Abstract

The leafroller species, Cnephasia jactatana Walker, is an important pest of kiwifruit in New Zealand. The effect of mating delay on its reproductive performance was investigated in the laboratory to provide information for the development of pheromonal pest control measures such as mating disruption. Reproductive performance of both sexes is adversely affected by mating delay. Females are more severely affected by mating delay than males in terms of reproductive potential. Delaying mating in females for 3 and 4 d reduced the reproductive potential by 29 and 88%, respectively. It is suggested that mating disruption may have potential for the control of this species.

摘要

卷叶蛾物种，即苹果全小卷蛾（Cnephasia jactatana Walker），是新西兰猕猴桃的一种重要害虫。在实验室中研究了交配延迟对其繁殖性能的影响，以提供信息用于开发诸如干扰交配等性信息素害虫防治措施。交配延迟对两性的繁殖性能均有不利影响。就繁殖潜力而言，雌性比雄性受交配延迟的影响更严重。雌性交配延迟3天和4天，其繁殖潜力分别降低了29%和88%。建议干扰交配可能对该物种的防治具有潜力。
