Abstract
The present investigation entitled “Biology and management of Brinjal shoot and fruit borer (Leucinodes orbonalis G.) in low hill of Himachal Pradesh” were carried out at college of Horticulture and Forestry, Neri, Hamirpur. The study was conducted to record data on biology and management of brinjal shoot and fruit borer. From the study, it was concluded that incubation period of Brinjal shoot and fruit borer ranged from 3 to 5 days. The pest passed through five instars ranging from 15 to 18 days, pupal duration of 8 to 10 days, adult longevity of male and female moth varied from 1 to 3 days and 3 to 5 days, respectively. The fecundity of adult female ranged from 160 to 240 eggs. Adult male moth was shorter than adult female moth in length and also in wing span. During the pre-treatment, number of infested shoots ranged from 63.03 to 67.55 per cent and number of infested fruits ranged from 65.03 to 68.74 per cent in different plots. The incidence of shoot and fruit borer was significantly reduced by all insecticidal/ biopesticidal treatments. Among different management practices chlorantraniliprole @ 0.01% was found most effective to control shoot and fruit infestation of brinjal shoot and fruit borer, followed by cyantraniliprole @ 0.02%.
