop occupied 7.6 per cent of the whole vegetable area with production up to 8.3 per cent of entire vegetable grown in country [1]. The egg plant or brinjal (Solanum melongena L.) is a plant of family solanaceae. It is a native of India -Burma region, and was known to be grown in India since ancient time. Brinjal is susceptible to adverse environmental conditions like severe frost as well as long and warm growing season. A mean temperature of 20-30°C is most favorable for its successful production in northern plains. Like any other crops, brinjal is also attacked by a number of insect pests at various stages of its growth, which act as a limiting factor in the profitable cultivation of this crop. The crop is attacked by about 140 species of insect and non-insect pests belonging to 50 families [8, 11] listed 53 insects, whereas [7] listed 36 insects attacking on brinjal. Out of which numerous insect pests viz., shoot and fruit borer, leaf hopper (Amrasca biguttvla bigultula), aphid (Aphis gossypii), hadda bettle (Epilachnaspp.) and brinjal stem borer (Euzophera particella) have been reported as important pests of brinjal [4, 6]. Among these, shoot and fruit borer L. orbonalis (Lepidoptera: Pyralidae) is most destructive and the major limiting factor in quantitative as well as qualitative harvest of brinjal fruits. This pest is widely distributed in Malaysia, Mayanmar, Sri Lanka, India, Pakistan, Germany and East Africa [1]. L. orbonalis causes damage in brinjal crop, both at vegetative as well as reproductive stage. The young larvae of this pests bore into petioles, midribs of large leaves and tender shoots, resulting in dropping. Later they bore into fruits .Crop losses by L. orbonalis have been reported to an extant of 20.70 to 88.70 per cent in various parts of India. Losses caused by this pest are as high as 20.7 per cent in Delhi [15], 70 per cent in West Bengal [3] and 13.28 to 88.89 per cent in Haryana [9, 12]
