奈良県の露地キクから採集したミカンキイロアザミウマに対する各種殺虫剤の殺虫効果

抄録

For two western flower thrips (WFT) populations collected from chrysanthemum fields in Nara prefecture, toxicities of seven insecticides were investigated. Fipronil was most effective in terms of corrected mortality, followed by prothiofos and chlorfenapyr. Tolfenpyrad, thiocyclam and abamectin were less effective in terms of corrected mortality but leaf damages were scarce. Spinosad was less effective in terms of corrected mortality and leaf damage. These result suggest that WFT populations on chrysanthemum in Nara prefecture developed resistance to spinosad.
