摘要
为了摸清松墨天牛的羽化高峰期,更好地防治松材线虫病,采用在典型样地悬挂诱捕器的方法,于2018年5-10月对大连市甘井子区、中山区典型样地的松墨天牛种群活动情况进行了调查。结果表明:样地发现松墨天牛、褐梗天牛和小灰长角天牛3种蛀干害虫;松墨天牛的羽化高峰期在6月末至7月上中旬,6-7月的虫口密度占全年的80%以上,为科学有效地监测松褐天牛的发生规律,预测松材线虫病的发生与及时有效地控制其蔓延提供科学依据。
In order to find out the peak period of adult emergence of Monochamus alternatus and control pine wilt disease effectively,traps were hanging in typical plots from May to October in 2018 to investigate the population activity of M.alternatus in Ganjingzi District and Zhongshan District of Dalian City.The results indicated that three kinds of trunk borers were detected in plots.They are M.alternatus,Arhopalus rusticus and Acanthocinus griseus;the peak period of adult emergence was from the end of June to middle July.From June to July,insect population density accounted for more than 80%of the whole year.The results provided basis for scientific and effective monitoring of the occurrence regularity of M.alternatus and predicting the occurrence of pine wilt disease and controlling its spread in time.
