4种常用农药对2种天敌蝽的药害影响

笔者探究了4种不同农药对两种蝽的药害影响，结果表明：氯氰、辛硫磷、吡虫啉、氰戊菊杀虫剂对2种蝽（蠋蝽和一种益蝽）皆有较强药害，释放于自然环境后该2种天敌蝽存活与繁殖受到明显抑制；除草剂类农药虽然对2种天敌蝽没有直接药害影响，但施用除草剂后对自然环境中的农作物具有毒性作用，2种蝽的存活与繁殖同样受到影响。因此，要2种蝽在自然环境中得以较好生存与自然繁殖，必须规范释放地区的农药管理，加强绿色环保理念教育与引导，才能建设稳定的立体生防系统。

Effects of Four Commonly Used Pesticides on Two Kinds of Arma Hanh

The authors explored the effects of four pesticides on two kinds of Arma Hanh. The results showed that cypermethrin, phoxim, imidacloprid and cyanide chrysanthemum had strong influence on the two kinds of Arma Hanh (Armachinensis and Picromeruslewisi), after the two kinds of Arma Hanh were released in natural environment, their survival and reproduction were significantly inhibited. Though herbicide pesticide had no direct influence on the two kinds of Arma Hanh, there were some toxic effects on crops in natural environments, so the Arma Hanh could hardly survive. Therefore, to improve the survival and natural reproduction of Arma Hanh in natural environment, we must strengthen the pesticide management, and the concept of green environmental protection, education and guidance, thus to build stable stereoscopic biocontrol system.
