This Small Business Innovation Research (SBIR) Phase I project is to demonstrate the feasibility of using a sex-pheromone based mass trapping and mating disruption system for soybean aphids. The soybean aphid, Aphis glycines, is a newly invasive aphid pest, and the only aphid pest on soybeans. This species causes major economic losses either as direct pests or as vectors of plant viruses. This Phase I project will identify and optimize the sex pheromone blend of Aphis glycines, and develop effective controlled release dispensers to be used for disrupting the mating of females, either by classical pheromone mating disruption or by mass trapping. Novel ways of inexpensively procuring large amounts of the pheromone components will also be initiated. The research builds on preliminary studies showing that the soybean aphids can be cultured in the laboratory under controlled conditions to produce sexually active adults. Preliminary experiments have also indicated the production in A. glycines of two compounds known to serve as pheromone components in other aphid species. These compounds evoke upwind flight by males in the wind tunnel, and are attractive to both males and gynoparous female soybean aphids in the field.The commercial application of this project is in the area of pest management for soybean crops. It is expected that the technology developed against the aphid species in soybean may also be applicable against other aphid pests in other economically important crops.

这个小型企业创新研究(SBIR)第一阶段项目是为了论证使用性信息素为基础的大规模诱捕和交配中断系统用于大豆蚜虫的可行性。大豆蚜虫是一种新的入侵害虫，也是大豆上唯一的蚜虫。作为直接害虫或作为植物病毒的媒介，本种造成重大经济损失。这个第一阶段的项目将确定和优化蜜蜂甘氨酸的性信息素混合物，并开发有效的控制释放分配器，用于通过经典的信息素交配中断或通过质量诱捕来扰乱雌性交配。还将启动以廉价方式获得大量信息素成分的新方法。这项研究建立在初步研究的基础上，该研究表明，大豆蚜虫可以在实验室中在受控条件下进行培养，以产生性行为活跃的成虫。初步实验还表明，在大豆根结线虫体内产生了两种已知的化合物，它们在其他种类的蚜虫中用作信息素成分。这些化合物在风洞中激发雄虫迎风飞行，对田间雄虫和雌虫都有诱集作用。该项目在大豆作物病虫害防治领域具有商业应用价值。预计开发的针对大豆上的蚜虫物种的技术也可以适用于其他重要经济作物上的其他害虫。
