摘  要:
参考FAO推荐的熏蒸剂毒力测定方法,测定了甲酸乙酯对4种不同磷化氢抗性水平的赤拟谷盗(Tribolium castaneum(Herbst))品系的毒力。主要结果为甲酸乙酯对4个磷化氢抗性系数分别为1、3、170和247倍的赤拟谷盗品系的LD50值相应地为17.354L/m3、18.776L/m3、20.464L/m3和21.470 mL/m3。结果表明,不同磷化氢抗性的赤拟谷盗品系对甲酸乙酯的敏感相似,对磷化氢具有明显抗性的赤拟谷盗对甲酸乙酯未表现出抗性。

摘  要:
Toxicity of ethyl formate on adults of Tribolium castaneum(Herbst) strains with different resistant to phosphine was bio-assayed referenced to FAO recommended method.The results involved in that the LD50 of ethyl formate to different phosphine resistance strain of Tribolium castaneum,in the resistance factor of 1、3、170 and 247 folds,was 17.354mL/m3、18.776L/m3、20.464L/m3 and 21.470 mL/m3 relatively.The results indicate that there was almost no different on sensitive to ethyl formate among of different phosphine resistant strains.And the resistant strain of Tribolium castaneum to phosphine had no cross resistance to ethyl formate
