桃红颈天牛综合治理技术概述

Summary of IPM of Aromia bungii Faldermann

系统总结国内外有关桃红颈天牛的防治技术,从物理防治、化学防治和生物防治3个方面进行阐述,重点阐述最具生产应用价值的防治技术。最后提出以物理防治为主,生物防治为辅的综合治理措施。即在成虫羽化前用薄膜包扎法阻止天牛成虫产卵,同时设置诱饵树,集中消灭前来产卵的雌虫及其所产的卵,刺杀已孵化的低龄幼虫,8—9月释放管氏肿腿蜂来防治天牛低龄幼虫,在第2年春季注射斯氏线虫或释放花绒寄甲防治天牛幼虫和蛹。上述方法连续进行2年,每年1次,即可将桃红颈天牛的种群数量控制到较低水平。

This paper summarized the control technology of red-necked longhorn beetles, tocused on expounding the physical control, chemical control and biological control of the pests, and finally proposed the IPM of Aromia bungii dominated by physical control and supplemented by bio-control. The main steps were described as follows： Firstly, the trunks or branches were bound up with film. At the same time, a few of the hosts were not handled to allure the female of the beetles to lay eggs, and then the eggs or the young larvae were destroyed. After that, the parasitoid Sclerodermus guani were released to control the larvae in August or September. Finally, in the spring of the second year, the parasitoid Dastarcus helophoroides were released to control the pupa of the longhorn beetles, or the nematodes were injected to control the larvae. The population of the beetles could be controlled to an obviously lower level after two years by this way.
