药剂喷施饵木防治双条杉天牛成虫的试验

Chemical control on Semanotus bifasciatus (Motschulsky) with Trap Log

2007年3月在室内进行药效筛选试验,结果表明,阿维·毒、毒死蜱、高效氯氟氰菊酯3种药剂喷施侧柏饵木均能杀死双条杉天牛成虫,毒死蜱作用最快,5d完全死亡率达到94.7%。2008年3月选用高效氯氰菊酯、阿维菌素·毒死蜱、丙溴磷进行了野外试验,结果表明,3种不同药剂防治效果差异显著,同种药剂不同浓度之间防治效果差异不显著,高效氯氰菊酯2000倍液效果最好。喷施高效氯氰菊酯、阿维菌素·毒死蜱不影响饵木的诱集效果。丙溴磷对饵木引诱效果产生影响,其机制机值得得进一步探讨。

A preliminary test on the toxic effects of abamectin＋chlorpyrifos, EC, chlorpyrifos and lambda cyhalothrin on the Semanotus bifasciatus （Motschulsky） was carried out in Beijing Forestry University Forest Protection Laboratory in March 2007. The results showed that all the 3 pesticides could kill the adults of Semanotus bifasciatus （Motschulsky）, but the effect of the chlorpyrifos was the most obvious, and the mortality rate in 5 days reached to 94.7%. Then field exPeriments were done with the Beta cypermethrin, abamectin＋chlorpyrifos, E.C and profenofos in Mushi Forest Farm, Shandong province in 2008. The results indicated that the Beta cypermethrin 2000 times liquid was the most effective and economical, and that the pesticides did not change the attractive effect of trap log.
