The diel oviposition periodicities of the LSHTM and Trinidad strains of Aedes aegypti were studied under laboratory conditions, using different mosquito densities in the cages and monitoring at 2-h intervals. With both strains, the peak in oviposition occurred earlier in the day when there was only one female in a test cage (16.00-18.00 hours) than when 25 or 500 females were held in a cage (18.00-20.00 hours). It therefore appears that the numbers of females in the cages can affect the diel oviposition periodicity of Ae. aegypti in the laboratory and that, therefore, caution is necessary when using and comparing data from related laboratory studies in which the ovipositing mosquitoes have been held at various densities.
在实验室条件下，研究了伦敦卫生与热带医学院（LSHTM）株和特立尼达株埃及伊蚊的昼夜产卵周期，在笼子里设置不同的蚊子密度，并每隔2小时进行监测。对于这两个品系，当测试笼中只有一只雌蚊时（16:00 - 18:00），产卵高峰期出现在当天较早的时候，而当一个笼子里有25只或500只雌蚊时（18:00 - 20:00），产卵高峰期出现得较晚。因此，似乎笼子里雌蚊的数量会影响实验室中埃及伊蚊的昼夜产卵周期，所以在使用和比较相关实验室研究的数据时需要谨慎，这些研究中产卵的蚊子被饲养在不同的密度下。
