表型可塑性是指表型的环境控制。在发育过程中（发育可塑性）或成年期（适应性）经历的线索都可以影响成年人的表型。表型可塑性已被描述在许多性状，但发育可塑性的例子，特别是在生理性状，仍然很少。我们研究了发育可塑性和适应性的信息素生产的蝴蝶Bicyclus anynana在饲养温度。B。Anynana生活在非洲热带地区，潮湿季节温暖的养育温度产生了活跃的求偶雄性和选择的雌性，而干燥季节的凉爽温度导致了挑剔的不太活跃的雄性和求偶雌性。我们假设，如果雄性信息素的生产是昂贵的，它应该减少在旱季的形式。在描述了信息素产生细胞的超微结构后，我们发现，旱季男性产生的性信息素显着低于雨季男性，部分原因是由于驯化，部分原因是由于发育可塑性。其中一种化合物水平的变化与信息素生物合成酶基因的差异调节有关。这种可塑性可能是一种适应，以尽量减少信息素生产成本在紧张的旱季。
Phenotypic plasticity refers to the environmental control of phenotypes. Cues experienced during development (developmental plasticity) or during adulthood (acclimatization) can both affect adult phenotypes. Phenotypic plasticity has been described in many traits but examples of developmental plasticity in physiological traits, in particular, remain scarce. We examined developmental plasticity and acclimatization in pheromone production in the butterfly Bicyclus anynana in response to rearing temperature. B. anynana lives in the African tropics where warm rearing temperatures of the wet season produce active males that court and females that choose, whereas cooler temperatures of the dry season lead to choosy less active males and courting females. We hypothesized that if male pheromone production is costly, it should be reduced in the dry season form. After describing the ultrastructure of pheromone producing cells, we showed that dry season males produced significantly less sex pheromones than wet season males, partly due to acclimatization and partly due to developmental plasticity. Variation in levels of one of the compounds is associated with differential regulation of a pheromone biosynthetic enzyme gene. This plasticity might be an adaptation to minimize pheromone production costs during the stressful dry season.
