为了解张家界地区所产角倍蚜Schlechtendalia chinensis(Bell)秋迁蚜及越冬若蚜的耐寒性及两虫态间在耐寒性方面的差异,应用过冷却点测定仪,抽样测定了上述两虫态个体的过冷却点和体液结冰点,结果表明:秋迁角倍蚜过冷却点和体液结冰点的平均值、最低值和最高值分别依次为-13.32±0.77, -15.69, -11.12℃和-13.00±0.72, - 14.54, - 10.80℃;而无翅若蚜过冷却点和体液结冰点的平均值、最低值和最高值分别依次为-18.95±0.82, -20.24, - 17.02℃和-18.70 ±0.82, -20.07, -16. 95℃。方差分析表明,越冬若蚜的过冷却点和体液结冰点都明显低于秋迁蚜的过冷却点和体液结冰点,进而推测,越冬若蚜的耐寒...

The cold resistance, supercooling points and body fluid freezing points of two instars of Schlechtendalia chinensis （Bell） were determined using of a supercooling point tester. The average, minimum and maximum values of the supercooling and freezing points of the body fluids of autumn aphids were - 13.32± 0.77, - 15.69, - 11.12℃ and - 13.00± 0.72, - 14.54, - 10.80℃. Average, minimum and maximum values of supercooling and freezing points of the body fluids of wingless nymph-aphids of S. chinensis were - 18.95 ± 0. 82, -20.24, - 17.02℃ an...
