摘要: 提取和鉴定了淡剑袭夜蛾(Sidemia depravata)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(Z914:Ac)和顺9,反12十四碳烯醇醋酸酯(Z9E1214:Ac).在这2种化合物配制的二元组份诱芯中,以Z914:Ac/Z9E1214: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.

Abstract: (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 Aand Bin5 different ratios were tested in the fields for evaluating their attractiveness to male LGCW. Water pool traps with red septa containing5:5 and 6:4 of Aand Bcaught significantly more male LGCW than traps containing 9:1, 8:2 or 7:3 of Aand B.

Key words: Sidemia depravata, Sex pheromone, Turfgrass, (Z)-9-tetradecenyl acetate, (Z,E)-9,12-tetradecadienyl acetate, Cu stress, Cd stress, nitric oxide, tomato, glutathione, phytochelatin.
