The oviposition behaviors of Orthopodomyia signifera and Aedes sierrensis were examined with ovitraps and larval surveys during a five-year field study in northern California. Ovipositional periodicity was found to be an important factor affecting the segregation of the species into tree holes that were temporarily (Ae. sierrensis only) or permanently (both species) filled with water. Orthopodomyia signifera females also used cues associated with the permanence of the habitat when selecting oviposition sites. The distributions of the eggs of each species along horizontal and vertical transects did not indicate that interspecific competition affected oviposition site selection. The data indicate that temporal partitioning of larval development may reduce interspecific competition. Ovitraps were determined to be more sensitive tools for surveillance of Or. signifera than larval surveys, CO2-baited Fay traps and CDC light traps.
在加利福尼亚北部进行的一项为期五年的野外研究中，使用诱蚊产卵器和幼虫调查对标志正角蚊和内华达伊蚊的产卵行为进行了研究。发现产卵周期是影响这两个物种在临时（仅内华达伊蚊）或永久（两个物种都有）积水树洞中的分布隔离的一个重要因素。标志正角蚊雌蚊在选择产卵地点时也会利用与栖息地永久性相关的线索。每个物种的卵沿水平和垂直样带的分布并未表明种间竞争影响产卵地点的选择。数据表明，幼虫发育的时间划分可能会减少种间竞争。诱蚊产卵器被确定为比幼虫调查、二氧化碳诱饵费氏诱蚊器和疾控中心灯光诱捕器更灵敏的监测标志正角蚊的工具。
