摘要
采用普通船型诱捕器,对落叶松毛虫人工合成性引诱剂不同载体诱蛾效果进行了林间应用研究。结果表明:常规橡胶塞诱芯诱蛾时间多为3～5 d,之后需要更换新诱芯,诱蛾规律性不强,无法准确判断虫情发生趋势。而PVC微管型诱芯诱蛾效果明显优于前者,诱蛾期长达1个月,落叶松毛虫成虫发生趋势明显,为掌握松毛虫发生趋势提供科学依据,同时还大大节省人工及材料成本。
By use of the ordinary ship type trap,the attracting effect of synthetic sex attractant for Dendrolimus superans has been tested in the field with different carriers.The results show that the conventional rubber lure can lure moth for 3~5 days,a new lure need to be replaced,and trap law isn＇t strong,and the pest occurrence tendency can＇t be accurately judged.But the luring effect of PVC microtubules type lure is better than the former,with luring period reaching up to one month.And the occurrence tendency of Dendrolimus superans adults is obvious.It can provide the scientific basis for mastering the occurrence trend of Dendrolimus superans adults,and save the costs of labors and materials greatly.
