摘　　要：通过对悬铃木方翅网蝽越冬与出蛰活动调查分析,结果表明,越冬代成虫主要集中在树干基部翘皮内,次年2月份越冬虫数明显低于12月份越冬虫数,当次年连续数日最低气温都在10℃以上时,越冬代成虫才能转移到悬铃木下层叶片。成虫通过24 h低温处理,-6℃、-7℃、-8℃、-9℃、-10℃下其平均死亡率分别为21.11%、34.44%、51.11%、78.89%、100.00%。Analyses on the wintering and reviving of Corythucha ciliata（Say） showed that overwintering adult mainly gathered in the bark at the base of the trunk.The number of overwintering adult in February of the following year was lower than that in December the same year.Overwintering adult moved to the foot of leaves when the lowest temperature was above 10℃ for several days in the next year.After treated by the low temperature for 24 h,the mortality rate for the adult at-6℃,-7℃,-8℃,-9℃,and-10℃ were 21.11%,34.44%,1.11%,8.89%,and 100.00% respectively.
