Ovitraps were set inside and outside of 15 households in December 2012 (dry season) and August 2013 (rainy season) in 2 communes (An Thanh and Phu Hoa) of Binh Duong Province in southern Vietnam. Eggs laid in the ovitraps were collected after 4 days, dried, and soaked in water. Hatched larvae were transferred to cups and reared to adulthood to identify the species. The rate of positive ovitraps did not differ between December and August for Aedes aegypti, but it was lower in December for Ae. albopictus. The number of eggs laid per ovitrap by Ae. aegypti did not differ between December and August, while that for Ae. albopictus decreased significantly in December in both communes. Moreover, Ae. albopictus laid eggs in ovitraps placed outside the households. Therefore, it is necessary for future studies to investigate whether the major source containers for oviposition had dried in the dry season or Ae. albopictus entered diapause, leading to these observations.
2012 年 12 月（旱季）和 2013 年 8 月（雨季），在越南南部的平福省安富和福华两个公社，在 15 户家庭内外设置诱卵器。诱卵器中的卵在 4 天后收集、干燥并浸泡在水中。孵化的幼虫被转移到杯子中饲养至成年，以确定物种。埃及伊蚊的诱卵器阳性率在 12 月和 8 月之间没有差异，但白纹伊蚊的阳性率在 12 月较低。埃及伊蚊在 12 月和 8 月的每个诱卵器中产卵的数量没有差异，而在两个公社，白纹伊蚊的产卵数量在 12 月显著减少。此外，白纹伊蚊在家庭外的诱卵器中产卵。因此，未来的研究有必要调查在旱季，主要的产卵容器是否已经干涸，或者白纹伊蚊是否进入滞育期，导致了这些观察结果。
