摘要
研究了采自越南胡志明市和我国海南省、北京市和新疆石河子市棉蚜在不同温度下发育体型和体色的变化。结果表明,不同气候带的棉蚜的体型和体色特征存在分化。海南棉蚜种群与北京种群和新疆种群在头宽、前足腿节、前足胫节、中足腿节、中足胫节、后足腿节、后足胫节和腹管长方面均存在显著差异。成蚜和幼蚜体型随温度降低明显增大。越南、海南和北京种群在低温下(15℃)发育的成蚜体型随纬度升高而明显增大。
Morphological variation of cotton aphid, Aphis gossypii Glover, collected from Vietnam, Hainan Province, Beijing and Xinjiang Autonomous Region of China were studied in laboratory. The results indicated that there were significant differences in morphology and color under various temperatures. In particularly, head width, foreleg femur, foreleg tibia, midleg femur, midleg tibia, hindleg femur, hindleg tibia and cornicles in Hainan population showed significant differences with those of Beijing population and Xinjiang population. The size of both adult and larv aphids gradually increased with decreased temperature in general. It was found that as the latitude of location of the aphid increased, size of the adult of the populations from Vietnam, Hainan and Beijing of China developed at 15℃ presented a increasing trend .
