Abstract

Tomato spotted wilt virus (TSWV) has been a major problem for south Texas peanut producers since 1985. Tobacco thrips, Frankliniella fusca, and western flower thrips (WFT), are confirmed vectors and are involved with the primary and secondary spread of TSWV in south Texas peanut. Adults and immatures were collected from peanut blooms and terminals at flowering to identify the thrips contaminated with TSWV and predict if they secondarily spread TSWV. Thrips were assayed by a Double Antibody Sandwich-Enzyme Linked ImmunoSorbent Assay for TSWV. F. fusca were most abundant (67%) and comprised 75% of the adult thrips with TSWV. WFT comprised 20% and 13% were contaminated with TSWV. Only 2% of the thrips collected were confirmed TSWV positive.
