埃及伊蚊（Aedes aegypti（L.）鸡蛋从自然发生的容器，调查选择性产卵，未能考虑到某些方面的Ae。埃及人的行为会使研究推断产生偏差。在秘鲁的伊基托斯，我们测试了与设计Ae相关的三个假设。埃及伊蚊产卵的野外研究如下：1）用纸作为产卵基质的内衬容器不影响产卵; 2）日产卵活动在下午晚些时候或傍晚早些时候达到高峰，并且在中午期间几乎没有产卵;以及3）野生雌性的生殖营养周期长度平均为3至4天。当野生女性提出的容器内衬和内衬纸巾，纸的存在下，塑料和金属容器中的产卵增加，但在水泥容器中没有影响。记录Ae产下的蛋数量。埃及伊蚊在一天中每2小时产卵一次，其昼夜产卵模式为双峰型，上午产卵高峰较小，中午活动减少，下午晚些时候和晚上16：00至20：00为主要产卵高峰。对圈养个体F0雌性的日常监测显示，伊基托斯种群的性腺营养周期长度通常为3- 4 d。这些结果将用于调整田间研究设计，以1）说明使用纸巾对卵进行采样，2）确定对Ae进行采样的时间和天数。埃及卵我们探讨了如何不考虑这些行为可能会有偏见的产卵偏好领域的评估。
When devising methods to sample Aedes aegypti (L.) eggs from naturally-occurring containers to investigate selective oviposition, failure to take into account certain aspects of Ae. aegypti behavior can bias study inferences. In Iquitos, Peru, we tested three assumptions related to designing Ae. aegypti oviposition field studies, as follows: 1) lining containers with paper as an oviposition substrate does not affect oviposition; 2) diurnal egg-laying activity peaks in the late afternoon or early evening, and there is little oviposition during midday; and 3) the gonotrophic cycle length of wild females averages from 3 to 4 d. When wild females were presented with containers lined and unlined with paper toweling, the presence of paper increased oviposition in plastic and metal containers, but had no effect in cement containers. Recording the number of eggs laid by Ae. aegypti every 2 h throughout the day delineated a bimodal diurnal oviposition pattern, with a small morning peak, decreased activity during midday, and a predominant peak in the late afternoon and evening from 16:00 to 20:00 h. Daily monitoring of captive individual F0 females revealed that the gonotrophic cycle length was typically 3– 4 d for the Iquitos population. These findings will be used to adjust field study design to 1) account for sampling eggs using paper toweling, and 2) determine the time of day and number of days over which to sample Ae. aegypti eggs. We explored how failure to consider these behaviors could potentially bias field assessments of oviposition preferences.
