For different research purposes, there is a need to mass rear mosquitoes, such as Aedes aegypti, under laboratory conditions. The rearing process begins with egg production followed by egg storage in a dry environment, inside containers. Stored eggs are susceptible to environmental threats when storage conditions are suboptimal. Some terrestrial insects can invade this environment and attack stored eggs. In this brief report, we assessed whether Ae. aegypti eggs exposed to Liposcelis sp. individuals had reduced hatching and immature development rates. We exposed 100 eggs in different treatment conditions (fixed in porous paper and loosed) to 30 Liposcelis sp. individuals for ten days and then we induced hatching. We observed a hatching rate of 99% reduced for those eggs adhered to porous paper and loosed eggs showed a hatching rate of 45% decreased for those eggs exposed to Liposcelis sp. The remaining larvae took longer to develop into pupae as well, showing a four-day delay on average to the final metamorphosis of the aquatic stage. These results reinforce the need to frequently monitor egg storage conditions to maintain laboratory colonies stable and free from pests that can interfere with mosquito life-history traits.

出于不同的研究目的，需要在实验室条件下大规模饲养蚊子，例如埃及伊蚊。饲养过程从产蛋开始，然后是将蛋储存在干燥环境中的容器内。当储存条件欠佳时，储存的鸡蛋很容易受到环境威胁。一些陆生昆虫可以侵入这个环境并攻击储存的卵。在这份简短的报告中，我们评估了Ae. 暴露于Liposcelis sp. 的埃及卵 个体的孵化率和未成熟发育率降低。我们将不同处理条件下的 100 个鸡蛋（固定在多孔纸中并松开）暴露于 30 Liposcelissp. 个体十天，然后我们诱导孵化。我们观察到，粘附在多孔纸上的鸡蛋的孵化率降低了 99%，而暴露于Liposcelis sp 的鸡蛋的孵化率降低了 45% 。剩余的幼虫发育成蛹也需要更长的时间，平均延迟四天到水生阶段的最终变态。这些结果加强了经常监测卵子储存条件的需要，以保持实验室菌落稳定并且没有可能干扰蚊子生活史特征的害虫。
