Interpretive Summary:

Technical Abstract: The maize weevil, the rice weevil and the granary weevil are closely related species in the genus Sitophilus. All are associated with stored grain of all kinds and cause severe damage in post harvest systems worldwide. Sitophinone, the aggregation pheromone of Sitophilus zeamais and S. oryzae, as well as sitophilate of S. granarius have been identified. Behavior studies on S. zeamais and S. oryzae towards natural and synthetic pheromone sources will be reviewed and compared to recent studies on S. granarius. Orientation towards the pheromone can best be described as orthokinesis where weevils of both sexes show arrestant behavior near the odor sources. This might lead to a modified trapping strategy combining baited and unbaited traps.
