摘　　要：为更好地对松墨天牛进行监测和诱杀,研究使用标记重捕法进行松墨天牛监测并选取3种引诱剂在林间诱捕,结果表明:在羽化初期诱集到的雄虫数量高于雌虫;添加天牛信息素可以有效提高引诱剂的效果,引诱到的雌虫数量高于雄虫;试验地内标记回捕率11.56%,占总诱捕量的6.45%,估算试验地内松墨天牛的种群数量为9 330头,雌虫4 582头,雄虫4 748头;北京中捷四方引诱剂的诱集数量、诱集纯度、诱集时效在3种引诱剂中最优,但对羽化1—20 d天牛的诱集效果不如杭州费洛蒙。以松墨天牛监测为目标时可以使用北京中捷四方引诱剂,以松墨天牛诱杀为目标时建议使用杭州费洛蒙引诱剂。To monitor and control Monochamus alternatus adults efficiently,we selected three common kinds of attractants on market to trap the adults in forest via a“mark-release-recapture”technique.The result was as follows:At the early stage of emergence,more male beetles trapped than females.Adding longicorn pheromone could effectively improve the effect of attractants,and more female beetles was trapped than males.There captures accounted for 6.45%of the total trappings.With 11.56%recapture rate,we estimated a total of 9330 adults(4582 males and 4748 females)within the experimental field.The trapping quantity,purity and timeliness of attractants produced by PEROBIO were the best winsome,but worse trapping effects on 1—20 d emerging adults than Hangzhou Pheromone.PEROBIO attractant could be used in monitoring M.alternatus,and Hangzhou Pheromone attractant could be recommended in trapping M.alternatus.
