INCIDENCE AND ABUNDANCE OF BRINJAL SHOOT AND FRUIT BORER LEUCINODES ORBONALIS GUENEE

Abstract

Based on the experiments conducted at Vegetable Research Station, Kalyanpur, Kanpur under Chandra
Shekhar Azad University of Agriculture and Technology, U.P, the infestation and intensity of Leucinodes
orbonalis Guenee on young plants were recorded by counting infected and healthy shoots on randomly
selected ten plants. The results of two consecutive years revealed that the adults population of brinjal shoot and
fruit borer Leucinodes orbonalis Guenee fluctuated to a great deal not only from year to year but also in
different months. Adult increased considerably in the month of October and November and decreased in
subsequent weeks of December. The maximum temperature and abundance of moth showed a positive
correlation (r = 0.319) during both the years. The correlation coefficient of minimum temperature and moth
trapping also came out was positive (r = 0.3893) indicating the minimum temperature plays an important role
in building up of moth population.
