Abstract:

Males of Anthonomus grandis grandis Boheman destined to enter diapause are capable of inseminating females that can in turn produce fertile eggs. However, these males have greatly reduced mating vigor and do not compete as well for virgin females as reproductive males do. Therefore, populations in which a large percentage of the weevils are destined to enter diapause may be more vulnerable to the releases of sterile laboratory-reared insects for decreasing the chances that native overwintered females would lay fertile eggs prior to mating in the spring. This approach, when used in combination with the technique of disruption of pheromonal communication, should increase the effectiveness of the disruption technique.
