SBIR Phase I: Development of a Sex Pheromone-Based System to Suppress Populations of Soybean Aphids

这个小企业创新研究（SBIR）第一阶段项目是为了证明使用基于性信息素的大规模诱捕和交配干扰系统的大豆蚜虫的可行性。 大豆蚜是一种新的入侵性害虫，也是大豆上唯一的蚜虫害虫。该物种作为直接害虫或植物病毒的载体造成重大经济损失。该第一阶段项目将确定和优化大豆蚜的性信息素混合物，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干扰或通过大量诱捕来干扰雌性的交配。 廉价获得大量信息素成分的新方法也将开始。 这项研究建立在初步研究的基础上，初步研究表明，大豆蚜虫可以在实验室中在受控条件下培养，以产生性活跃的成虫。 初步实验表明，A.已知在其他蚜虫物种中作为信息素成分的两种化合物的甘氨酸。 这些化合物在风洞中引起雄性的逆风飞行，并且在田间对雄性和雌育的雌性大豆蚜虫都有吸引力。 预计针对大豆中的蚜虫物种开发的技术也可适用于其他重要经济作物中的其他蚜虫害虫。

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.
