Abstract
The females of the black cutworm, Agrotis ipsilon ( Hufn), produce their sex pheromone early at the beginning of their emergence. Males also can percept this pheromone at the same age. After emergence, the pheromone production and perception increase rapidly, through the first day and continue till the 5th day after emergence. The pheromone production and perception increases to reach its maximum on the second day and continues at a high titer except during the last few days of female life. As the black cutworm has a short life span, it could be concluded that the sex pheromone production by females and perception by males continues at a high level during most of their life. Pheromone production and perception by the black cutworm moth was considerably affected by gamma irradiation applied during the full grown male and female pupae with 50, 100 and 150 Gy. Pheromone production in female decreased with increasing doses more than pheromone perception in P1 male.
