Females of the sunflower moth, Homoeosoma electellum held in the presence of pollen, or an ethanolic pollen extract, from the sunflower Helianthus annuus initiated calling behavior at a significantly younger age following emergence than those provided sucrose only. Furthermore, females with pollen subsequently spent more time calling, and had an increased rate of egg maturation, than those held without pollen. These effects were attributed to a kairomone as females held in the presence of, but denied direct access to, pollen behaved in the same manner as those in contact with pollen. The importance of this life history strategy for the exploitation of temporarily available resources, essential to the survival of neonate larvae, and on the dispersal of adults, is discussed.
在有来自向日葵（Helianthus annuus）的花粉或乙醇花粉提取物存在的情况下饲养的向日葵螟（Homoeosoma electellum）雌蛾，羽化后开始求偶行为的年龄比仅提供蔗糖的雌蛾显著更小。此外，接触花粉的雌蛾随后求偶的时间更长，且卵成熟率更高。这些效应归因于一种利它素，因为在有花粉存在但无法直接接触花粉的情况下饲养的雌蛾，其行为方式与接触花粉的雌蛾相同。本文讨论了这种生活史策略对于利用暂时可得资源（这对新生幼虫的生存至关重要）以及成虫扩散的重要性。
