中文摘要：
研究甲酸乙酯和甲酸对离体玉米象Sitophilus zeamais(Motschulsky)酯酶和乙酰胆碱酯酶(AChE)的抑制作用，结果表明甲酸乙酯对离体的玉米象酯酶和AChE没有抑制作用，并且甲酸对玉米象酯酶和AChE的抑制中浓度远远高于甲酸乙酯对玉米象的致死中浓度，说明甲酸对玉米象这两种酶的抑制作用不是甲酸乙酯杀虫的主要机理。
英文摘要： The inhibition of ethyl formate and formic acid to esterase and AChE of Sitophilus zeamais (Motschulsky) in vitro was studied. The results showed that ethyl formate can not inhibit esterase and AChE of S. zeamais in vitro, and the I50 of formic acid to esterase and AChE was much higher than the LC50 of the ethyl formate to S. zeamais. It revealed that the inhibition of formic acid was not the major mechanism of ethyl formate killing S. zeamais.
