通过气相色谱分析得出：发生在吉林省东、中、西部３个生态区的一、二化性玉米螟的性信息素组份中的顺反（Ｚ／Ｅ）１２１４∶ＯＡｃ异构体的相对比例没有显著变异。公主岭一化性玉米螟性信息素中含量Ｅ１２１４∶ＯＡｃ的比例为４６１８％，敦化一化性玉米螟为４３４７％；公主岭二化性玉米螟为４５９３％，白城二化性玉米螟为５０５５％。玉米螟发生期以人工配制的不同顺反异构体比例诱芯的田间诱蛾试验证明，诱芯中的反式异构体Ｅ１２１４∶ＯＡｃ组份的比例为３５％时诱蛾活性最高。
Gas chromatography analysis showed that the cis / trans (Z / E) 1214:OAc heterosensor in sex pheromone components of the first and second sex related maize borers occurred in three ecotopes in the east, middle and west of Jilin Province. The relative proportions of the constructs did not differ significantly. Gongzhuling a corn borer sex pheromone content of E 12 12:14:OAc 46.18%, Dunhua a corn borer was 43 47%; Gongzhuling corn borer was 45 93% Baicheng two corn borer 50 55%. In the field trials of the corn borer, artificial entrapment of different cis-trans isomer ratios was used to induce moths in the field to induce the moths to induce entrapment when the proportion of trans-isomer E-12-14: The highest activity.
