Description

一种化合物及其制备方法以及其在制备桃红颈天牛成虫引诱 剂中的应用
技术领域
本发明涉及一种杀虫技术领域，具体涉及一种化合物及其制备方法以及其在制备桃红颈天牛成虫引诱剂中的应用。
背景技术
桃红颈天牛属鞘翅目天牛科，分布于浙江、辽宁、内蒙古、河北、河南、山西、陕西、山东、江苏、湖北、福建、广东、广西、四川、甘肃等省、自治区。寄主有梅、李、杏、桃、樱桃、苹果、梨等果树，尤以核果类果树受害较重。该虫二年发生一代，以各龄幼虫在蛀食的虫道内越冬。六、七月间成虫发生，成虫寿命约10天左右，交尾后产卵于主干或主枝枝杈缝隙处。卵经8-12天孵化为幼虫。初孵幼虫在皮层下食害，成长后钻入木质部为害，并经常向外排出虫粪，被害处容易流胶。幼虫蛀入果树皮层和木质部为害，向下蛀成弯曲的虫道，隔一定距离向外蛀一排粪孔，由此排出粪便和木屑，堆积于地面或枝干上，造成树干中空，树势衰弱，甚至枯死，由此可见桃红颈天牛对果树、林木生产及城市园林绿化构成了巨大威胁。
目前，对于桃红颈天牛的防治技术有植物检疫、物理机械防治、化学防治、生物防治，但在生产实践中桃红颈天牛的防治仍以传统的化学防治为主，过度依赖化学农药，存在污染环境、杀伤天敌、危害人类健康等问题。

低温配置L-酒石酸酯和四异丙氧基钛络合物，滴加反-2-,顺-6-壬二烯醛，搅拌反应1小时，再加入过氧叔丁醇溶液；反应完全后，经后处理得到式I所示的化合物，
本发明还提供了一种式I所示的化合物在制备桃红颈天牛成虫引诱剂中的应用；
优选的，所述桃红颈天牛成虫引诱剂还包括植物源化合物。
