黑龙江垦区常见的地蛆种类是种蝇和葱蝇的幼虫,主要为害白菜、萝卜、葱、蒜。此害虫连年发生,严重影响菜类的产量和品质。目前用化学药剂防治菜地地蛆已成为蔬菜生产上不可缺少的常规措施。连年施用化学药剂,不但影响蔬菜质量,而且污染了环境。由此可见,在蔬菜上探讨使用生物农药防治地蛆是十分必要的。 The common maggot species in Heilongjiang reclamation area are larvae of species flies and onion flies, which are mainly responsible for cabbage, radish, onion and garlic. This pest occurs year after year, seriously affecting the yield and quality of vegetables. At present, the use of chemical agents to prevent and treat vegetable maggots has become an indispensable routine measure for vegetable production. Year after year of chemical agents, not only affect the quality of vegetables, but also pollute the environment. Thus, it is necessary to explore the use of biological pesticides in the control of maggot in vegetables.
