摘    要:为探索棉蚜Aphis gossypii Glover种群动态与高温的关系,研究了不同温度(30、34、38、42、46℃)、不同处理时间(1、2、5、8h)对棉蚜存活的影响。结果表明:在同一处理时间条件下,棉蚜的存活率随着温度的升高而降低;在同一处理温度下,棉蚜的存活率随处理时间的延长而降低。30~38℃温度范围内,棉蚜存活率降低缓慢,从42℃开始棉蚜的存活率迅速降低。棉蚜半数致死温度随着处理时间的延长而降低;相同处理时间条件下,若蚜半数致死温度高于成蚜,若蚜较成蚜更耐高温。

关 键 词:棉蚜  高温  存活率  半数致死温度

Abstract:Detailed experiments were conducted to assess the effects of high temperatures (30,34,38,42 and 46℃ ) and the length of exposure to these (1,2,5 and 8 h) on the survival of Aphis gossypii Glover. The results show that survival decreased with increasing temperature and duration of exposure. The survival of A. gossypii decreased slowly between 30℃ and 38℃ ,but rapidly at 42℃ and above. The LT50 of aphids decreased with increasing exposure to high temperatures. Adult aphids had lower tolerance to high temperatures than nymphs.
Keywords:Aphis gossypii  high temperature  survival  LT50
