Key Words: Soybean Aphid - Biocontrol, Soybean Aphid, Virus-inducted Gene Silencing
Aphids cost US agriculture billions of dollars/year in yield losses and costs of pesticide application used in aphid control. In recent years, the soybean aphid has been a serious problem for Iowa soybean producers, costing them millions of dollars in aphid control (pesticide application) and/or yield loss. Genetic resistance is inadequate and other effective management options are limiting. This project is to investigate the use of viruses and/or virus genes to kill or control the soybean aphid. This new approach may lead to new biological control and/or transgenic resistance tools to reduce or eliminate yield loss results from soybean aphid infestations. The researchers will: • Clone two aphid lethal paralysis viruses (ALPV and ALPLV) and propagate large quantities of these viruses in aphid cell lines for field studies; • Develop a virus-inducted gene silencing (VIGS) vector for silencing of aphid genes; and • Compare the biological properties of the two viruses (ALPV and ALPLV).
