This study was conducted to monitoring the insecticidal susceptibility of Western flower thrips, Frankliniella occidentalis, occurring the horticultural crops in Gyeonggi area. Bioassay was conducted under laboratory and greenhouse conditions using commercial insecticides being used for the control of thrips at their recommended concentrations. Neonicotinoid insecticides, especially acetamiprid SP, clothianidin SC, imidacloprid WP and thiacloprid WG were not toxic to F. occidentalis collected from horticultural crops. However, F. occidentalis collected vegetable greenhouse was very susceptible to the acetamiprid + spinetoram SC, clothianidin + spinetoram SC and methoxyfenozide + spinetoram SC which showed the control value over 90%. In greenhouse test, spinetram (5%) WG that had showed 100% of mortality to F. occidentalis in laboratory test also showed 87.4, 88.0, 98.3% of control values on 3, 6 and 9 days after treatment, while imidacloprid (10%) WP showed below 44% of control value. Excepting the insecticide of spinosin or pyrrole class, there was a little class of insecticides for the effective control of F. occidentalis in horticultural crop areas. Considering all the results in this study, spinosin insecticides including over 4 and 10% of spinetoram and spinosad, and pyrrole insecticide including over 5% of chlorfenapyr should be recommended for the effective control of F. occidentalis, damaging the horticultural crops in Gyeonggi area.
