Abstract:
The legume spotted pod borer, <em>Maruca vitrata</em> is a serious pantropical insect pest of grain legumes. Experiments were conducted at NBAIR, Bangalore. Female calling studies on <em>M. vitrata</em> were investigated at 27±2<sup>áµ’</sup>C with 65-70% of relative humidity and photoperiod of 12L: 12D. Calling behaviour of virgin females of <em>M. vitrata</em> observed from one to eight days. Females started calling from 2<sup>nd</sup> hour of scotophase (7pm) and terminated at 3am (scotophase). The mean percentage of calling was maximum at 6<sup>th</sup> hour of scotophase in 3 day old moths with 44%. None of the females called during first hour of scotophase. The results revealed that age of insects determine the female calling pattern of <em>M. vitrata</em>. These studies provide valuable information for indentation of sex pheromone in insects.
