摘要：

为了弄清侧柏蛀干害虫引诱剂对柏树蛀干类害虫的引诱效果及其种群动态，笔者于2009年和2010年的3-7月柏树蛀干类害虫发生期，在天坛公园古柏林进行引诱剂诱捕柏树蛀干害虫的试验，并分析了诱捕期蛀干害虫的种群变化与温度的关系。结果表明，侧柏蛀干害虫引诱剂对柏树蛀干害虫有较好的诱捕作用，可以诱集到危害古柏的蛀干害虫主要有3种，分别是双条杉天牛、柏肤小蠹、长蠹。双条杉天牛越冬代成虫的羽化出蛰时间最早，其次为长蠹、柏肤小蠹，这3种昆虫的种群变化受日最高气温的影响明显。可见，该引诱剂可以持续监测柏树林间主要蛀干害虫成虫的发生时间、发生量和种群动态，连续使用还能显著降低林间蛀干类害虫的虫口密度，为监测、预报和控制柏树蛀干害虫提供直接、客观的依据。

Abstract:

Attractant was used to trap stem borers in temple of heaven, Beijing to testify the effect of borer attractant on stem borers of Platycladus orientalis (Linn.) Franco during its active stage from 2009 to 2010. And an experiment was conducted to study the effects of temperature on trap efficiency. Results showed that the stem borer attractant had good effect which could attract 3 species of stem insects, including Semanotus bifasciatus Motschuisky, Phloeosinus perlatus Chapius and Bostrychidac sp.. The long horned beetles adults was the earliest active, secondly Bostrychidac sp. and Phloeosinus perlatus Chapius. The 3 insects number of trap were obviously effected by the daily maximum temperature. Accordingly, the population dynamic of Semanotus bifasciatus Motschuisky, Phloeosinus perlatus Chapius and Bostrychidac sp., and the relation of daily maximum temperature. It will play an important role in monitoring and controlling the population density of Semanotus bifasciatus.
