武夷山风景区松墨天牛的发生与分布

The Occurrence and Distribution of Monochamus alternatus Hope in Wuyi Scenery Spot

摘要: 采用林间调查和FJ-Ma-02型引诱剂诱捕相结合的方法,研究了松墨天牛在武夷山风景区的发生与分布.结果表明,松墨天牛在武夷山风景区主要是零星分布,多集中发生为害单株濒死或枯死松树上,以及被马尾松毛虫为害后的局部林分,局部发生区虫口密度高,但总体虫口密度不高;成虫在风景区1年有2个发生高峰期,分别在5月中旬到6月上旬和6月下旬到7月中旬,两次高峰期诱捕到的成虫占总诱捕量(125头)的90.4%;诱捕结果还表明,武夷山风景区一般海拔高程在200~400 m之间,在低海拔地理条件下松墨天牛均有发生,受海拔高程的影响不显著;松墨天牛成虫捕获量与气压、温度、最高与最低温差、相对湿度以及降水等5个气象因子之间均没有显著的相关性..

Abstract: The methods of survey in forests and FJ-Ma-02 attractant were applied to research the occurrence and distribution of Monochamus alternatus hope.The results showed that Monochamus alternatus hope had a low population density in Wuyi scenery spot,and the population of adults had 2 peak time in a year,one was from the middle ten days of May to the first ten days of June,the other one was from the last ten days of June to the middle ten days of July.In the 2 peaks the numbers of trapped adults was 90.4 percent ...
