The diel oviposition periodicity of two groups of Aedes aegypti females (Trinidad strain), (i) thoses allowed access to oviposition sites and (ii) females forced to retain-eggs for four days, were studied under laboratory conditions using one female per cage and monitoring by changing substrates every two hours. The individual females which were allowed access to oviposition sites showed peak oviposition between 16.00-18.00 h (50% of eggs), whereas individuals forced to retain eggs for four days showed a similar pattern but with a significantly (P<0.001) larger peak oviposition between 16.00-18.00 h (94% of eggs). However, females forced to retain eggs laid most or all of their eggs in one container (84%), while females given access to oviposition sites distributed their eggs among 2-4 containers. The results of this study are discussed in the context of the strength of the circadian rhythms, oviposition strategies and its impact on vector control activities.
在实验室条件下，对两组埃及伊蚊雌性（特立尼达菌株）的昼夜产卵周期性进行了研究，一组（i）可进入产卵场所，另一组（ii）被迫保留卵四天，每个笼子放一只雌性，并每两小时更换底物进行监测。可进入产卵场所的个体雌性在16:00 - 18:00时出现产卵高峰（占卵的50%），而被迫保留卵四天的个体呈现类似模式，但在16:00 - 18:00时产卵高峰显著更大（占卵的94%，P<0.001）。然而，被迫保留卵的雌性将大部分或所有卵产在一个容器中（84%），而可进入产卵场所的雌性则将卵分布在2 - 4个容器中。本研究结果在昼夜节律强度、产卵策略及其对病媒控制活动的影响背景下进行了讨论。
