摘　　要：选用乐果农药对寡毛类白颈环毛蚓（Ｐｈｅｒｅｔｉｍａｃａｌｉｆｏｒｎｉｃａ）、鞘翅类金龟甲科（Ｓｃａｒａｂｅｉｄａｅ）幼虫和等足类鼠妇虫科（Ｐｏｒｃｅｌｉｏｎｉｄａｅ）动物进行染毒试验，研究农药污染对土壤动物呼吸强度的影响．结果表明，乐果农药毒性对土壤动物呼吸强度具有明显抑制作用，其呼吸代谢强度随农药处理浓度的增加与染毒历时的延长而减弱．高浓度、短时间或低浓度、长时间的染毒均能导致土壤动物的死亡．Simulating tests of Pheretima californica ,scarabeidae and porcellionidae were made to study the effect of pesticide pollution to respiration intensity of soil animal.The results shows the toxicity of dimethoate pesticide constrains the respiration intensity of soil animal obviously,which weakened with the increasing of pesticide treating concentration and prolonging of poisoning time, and poisoning of both high concentration,short time and low concentration,long time can lead animals to death.
