The male moth catches in traps commenced from the 4th week of November, 2015 and continued upto 2nd week of April, 2016. In the traps where septa were replaced at 15 days intervals, the population attained peak during the 11th standard week registering 49.4 moths/trap/week. More or less same order of moth catches was observed in another traps in which septa were changed after every 30 days interval but, quantum of moth catches was slightly lower. The maximum temperature (r = 0.581 and r = 0.546), minimum temperature (r = 0.555 and r = 0.525), total rainfall (r = 0.592 and r = 0.606) and sunshine hours (r = 0.551 and r = 0.531) resulted positive significant where septa were replaced after 15 and 30 days interval, respectively.
