Frankliniella intonsa (Trybom) (Thysanoptera: Thripidae) is an important pest in protected culture. We assessed fourrepellents (carvacrol, cis-jasmone, methyl jasmonate, and methyl salicylate) of Frankliniella occidentalis (Pergande)(Thysanoptera: Thripidae) known from literatures to develop a behavioral management tactic against F. intonsa. We measuredthe repellency of F. intonsa that exposed to 100 times diluted repellents on leaf disc. Repellency was 2.60 times higherin methyl jasmonate followed by methyl salicylate (2.16 times), cis-jasmone (2.15 times) and carvacrol (2.08 times) comparedto control. These results suggest that methyl jasmonate can be incorporated as a component of integrated managementof F. intonsa.
