Seasonal incidence and management of brinjal shoot and fruit borer, Leucinodes orbonalis

In two year study, maximum population of brinjal shoot and fruit borer, Leucinodes orbonalis in Allahabad, U.P. was observed in 5^th and 2^nd week of December during 1^st and 2^nd year respectively. The brinjal shoot and fruit borer incidence showed positive correlation with maximum relative humidity, rainfall and wind speed during 1^st year and with maximum relative humidity and sunshine hours in 2^nd year. The damaged fruit and fruit weight loss varied from 3.76 to 45.45 percent and 3.00 to 67.71 percent in 1^st year and 5.71 to 44.26 percent and 3.00 to 51.33 percent in 2^nd year. One larval parasitoid of brinjal shoot and fruit borer, Eriborus argentiopilosus (Hymenoptera: Ichneumonidae) was identified. The extent of parasitization ranged from 2.01 to 24.61 percent. Most effective treatment was application of Chlorpyriphos followed by NSKE (5%) and Nerium (10%).
