Interspecific associations between two mosquito species can lead to effects such as competition, species displacement, and species stability. To better understand Aedes albopictus (Skuse) and other Aedes species, we monitored eggs in artificial oviposition cups (ovitraps) within Knox County, TN, U.S.A., during the 2016 and 2017 mosquito seasons. In 2016, one black and one white ovitrap were placed at 18 sites for 21 weeks, while in 2017 black and white ovitraps baited with grass-infused or deionized water were placed at 11 sites for nine weeks. Eggs were identified to species and resulting counts were used to determine the degree of interspecific association using Cole's coefficients (C ) and the degree of heterogeneity across space and time using generalized linear mixed models (GLMM). Here, Aedes mosquitoes are generally ovipositing in black cups with grass-infused water, and Ae. albopictus eggs co-occurred with other Aedes species more often than would be expected. Finding a positive significant interspecific association between Ae. albopictus and other Aedes eggs suggests that methods used to control Ae. albopictus may also control other Aedes mosquitoes. Finding that Ae. albopictus co-occurs with other Aedes mosquitoes warrants additional research to evaluate outcomes associated with co-occurrence within the study area.
两种蚊子之间的种间关联会导致竞争、物种替代和物种稳定等效应。为了更好地了解白纹伊蚊（Skuse）和其他伊蚊属物种，我们在美国田纳西州诺克斯县（Knox County）的 2016 年和 2017 年蚊子季节期间，在人工产卵杯（诱卵器）中监测了卵。在 2016 年，有 18 个地点各放置了一个黑色和一个白色的诱卵器，持续了 21 周，而在 2017 年，有 11 个地点各放置了黑色和白色的诱卵器，诱饵是注入草的水或去离子水，持续了 9 周。卵被鉴定为种，计数结果用于使用 Cole 系数（C）确定种间关联的程度，以及使用广义线性混合模型（GLMM）确定空间和时间上的异质性程度。在这里，伊蚊通常在黑色的、注入草的水的杯子中产卵，并且白纹伊蚊的卵与其他伊蚊属物种的共存比预期的更频繁。发现白纹伊蚊与其他伊蚊卵之间存在显著的正种间关联，这表明用于控制白纹伊蚊的方法也可能控制其他伊蚊属蚊子。发现白纹伊蚊与其他伊蚊共同存在，需要进一步研究，以评估在研究区域内共同存在所带来的结果。
