摘　　要：测定了悬铃木方翅网蝽Corythucha ciliata(Say)2个地理种群(湖北荆州种群和河南郑州种群)的过冷却点,结果表明,荆州种群1日龄和5日龄成虫的过冷却点分别为-16.519℃和-21.646℃,而郑州种群1日龄和5日龄成虫的过冷却点为-17.329℃和-21.617℃。2个地理种群的过冷却点没有明显差异,但同一地理种群1日龄和5日龄成虫间的过冷却点差异显著。The supercooling points （SCPs） of two geographical populations （Jingzhou, Hubei Province; Zhengzhou, Henan Province） of Corythucha ciliata （Say） was experimentally tested. The results showed that the SCPs of 1-day adults and 5-day adults were - 16.519 ℃ and - 21.646 % , respectively, in Jingzhou population, and - 17.329 ℃ and - 21.617 ℃, respectively, in Zhengzhou population. The SCPs between two geographical populations had no significant difference, but in same geographical population, the SCPs between 1-day adult and 5-day adults had significant difference.
