豌豆蚜种群内的颜色变化影响对捕食者和寄生虫的相对易感性。我们已经发现，感染一种兼性内共生体的立克次氏体属改变昆虫的体色从红色到绿色在自然种群。在西欧收集的豌豆蚜虫中约有8%携带立克次氏体感染。感染增加了蓝绿色多环醌的数量，而它对黄红色类胡萝卜素色素的影响较小。内共生体对体色的影响预计会影响猎物-捕食者的相互作用，以及与其他内共生体的相互作用。
Color variation within populations of the pea aphid influences relative susceptibility to predators and parasites. We have discovered that infection with a facultative endosymbiont of the genus Rickettsiella changes the insects' body color from red to green in natural populations. Approximately 8% of pea aphids collected in Western Europe carried the Rickettsiella infection. The infection increased amounts of blue-green polycyclic quinones, whereas it had less of an effect on yellow-red carotenoid pigments. The effect of the endosymbiont on body color is expected to influence prey-predator interactions, as well as interactions with other endosymbionts.
