1.在埃及伊蚊触角顶端的腔锥感器中发现了一对温度感受器单位。2.其中一个温度感受器对温度敏感，对温度的突然升高能产生相位紧张性的峰频率增加。第二个温度感受器是冷敏感的，对温度的突然降低以相态紧张性增加的峰电位活动作出反应。3.冷感受器和温感受器的平均紧张性峰电位活动都随着温度的升高而增加，冷感受器在26 ℃时达到峰值30 imp/sec，温感受器在28.5 ℃时达到峰值35 imp/sec。随着温度的进一步升高，紧张性活动下降。最大相位灵敏度观察到小的温度变化（δ T= ± 0.2 ℃）。在冷感受器中，温度下降136 imp/sec/℃，在暖感受器中，温度上升130 imp/ sec/℃。4.讨论了温度在蚊子寻找寄主和“攻击”行为中的重要性。
1.A pair of thermoreceptor units was identified in the sensilla coeloconica at the tip of the antennae on the mosquito,Aedes aegypti.2.One thermoreceptor was warm-sensitive and responded with a phasic-tonic increase in spike frequency to sudden increases in temperature. The second thermoreceptor was coldsensitive, responding with a phasic-tonic increase in spike activity to sudden decreases in temperature.3.The mean tonic spike activity of both the cold and warm receptors increased with increasing temperature to a peak of 30 imp/sec at 26‡ C for the cold receptor and 35 imp/sec at 28.5‡ C for the warm receptor. The tonic activity declined as the temperature was increased further. The maximum phasic sensitivity was observed with small temperature changes (δ T= ± 0.2‡C). This was 136 imp/sec/‡C temperature drop in the cold receptor and 130 imp/ sec/‡ C rise in the warm receptor.4.The importance of temperature in the host-seeking and “attack” behavior of the mosquito is discussed.
