Mating time, behavioural activity, and sex pheromone production and release of adult Spodoptera litura (F.) were examined under artificial light conditions (16L : 8D). Mating behaviour represented as a typical calling position of female moths showed two peaks of activity during a 24 hr period. The major peak at 23 : 00 was 3 hr after initiation of the dark period and the minor one at 3 : 00 was just 1 hr before the end of the dark period. Response of the male moths to the sex pheromone, which was extracted from the virgin female moths, also showed two peaks coincided in time with those of the female's calling, and the mating period actually coincided with the time of maximal activity of the male response and the female calling. The sex pheromone activity in the virgin female was high at the time of light-off and light-on, representing two peaks during a 24 hr period. On the other hand, release of the sex pheromone from the virgin female gradually increased from initiation of the dark period, and decreased toward the end of the scotophase. This inverse relationship indicates that the change in sex pheromone activity is related with the production and release of the sex pheromone in the virgin female.
