摘　　要： 提取和鉴定了淡剑袭夜蛾 (Sidemiadepravata)的性信息素主要组分 ,并进行了田间试验 .结果表明 ,雌蛾性腺体提取物中主要性信息素组分为顺 9 十四碳烯醇醋酸酯 (Z9 14∶Ac)和顺 9,反 12 十四碳烯醇醋酸酯 (Z9E12 14∶Ac) .在这 2种化合物配制的二元组份诱芯中 ,以Z9 14∶Ac/Z9E12 14∶Ac =5 / 5和 6 /4比例配制成的诱芯诱蛾效果较好 ,田间诱蛾量显著高于以 1∶9、2∶8和 3∶7比例配制的诱芯 . Z) 9 tetradecenyl acetate (A) and (Z,E) 9,12 tetracecadienylacetate (B) were found in sex pheromone gland extracts of female lawn grass cutworm(LGCW), Sidemia depravata ,with single gland extract technique by gas chromatography. Field trapping tests were conducted in tall fescue fields in Yangzhou City, Jiangsu Province of eastern China. Baits containing components A and B in 5 different ratios were tested in the fields for evaluating their attractiveness to male LGCW. Water pool traps with red septa containing 5∶5 and 6∶4 of A and B caught significantly more male LGCW than traps containing 9∶1, 8∶2 or 7∶3 of A and B.
