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.
