室内条件下,研究了不同寄主植物上桃蛀果蛾Carposina sasakii Matsumura寄生蜂种类、寄生率以及温度对苹果桃蛀果蛾及其寄生蜂章氏小甲腹茧蜂Chelonus(Microchelonus)zhangi滞育后发育的影响。结果表明,章氏小甲腹茧蜂寄生于苹果、枣、酸枣和山楂上的桃蛀果蛾;中国齿腿姬蜂Pristomerus chinensis Ashmead寄生于枣、酸枣和山楂上的桃蛀果蛾;杏寄主上未发现寄生蜂。不同寄主植物上的寄生率差异显著,其中章氏小甲腹茧蜂在苹果桃蛀果蛾的寄生率最高,为16.45%,在山楂桃蛀果蛾的寄生率最低,为1.58%;中国齿腿姬蜂在酸枣桃蛀果蛾的寄生率最高,为5.05%,在山楂桃蛀果蛾寄生率最低,为1.09%。苹果桃蛀果蛾及章氏小甲腹茧蜂越冬幼虫开始发育至成虫羽化阶段的发育起点温度分别为7.27℃和10.96℃,有效积温分别为208.86DD和166.73DD。
Under laboratory conditions, the species, parasitism and temperature of the parasitoid Carposina sasakii Matsumura on different host plants were studied. After the diapause of the apple peach moth and its parasitic Chelonus (Microchelonus) zhangi Developmental effects. The results showed that the B. subgenus was parasitic on the apple, jujube, jujube and hawthorn of the peach moth; Chinese Prongus serrata Pristomerus chinensis Ashmead parasitic jujube, jujube and hawthorn peach moth; apricot host No parasitic wasp found on The parasitism rates of different host plants were significantly different. Among them, the parasitism rate of Caragana korshinskii was 16.45% in apple peach moth and the lowest was 1.58% in Hawthorn peach moth; The parasitism rate of Hyphan wasps was the highest at 5.05% in the fruit jujube moth and the lowest was 1.09% in the hawthorn moth. The starting temperature of overwintering larvae of apple peach moth and Chamaejakovs was 7.27 ℃ and 10.96 ℃, respectively. The effective accumulated temperature was 208.86DD and 166.73DD respectively.
