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 5th and 2nd week of December during 1st and 2nd year respectively. The brinjal shoot and fruit borer incidence showed positive correlation with maximum relative humidity, rainfall and wind speed during 1st year and with maximum relative humidity and sunshine hours in 2nd year. The damaged fruit and fruit weight loss varied from 3.76 to 45.45 percent and 3.00 to 67.71 percent in 1st year and 5.71 to 44.26 percent and 3.00 to 51.33 percent in 2nd 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%).
