Laboratory bioassays were conducted to determine the effects of two carbamates, carbofuran (an acetylcholinesterase inhibitor) and fenoxycarb (a juvenile hormone analog), on survival and infectivity of the infective juveniles (IJ) of Steinernema feltiae Umeå strain and Steinernema carpocapsae All strain. Both insecticides caused mortality of IJ in a dose-related fashion. The two nematode species were equally sensitive to fenoxycarb (LD ca. 0.03mg/ml). Whereas IJ of S. feltiae were several orders of magnitude more sensitive to carbofuran (LD </= 0.2 mug/ml) than to fenoxycarb, S. carpocapsae IJ displayed approximately the same degree of sensitivity to carbofuran (LD 0.01-0.03 mg/ml) as they did toward fenoxycarb. Toxicity of the carbamates was the same at all exposure periods from 24 to 168 hours' duration. Determinations of infective doses of nematodes required to cause 50% mortality of Galleria mellonella larvae showed that the infectivity of IJ that survived exposure to either of the two carbamates was not compromised by treatment.
进行了实验室生物测定，以确定两种氨基甲酸酯类农药，即克百威（一种乙酰胆碱酯酶抑制剂）和苯氧威（一种保幼激素类似物）对斯氏线虫瑞典株和小卷蛾斯氏线虫全株感染性幼虫（IJ）存活和感染性的影响。两种杀虫剂均以剂量相关的方式导致IJ死亡。这两种线虫对苯氧威同样敏感（致死剂量约为0.03mg/ml）。虽然斯氏线虫的IJ对克百威（致死剂量≤0.2μg/ml）的敏感性比对苯氧威高几个数量级，但小卷蛾斯氏线虫的IJ对克百威（致死剂量0.01 - 0.03mg/ml）的敏感程度与对苯氧威的敏感程度大致相同。在24至168小时的所有暴露时间段内，氨基甲酸酯类农药的毒性相同。对导致大蜡螟幼虫50%死亡所需的线虫感染剂量的测定表明，暴露于两种氨基甲酸酯类农药之一后存活的IJ的感染性并未因处理而受到损害。
