在开展天敌昆虫资源调查和保护利用工作中,革翅目的原螋、蠼螋、肥螋等是有待研究的捕食性天敌。近年我们对日本原螋Labidura japonica de Haan进行室内饲养观察,但工作开始时感到虫源较为困难,在20瓦黑光灯下虽可见到一些,但有的年份扑灯时期较晚,数量也不多;同时,落入集虫盒内药液中的成虫容易死亡,故不适作饲养用虫。经过多次试验,证明在诱捕器内投放饵料诱捕日本原螋成本低廉,方法简便,效益较为理想,在短期内可捕获大量的活虫供饲养观察。本文简要介绍诱捕方法、诱捕效果及应注意的问题。
In carrying out natural enemies of insect resource investigation and protection of the use of work, the purpose of leather-winged 螋 蠼, 蠼 螋, fat 螋, etc. are to be studied predatory natural enemies. In recent years, we conducted an indoor rearing observation on Labidura japonica de Haan, but at the beginning of the work, we found it difficult to identify the source of insects. Although we can see it under the 20-watt black light, some of them were not available for a long time ; At the same time, the adults falling into the collection box liquid medicine easily die, it is not suitable for feeding insects. After several tests, it has been proved that the bait trapped in the trap has the advantages of low cost, simple and convenient operation, and good harvesting benefits. In the short term, a large amount of live insects can be captured for observation. This article briefly describes the trapping method, trapping effect and should pay attention to the problem.
