Abstract
The mating behavior of the maize weevil, Sitophilus zeamais, was examined under laboratory conditions, and an ethogram was constructed. Using transition probabilities between two successive acts, copulatory sequence was analyzed. Copulation lasted an average of 4.8 h and was characterized by abdominal flexing by the males. Within 3.8 min of dismounting, on average, the male completely extruded his aedeagus. Mating did not occur before the age of 3 d. Virgin females began copulation sooner and were more likely to mate than previously mated females. Experienced males were more successful than virgins. Copulation duration was not affected by the age or mating status of the female, nor by the period of time since the first copulation.
