一种系统优化的马铃薯块茎蛾性引诱剂及其应用
摘要：
本发明公开了属于昆虫性信息素制备技术领域的一种系统优化的马铃薯块茎蛾的性引诱剂及其应用。本发明马铃薯块茎蛾性引诱剂包括马铃薯块茎蛾性信息素和马铃薯雌虫腺体提取物，所述马铃薯块茎蛾性信息素为反-4,顺-7-十三碳二烯-1-醇醋酸酯和反-4,顺-7,顺-10-十三碳三烯-1-醇醋酸酯，两者比例为1:4。所述马铃薯雌虫腺体提取物为十六烷酸，并以0.01%-10%的比例添加到马铃薯块茎蛾信息素中。该马铃薯块茎蛾性引诱剂能有效的吸引雄性，以10%比例添加的马铃薯块茎蛾性引诱剂比单纯性信息素诱蛾量提58%，且持效期能够延长到60天，从而能长期降低雌雄虫相遇概率，干扰交配，降低繁殖率，逐步控制害虫种群，从而达到防治害虫的目的。
摘要（英）：

The invention discloses a systematically-optimized phthorimaea operculella sex attractant and application thereof, and belongs to the technical field of insect sex pheromone preparation. The phthorimaea operculella sex attractant comprises a phthorimaea operculella sex pheromone and a female phthorimaea operculella gland extract, wherein the phthorimaea operculella sex pheromone is (Z,E)-trideca-4,7-dien-1-yl acetate and trans-4,cis-7,cis-10-tridecatrien-1-ol acetate, and the ratio of the (Z,E)-trideca-4,7-dien-1-yl acetate to the trans-4,cis-7,cis-10-tridecatrien-1-alcohol acetate is 1:4. Thefemale phthorimaea operculella gland extract is hexadecanoic acid, and added into the phthorimaea operculella sex pheromone according to the ratio of 0.01-10%. The phthorimaea operculella sex attractant can effectively attract male phthorimaea operculella, the phthorimaea operculella attracting amount of the phthorimaea operculella sex attractant which is added according to the ratio of 10% is increased by 58% than that of a pure sex pheromone, the lasting period can be prolonged to 60 days, thus the meeting probability of the female and male phthorimaea operculella can be lowered for a longterm, mating is disturbed, the breeding rate is lowered, pest populations are controlled step by step, and thus the purpose of preventing and controlling pests is achieved.
