草蛉是防治蚜虫、棉铃虫、红蜘蛛和介壳虫等害虫的一种较有前途的天敌,近年来已引起各地重视。利用自然界发生的草蛉防治害虫,往往受发生时期、数量、种类和虫态的限制,在防治工作中不能争取主动。通过人工大量饲养、繁殖和释放,就有可能有计划地利用草蛉来防治害虫。两年来,我们通过研究和在农村中的实践,初步总结出了一套经济简便,在当前农村条件下比较切实可行的饲养繁殖草蛉的技术。这些技术,便于土法上马、广泛开展养蛉、放蛉防治害虫的群众运动。
Grass mullet is a more natural predator against pests such as aphids, cotton bollworm, red spider mite and scale insects, and has drawn great attention in recent years. Control of pests by grass weeds occurring in nature is often limited by the occurrence period, quantity, species and state of insects, and can not be taken as the initiative in prevention and control work. By artificially breeding, breeding and releasing in large quantities, it is possible to planted grass breeders to control pests. In the past two years, through our research and practice in rural areas, we have initially summarized a set of technologies that are simple and economical to raise breeding grass in the current rural areas. These technologies make it easy for the soil law to be launched and carry out extensive mass support campaigns to prevent and control pests.
