Studies on the diel sugar feeding periodicity of male and female Aedes aegypti were conducted under laboratory conditions and monitored in single cages using the polyphagometer device and examined every 2h. Males mosquitoes displayed two peaks in sugar feeding, a small morning peak at 06.00-08.00 h (16% of sugar feeding) and a significant evening peak at 16.00-18.00 h (40% of sugar feeding). A similar pattern was observed among females: a small early morning peak (18% of sugar feeding) and a significant peak in the evening 16.00-18.00 h (42% of sugar feeding). Studies on the effects of sugar feeding on the excitation of males showed 100% erect antennal fibrillae after 36 h. In contrast, only 15% of the water-fed males responded. Laboratory studies on the effects of sugar feeding on the insemination rates of A. aegypti females showed similar inseminations rates among sugar and water fed males but after 4 days all water fed males died while the sugar fed males continued to survive and inseminate females. The synchronization of the male and female diel sugar feeding periodicity is discussed in the context of sterile insect techniques or genetic control methods.
在实验室条件下，对雄性和雌性埃及伊蚊的昼夜糖食周期性进行了研究，并使用多相计在单个笼中进行监测，每 2 小时检查一次。雄性蚊子的糖食有两个高峰，早上 6 点到 8 点的小高峰（占糖食的 16%）和晚上 16 点到 18 点的显著高峰（占糖食的 40%）。雌性蚊子也表现出类似的模式：早上有一个小高峰（占糖食的 18%），晚上 16 点到 18 点有一个显著高峰（占糖食的 42%）。对糖食对雄性兴奋影响的研究表明，36 小时后 100%的雄性触角纤毛竖起。相比之下，只有 15%的水喂养雄性有反应。实验室研究表明，糖食对埃及伊蚊雌性的授精率没有影响，糖食和水喂养的雄性授精率相似，但 4 天后，所有水喂养的雄性都死亡，而糖喂养的雄性继续存活并授精雌性。还讨论了雄蚊和雌蚊昼夜糖食周期性同步的问题，这在不育昆虫技术或遗传控制方法的背景下是有意义的。
