摘要
为了解菊方翅网蝽的抗寒性和适生区域,对菊方翅网蝽[Corythucha marmorata(Uhler,1878)]越冬种群雌、雄成虫的过冷却点和冰点进行了测定。结果表明,雌成虫过冷却点为-10.97℃,冰点为-9.53℃;雄成虫过冷却点为-8.64℃,冰点为-7.40℃。雌成虫的过冷却点、冰点显著低于雄成虫。
In order to understand the cold hardiness and the suitable region of Corythucha marmorata(Uhler,1878)in China,the supercooling points(SCP)and freezing points(FP)of female and male Corythucha marmorata(Uhler,1878)adults were determined.The results showed that the SCP and FP of overwintering female adults were-10.97℃and-9.53℃respectively,and the SCP and FP of overwintering male adults were-8.64℃and-7.40℃respectively.The SCP and FP of overwintering female adults were significantly lower than male adults.
