Abstract：In this study,the number of Apolygus lucorum was investigated during the occurrence period in tea garden,chrysanthemum garden and chrysanthemum-tea intercropping garden in Taishan area,and the control effects of different insecticides were compared during the autumn migration period of A.lucorum in tea garden,hoping to provide reference for the prevention and control of A.lucorum in Taishan tea area.The re-sults showed that September to November and April to June were the main occurrence periods of A.lucorum in tea gardens.The adults mainly occurred in mid-September to late October and mid-May to early June.Through monitoring the occurrence dynamic of A.lucorum in three planting patterns in autumn,it was found that the full-bloom chrysanthemum in September had a significant attraction effect on A.lucorum,and had an impact on the migration of A.lucorum in the near tea gardens.In October,after the chrysanthemum withered,the at-traction of flowering tea plants to A.lucorum began to highlight,so the number of A.lucorum in the chrysan-themum garden decreased rapidly,and the A.lucorum in the chrysanthemum-tea intercropping garden trans-ferred from chrysanthemum to tea plants to continue to harm.The results of different insecticides in the same period showed that the control effect of bifenthrin on A.lucorum in the tea garden was significantly superior to that of the other three insecticides,which was up to more than 80％at seven days after the third time applica-tion,so it could be used as the first choice in the control of A.lucorum in the tea garden.In addition,weeds around the tea garden could help A.lucorum hide and feed,so the weeds in the autumn tea garden should be included in the scope of prevention and control to improve the autumn control efficiency of A.lucorum in the tea garden.
