应用北美小蠹信息素对中国一些小蠹的引诱研究

A Study on Luring Some Beetles of China by Using Pheromones of North American Beetles

应用南松大小蠹Ｄｅｎｄｒｏｃｔｏｎｕｓｆｒｏｎｔａｌｉｓ、西松大小蠹Ｄ．ｂｒｅｖｉｃｏｍｉｓ，山松大小蠹Ｄ．ｐｏｎｄｒｏｓａｅ，云杉八齿小蠹Ｉｐｓｔｙｐｏｇｒａｐｈａｓ和Ｉ．ｓｐ的信息物，对华山松的小蠹和光臀八齿小蠹Ｉ．ｎｉｔｉｄｕｓ进行了三年的引诱试验。结果表明；云杉八齿小蠹信息素用于光臀八齿小蠹成虫诱集是成功的，可用于预测预报，也可配合防治处理；几种美洲的大小蠹信息素对华山松大小蠹Ｄ．ａｒｍａｎｄｉ等多种小蠹的引诱只可用以进行分布预测及成虫发生期预测；对小蠹天敌也有一定引诱效果。

The pheromones of Dendroctonus frontalis, D. brevicomis, D. Pondrosae, Ijps tygraphus and I. sp have been used to attract bark beetles of Pinus armandi and I.nitidus for three years. The test results are as follows. The pheromone of Ips typographus is successfully applied to attract I. nitidus adult, which can be used to predict and forecast as well as help to control insect occurence. The attraction of several American Dendroctonus' pheromones on D. armandi and other divers bark beetles is only used to predict distribution and adult occurence, and it can lure bark beetle's enemies as well.
