摘要:

选用4种肿腿蜂(管氏肿腿蜂、白蜡吉丁肿腿蜂、落叶松吉丁肿腿蜂以及苹小吉丁肿腿蜂),按5种蜂虫比例(0.5:1,1:1,2:1,4:1,8:1),进行新疆野苹果林苹小吉丁套袋防治试验。结果表明:4种肿腿蜂均能成功寄生,而白蜡吉丁肿腿蜂以8:1比例放蜂后30天,虫口校正减退率为65.56%,优于其他处理。将该肿腿蜂再次按5种放蜂比例直接释放在林间,在放蜂后30,45,60天分次调查防治效果,结果表明:以8:1放蜂比例的处理,在第60天校正虫口减退率为50.97%,效果最佳。白蜡吉丁肿腿蜂适合在新疆防治苹小吉丁,且效果良好。

Abstract:

To explore the biological control measure of Agrilus mali Matsumura, four species of bethylid wasp in the genus Sclerodermus (S. pupariae, S. guani and another two species) were used to test their control capacity to pest by bagging with 5 release ratio (parasitoid:host: 0.5:1, 1:1, 2:1, 4:1, 8:1). Results showed that, all four wasps were able to successfully parasitize on A. mali, especialy for S. pupariae, which caused 65.56% reducing rate with release ratio 8:1 in 30 d. Then S. pupariae was tested by directly releasing on the damaged apple trees with the 5 release ratios. After 30, 45 and 60 d, the control effects were checked respectively. The result showed that, the treatment with 8:1 release ratio, after 60 d performed the best, with 50.97% corrected mortality. This research provided a successful case by using bethylid wasps to control A. mali, and offered a reference for appropriate release ratio of S. pupariae in the field.

Key words: Agrilus mali, Sclerodermus spp., biological control, parasitism effectiveness
