(2003): Bioactivity of carvacrol and thymol against Frankliniella occidentalis and Thrips tabaci
Journal of Applied Entomology, 127, 313-316

Abstract:
Two constituents of essential oils, carvacrol and thymol, were tested for their effects on the feeding activity, oviposition preference and oviposition rate of Frankliniella occidentalis and Thrips tabaci. Given a choice between treated and untreated leaf discs, F. occidentalis avoided ovipositing on leaf discs treated with 1 or 0.1% thymol. In no-choice experiments, 1 and 0.1% thymol and 1% carvacrol resulted in a reduced oviposition rate of F. occidentalis compared with the control. Both constituents caused a slight reduction of the feeding damage of F. occidentalis. 1 and 0.1% carvacrol had a pronounced deterrent effect on the oviposition site selection of T. tabaci . Both constituents served as anti-ovipositants for both thrips species, albeit F. occidentalis was more affected than T. tabaci.
