摘　　要：苹果蠹蛾(Cydia pomonella)是危害果树生产的重大农业害虫,是世界性检疫有害生物。本文通过苹果蠹蛾对9个梨品种果实的产卵选择与生长发育试验,获取了苹果蠹蛾在不同梨品种上的主要生物学参数。结果表明,不同梨品种对苹果蠹蛾的产卵量、卵孵化率、幼虫蛀果率和卵期等有显著影响。在9个梨品种中,成虫对乳山小香梨(8.64粒/果)产卵偏好性最高,高密马蹄黄(5.07粒/果)次之;冠县大梨水和秋洋梨的卵孵化率较低,分别是6.95%和8.04%;高密马蹄黄的幼虫蛀果率最高为28.89%,乳山小香梨次之,为19.44%。综合得出苹果蠹蛾在秋洋梨和冠县大梨水上的适应性低,在高密马蹄黄和乳山小香梨上的适应性高。本文研究结果为田间持续有效控制苹果蠹蛾提供了理论支持。Codling moth is a major agricultural pest affecting the production of fruit trees and is a worldwide quarantine pest.In this paper,the main biological parameters of codling moth on different pear varieties were obtained by egg-laying selection and growth and development experiments of codling moth on the fruits of nine pear varieties.The results showed that different pear varieties have a significant effect on the egg production,egg hatching rate,larval fruit-boring rate and egg stage of codling moth.Among the nine pear varieties,adult codling moth had the highest egg-laying preference for Rushan fragrant pear(8.64 eggs/fruit),followed by Gaomi pear(5.07 eggs/fruit);The egg hatching rates of the Guanxian pear and the Qiuyang pear were relatively low,being 6.95%and 8.04%respectively;The larval fruit-boring rate of Gaomi pear was the highest at 28.89%,followed by Rushan fragrant pear,which was19.44%.Overall,it can be concluded that codling moth had low adaptability on Qiuyang pear and Guanxian pear,but high adaptability on Gaomi pear and Rushan fragrant pear.The research results of this article provide theoretical support for the sustained and effective control of codling moth in the field.
