Interpretive Summary:

Technical Abstract: Western flower thrips (Frankliniella occidentalis) is the primary insect vector for Impatiens necrotic spot virus (INSV), a prevalent disease affecting lettuce production in the Salinas Valley. Since first reported in 2008, research and monitoring of INSV in the Salinas Valley has been limited, despite reports of increasing thrips populations and INSV outbreaks in recent years. This seminar will review the current research currently being conducted on thrips and INSV in the Salinas Valley. Topics include: 1) timing of thrips infestations and INSV symptom development in commercial lettuce fields, 2) understanding the impact of secondary host plant reservoirs for INSV and their impact on commercial lettuce production, and 3) improving trapping methods to identify the proportion of thrips within a population that are vectoring INSV using molecular tools.
