Technical Abstract: Tospoviruses (genus: Tospovirus, family: Bunyaviridae) are a group of thrips-borne plant viruses that are emerging as a serious threat to many crops in global agriculture and horticulture. It has been estimated that tospoviruses cause global yield losses of about $US 1 billion in a wide range of crops. Worldwide, at least sixteen different tospoviruses are reported as pathogens on vegetables and other crops and at least twelve species of thrips (Thysanoptera:Thripidae) have been confirmed as vectors of one or more tospoviruses. In recent years, diseases caused by tospoviruses have increasingly become a significant limiting factor in the sustainable production of vegetables in smallholder farming systems of South and Southeast Asia (S & SEA) region. Because registered insecticides give poor control of thrips and the virus can be transmitted with only a few minutes of thrips feeding, efforts to control diseases caused by tospoviruses through insecticides have been mostly unsuccessful. The Integrated Pest Management-Collaborative Research and Support Program (IPM-CRSP) of USAID has recently funded a multi-disciplinary and multi-institutional project to conduct strategic research on tospoviruses and vector thrips, develop robust and high throughput diagnostic tools for accurate detection of tospoviruses in plants, and strengthen institutional capacity in developing countries through training programs and technology dissemination activities. It is envisioned that the project outputs will strengthen the capacity of developing countries in S & SEA to deploy environmentally benign integrated disease management strategies for mitigating losses caused by tospoviruses.
