Egg laying behavior in Aedes triseriatus was studied in an oak woodlot endemic for La Crosse encephalitis virus in southwestern Wisconsin. Daily counts from oviposition traps allowed the calculation of spatial distribution parameters for eggs during 1988. Egg distribution along an ellipsoidal transect of 25 traps was clumped with some traps being more attractive to ovipositing female Ae. triseriatus than others. Females were estimated to deposit a mean of 31 +/- 9.8 eggs per oviposition.
在威斯康星州西南部一片存在拉克罗斯脑炎病毒的橡树林中，对三带喙库蚊的产卵行为进行了研究。通过对诱卵器的每日计数，得以计算出1988年期间蚊卵的空间分布参数。沿着由25个诱卵器组成的椭圆形样带，蚊卵分布呈聚集状态，有些诱卵器比其他诱卵器对正在产卵的三带喙库蚊雌蚊更具吸引力。据估计，雌蚊每次产卵平均为31±9.8枚。
