Abstract:
The pest poses a serious problem because of its higher productive potential, rapid turnover of generations and intensive cultivation of brinjal both in wet and dry seasons of the year. It is reported to be attacked by about 140 species of insect pests, of which the shoot and fruit borer (Leucinodes orbonalis Guen.) is the most important one. The 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. Many scientist observed that seasonal incidence of shoot and fruit borer, Leucinodes orbonalis Guen. (on shoot) was more prevalent during vegetative phase of the crop up to the 3rd week of September. The role of temperature, rainfall, relative humidity (Morning) in increasing infestation and intensity on shoot and fruits was very conductive but RH (%) (Evening) responded negatively on borer.
