近十几年来,我国旱地作物蛴螬的发生为害出现明显上升发展的趋势,粮、棉、油(花生、大豆)、菜、甘蔗、甜菜、林、果及药材等都遭到蛴螬或金龟子的危害。许多地区和单位在开展蛴螬区系调查、研究不同虫种发生规律和防治措施的同时,开始注重蛴螬天敌资源的调查及其应用技术的探讨。土蜂是蛴螬重要的天敌昆虫,种类多,分布广,北方地区许多蛴螬的优势种都发现有土蜂寄生,局部地区寄生率还很高,对蛴螬种群数量具有明显的自然控制作用,引起了广泛的重视。因此,笔者参阅有关资料,编译成篇,扼要介绍它的生物学特性。并对其在生物防治中的应用问题提出几点意见供参考。
In the recent ten years, the incidence of dry mulch in China has risen obviously. The damage of mullet or scarab has been caused by grain, cotton, oil (peanut, soybean), vegetables, sugarcane, beet, forest, fruit and medicinal materials . In many areas and units carrying out the investigation of the mulberry fauna to study the rules and control measures for different species of insects, it began to pay attention to the investigation of natural enemies of mulberry and its application technologies. Bumblebee is an important natural enemies insect, many species, widely distributed, many of the dominant species in northern China are found bumblebees parasitic, parasitic rate is still high in some areas, the population of the emus population has obvious natural control, causing Wide attention. Therefore, I refer to the relevant information, compiled into articles, briefly describes its biological characteristics. And put forward some suggestions on its application in biological control for reference.
