Abstract

This study has been made for the seasonal occurrence of major insect pests which occurred in greenhouse-grown hydrangea and the selection of pesticide from March 2013 to December 2014. Major insect pests included Tea red spider mite (Tetranychus kanzawai Kishida), Garden thrips (Frankliniella intonsa), and Melon aphid (Aphis gossypii glover). And among them, insect pests requiring being controlled were T. kanzawai, and F. intonsa. With regard to seasonal occurrence, T. kanzawai occurred in mid-March, and showed the peak period of occurrence in early June, and then showed that it tended to rapidly decrease. F. intonsa started to occur from early April, and its peak period of occurrence was late-June. With regard to the selection of pesticide, in case of T. kanzawai, 4 types such as abamectin emulsifiable concentrate showed a high control value of 93% or above, and in case of F. intonsa, 2 types such as acetamiprid wettable powder too. No pesticides with which hydrangea was treated had phytotoxicity. On the other hand, with regard to the sticky trap
