摘要
应用M99-1引诱剂监测松林蛀干害虫的种群动态,结果表明松林间的蛀干害虫优势种群有9种,其中天牛科2种、象甲科3种、小蠹科4种,诱集量分别占总诱集量的22.3%,29.7%和48.0%。不同林龄的林分蛀干害虫诱集量存在显著差异,过熟林中象甲科、小蠹科成虫诱集量显著大于中龄林,但天牛科差异不显著;2006—2008年,连续3 a在同一林地使用M99-1引诱剂诱杀松林蛀干害虫结果表明,不同年份蛀干害虫诱集量存在差异,每年诱集量占总诱集量的比例分别为36.4%,42.6%和21.0%。利用监测结果,对龙游松墨天牛及其它优势种群的成虫动态进行了分析,并提出相应的防控建议。
The results of the monitoring showed that there were 9 dominant borer populations in the pine forests including 2 longhorn beetles ( Cerambycidae), 3 weevils (Curculionidae) and 4 bark beetles ( Scolytidae) ,which occupied 22. 3% ,29.7% and 48, 0% of all the borers trapped. The age of the forests affected significantly the trapping amount with M99_ 1 attractant and more weevils and bark beetles were attracted in old forests than in middle age forest, but there was no significant difference in longhorn beeries in two types of forests. Between 2006 and 2008, the annual trapping amount of adults varied, which occupied 36. 4% (2006) ,42. 6% (2007)and 21.0% (2008)of the total. Based on this study, adult population size dynamics of Monochamus alternatus and other major pests were monitored and the control methods against the stem borers were put forward.
