球果角胫象系首次在云南发现,它为害云南油杉的球果。球果受害率为60～90％,其中有球果角胫象的球果占30～71％。球果角胫象占害虫总数的40％左右。该虫在昆明温泉地区一年发生一代,以成虫在受害果内越冬。越冬成虫于5月上旬开始活动,6月中、下旬开始出现幼虫,7～8月为幼虫取食为害的高峰期。8月上旬开始化蛹,8月下旬成虫开始羽化,成虫羽化后留在球果内越冬。建议采用建立云南油杉种子园和母树林、保护天敌及采摘受害果集中处理等方法来防治该虫。 Cone horn tibia was found in Yunnan for the first time, it is the damage of Yunnan oleander cones. Cone damage rate of 60 to 90%, of which the coniferous angle of the tibia like cones accounted for 30 to 71%. Cone horns as the total number of pests about 40%. The insects occurred in Kunming Hot Spring area a generation a year, with adult worms wintering in the fruit. Overwintering adults started their activities in early May, and larvae started to emerge in mid-June and late-July. The peak larvae fed on July-August. In early August pupation began, adults in late August began to emerge, adult feathers remain in the cones wintering. It is suggested that the pest should be controlled by establishing the seed orchard of Yacon ornithoratifica, the protection of natural enemies and the centralized treatment of harvested fruits.
