摘　　要：为弄清松褐天牛的羽化规律,2020~2021年连续两年4-10月在长沙县布设松褐天牛诱捕器850套,收集并统计不同时段诱捕器中天牛成虫的数量。对诱集到的松褐天牛成虫数量用SPSS 19.0等软件进行统计分析,结果表明:长沙县4月12日-10月8日都能诱捕到松褐天牛成虫;2020年7月7日,松褐天牛累计羽化率超过全年羽化的77%;2021年7月23日,松褐天牛累计羽化率为全年羽化率的79.0%;不同时间段松褐天牛的羽化量差异显著(P<0.05)。每年4-10月为湖南省长沙县松褐天牛的自然羽化期,其羽化受多种因素影响,羽化高峰期变化较大。In order to find out the eclosion rule of MonocCamus alternatus,850 sets of traps were set in the center of Bursaphelenchus xylophilus from April to October in 2020 and 2021 in Changsha County in Hunan Province,collecting and counting the number of adult Monochamus alternatus in the traps at different time periods from April to October each year.SPSS 19.0 and other softwares were used to analyze the number of trapped adult of Monochamus alternatus.The Results showed that adult Monochamus alternates could be trapped from April 12th to October 8th in Changsha County.The cumulative emergence rate of Monochamus alternatus exceeded 77%of the annual emergence rate on July 7th,2020,while the cumulative emergence rate of Monochamus alternatus was 79.0%of the annual emergence rate on July 23 rd,2021.The eclosion amount of Monochamus alternates in different period was significantly different(P<0.05).The natural eclosion period of Monochamus alternatus in Changsha County of Hunan Province was from April to October.Its eclosion was affected by many factors,and the peak period of eclosion changed greatly.
