Oviposition preferences and rates of the pierid butterfly Colias eurytheme were examined in laboratory tests. Oviposition rates with only a non-preferred host plant present were not lower than rates observed when both preferred and non-preferred hosts were present. There was no correlation between strength of preference in simultaneous choice tests and the extent to which oviposition rate declined when the preferred host was absent. The results are consistent with the hypothesis that butterflies which lay their eggs singly will accept non-preferred hosts for oviposition more readily than cluster egg-layers.
在实验室测试中，对粉蝶科蝴蝶宽边云粉蝶的产卵偏好和产卵率进行了研究。仅存在非偏好寄主植物时的产卵率并不低于同时存在偏好寄主和非偏好寄主时观察到的产卵率。在同时选择测试中，偏好强度与偏好寄主不存在时产卵率下降的程度之间没有相关性。这些结果与以下假设一致：单独产卵的蝴蝶比成簇产卵的蝴蝶更愿意接受非偏好寄主进行产卵。
