摘  要：
桑天牛Apriona germari(Hope)对补充营养植物的偏好性引起了诸多学者的广泛关注。利用天牛对寄主植物的选择性,开发植物源引诱剂对于天牛的控制具有重要意义。作为植物源引诱剂开发的一个基础工作,本论文研究选择3种主要寄主植物(构树、桑树和杨树)进行桑天牛成虫选择性与取食量的研究;研究显示,构树(Broussonetia parpyrifera(L.)Vent)、桑树(Morus alba L.)和杨树(Populus×canadensis Moench)引诱桑天牛成虫补充营养频率存在显著差异(F=118.9,P<0.01),桑天牛成虫补充营养对于构树具有极明显的选择性;桑天牛对3种植物取食量存在显著差异(F=14.7,P<0.01),桑天牛成虫补充营养时对构树具有明显的偏好性。上述研究为桑天牛成虫诱集捕杀及其引诱剂开发奠定理论基础。同时,为了更好的指导生产实践,本文对两种杀虫剂——虫线清乳油与绿色威雷(触破式微胶囊剂)毒杀桑天牛的效果进行了评价。试验采用林间罩笼方法,测定了两种杀虫剂对桑天牛成虫效果。研究结果表明,虫线清喷施后,显著抑制了桑天牛的取食行为;5 d内桑天牛成虫全部死亡,防治率为100%;绿色威雷喷雾防治桑天牛成虫杀虫作用迅速,150 min内成虫全部死亡,防治效果达100%。上述两种药剂可以作为桑天牛成虫诱集捕杀的候选药剂在生产实践中加以应用。

摘  要：
The preference of Apriona germari( Hope) for various plants has been the subject of many studies. We investigated the feeding frequency and consumption rate of A. germari on three host plants,Broussonetia parpyrifera( L.) Vent,Morus alba L. and Populus × canadensis Moench,in the laboratory. The results show that both the feeding frequency and consumption rate of A. germari differed significantly on these three hosts; feeding frequency( F = 18. 9,P < 0. 01), consumption rate( F = 14. 7,P < 0. 01). The highest feeding frequency and consumption rate was recorded on B. parpyrifera. We also investigated the effectiveness of two pesticides,Chongxianqing( EC) and Luseweilei( contacted- breaking release microcapsules),in controlling A. germari in field experiments. We found that Chongxianqing had a significant effect on A. germari,achieving 100% mortality within 5 d. In addition,Chongxianqing had an obvious inhibitory effect on the feeding behavior of A. germari. Luseweilei was also highly toxic to A. germari,with all tested insects dying within 150 s. We conclude that Chongxianqing and Luseweilei can be used as part of a control strategy for A. germari.
