摘要
测定了浙江乐清 (北纬 2 8 1 4°,东经 1 2 0 94°)稻水象甲LissorhoptrusoryzophilusKuschel越冬成虫的耐寒力 ,从 1 1月下旬至 3月下旬平均过冷却点温度为 -1 5 3～ -2 1 2℃ ,结冰点温度为 -1 4 0～ -1 8 6℃。结合发生地气温条件 ,讨论了该地冬春季低温对该虫越冬群存活的影响。
Cold hardiness of overwintering adults of the rice water weevil, Lissorhoptrus oryzophilus Kuschel, were investigated in a population collected from Yueqing (28\^14°N,120\^94°E), Zhejiang, China.During late November (early winter) and late March (mid\|spring), the mean supercooling point and freezing points of the adults ranged from -15\^3℃ to -21\^2℃ and from -14\^0 to 18\^6 ℃, respectively. Potential effects of low temperatures during winter and spring on survival of overwintering adults were evaluated based upon the historical records of local air temperature.
