Interpretive Summary:

Technical Abstract: Impatiens necrotic spot virus (INSV) has been a major problem for lettuce produced in the Salinas Valley of California and has raised concern that it may establish in desert regions. INSV is transmitted by the western flower thrips, Frankliniella occidentalis, a small and ubiquitous insect. The presentation will provide an update on research that has been conducted to assist in the management of thrips and INSV. Topics will cover 1) regional monitoring of thrips populations in the Salinas Valley, 2) field surveys to identify abundance and distribution of thrips among various crops and weedy species, 3) INSV susceptibility testing of cover crops, and 4) studies to understand the timing of INSV and Pythium uncinulatum co-infections. The meeting and presentation are relevant for stakeholders involved in vegetable production in desert regions, including Imperial County.
