Mating disruption is achieved by releasing synthetic pheromones into crop systems to disrupt natural mating behavior of targeted pests. Dispensers of synthetic pheromones are deployed in various crops with the intent of limiting males from finding females thereby reducing or delaying mating to lower pest populations over time. Codling moth (CM) (Cydia pomonella L.) and oriental fruit moth (OFM) (Grapholita molesta) (Busck) are worldwide pests of pome and stone fruits. We investigated the hypothesis that pupal exposure to species-specific sex pheromones affects subsequent mate-finding ability, mating behavior, and reproductive output of adult CM and OFM. Laboratory experiments revealed that pheromone exposure during the pupal stage significantly impacts CM reproductive output and mate-finding, whereas these effects were not observed with OFM. Our findings suggest that targeted deployment of pheromones to cause pupal exposure may enhance control of certain species such as CM.
性信息素干扰法是通过向作物系统中释放合成性信息素来破坏目标害虫的自然交配行为。合成性信息素的 dispenser 被部署在各种作物中，目的是限制雄性找到雌性，从而随着时间的推移减少或延迟交配，以降低害虫数量。苹果蠹蛾（CM）（苹果小卷蛾）和东方果实蛾（OFM）（桃小食心虫）是全球范围内梨果和核果的害虫。我们研究了这样一个假设，即蛹期接触物种特异性性信息素会影响成年苹果蠹蛾和东方果实蛾随后的寻找配偶能力、交配行为和繁殖产出。实验室实验表明，蛹期接触性信息素会显著影响苹果蠹蛾的繁殖产出和寻找配偶的能力，而东方果实蛾未观察到这些影响。我们的研究结果表明，有针对性地部署性信息素以导致蛹期接触，可能会加强对某些物种（如苹果蠹蛾）的控制。
