Adult emergence period, the calling behavior pattern and the mating ability of female depending on ages, 9day old male's response to sex pheromone released from each 1- to 5-day old female, and the structure and location of sex pheromone gland were obse~edin Ostrinia furnacalis. Adults usually emerged from 1 hour before to 1-2 hours after the beg~nning of scatophase under the 16L/8D photoperiod. And most active calling behavior was obserued for two hours from the 5th to 7th hours of scotophase among 2- and 3-day old females, and 3-day old male' response to 3-day old females was higher than to any other age of females during the 5th-8th hours of scotophase. Mating frequency was higher at the 4th-7th hours after the beginning of scotophase. Among 1. to Cday old females extruding sex pheromone gland, more than 65% of them successfully mated with 2- to 4-day old males. And, 2- or 3-day old females exhuding sex pheromone gland showed an abdiw. over 60%, to mate with each 1--5-day old males. Hypertrophied cell layers, presumed to be a sex pheromone gland of female adults, were located at two intersegmental membranes between the 8th & 9th, and the 9th & 10th abdominal segments.
