Abstract:
Brinjal (Eggplant) Solanum melongena Linnaeus is the most important vegetable of hot and humid climates. A wide range of essential biochemicals and minerals belongs to brinjal. It is a fairly good source of iron, calcium, phosphorous, potassium and vitamin B group. Brinjal Shoot and Fruit Borer Leucinodes orbonalis Guenee is the major infectious insect causing a great damage to plants. BSFB generally depends on brinjal but it may infest other solanaceous field crops and may be on wild hosts. The insect has been reported a number of crops such as S. tuberosum (potato), S. lycopersicum and some other Solanaceous crops. The damage by this borer starts at seedling stage and continues till the last harvest of fruits. Egg-laying occurs during night and incubation period ranges from 3-8 days depending of environmental conditions. Larval period completes in 12-22 days depending upon environmental situations and passes through five instars. Full grown larvae pupate into the soil or under plant debris and dropped dead shoots. Adult of BSFB is a whitish moth which hides during day time and activates from dusk to perform various activities like mating oviposition. Larvae bore into fruits and shoots and in younger plants, caterpillars drill into midrib of large leaves. At the time of maturity, damage of the insect on fruits causes a serious loss in yield.
