ResumoSolanum melongena, Eggplant (Brinjal), is one of the most economically important vegetable crops in South Asia, South East Asia including Nepal, India, Pakistan, Srilanka, Bangladesh, Thailand, Philippines, Cambodia, and Laos.It holds ample significance as a vegetable crop in Terai and Mid-hill of Nepal since it can be grown in variety of soil and can be cultivated throughout the year.Generally, it is grown in Terai and Mid-Hill region during Bhadra-Asoj (August-September) and Magh-Falgun (February-March) respectively.Brinjal is a Kharif season crop in Nepal and mostly thrives best during long summer season with optimum temperature of 20°C-30°C for growth and fruit development.In Nepal, Brinjal cultivation is still non-commercial in most parts of the nation and further research on its pests and pathogens are yet to be carried out.Several insects like Fruit and Shoot Borer, White fly, Leaf hopper, Thrips, Mites, Leaf Roller, Red Spider Mite etc. are found to cause loss in Brinjal in different parts of the world.The key pest of Brinjal; Brinjal Fruit and Shoot Borer (Leucinodes orbonalis) are responsible for causing huge damage to the growth and development of stems, young sprouts, buds and fruits as well.This insect can also attack other vegetables of solanaceae family (alternate host) and results in severe losses.Larvae bore inside the fruit and reduce its yield up to 70% -75% [1][2][3].This larva of this insect has unique nature of feeding on monophagous diet aided by homing and tunneling behavior which ultimately enables the adult
