Flies infected or uninfected by the hereditary Rhabdovirus sigma have been collected in the natural French populations of Drosophila melanogaster. The have been compared for various physiological traits: male and female fertility, female longevity, sexual selection and egg viability. The only significant difference was the lower viability of eggs laid by infected females. For all the other traits, infected and uninfected flies were quite comparable. The viral types found in flies of wild origin, thus appear to be almost harmless for their carriers. This result can be connected with previous findings which gave evidence for the relative infrequency of infectious particles in stabilized flies of wild origin.
在法国果蝇自然种群中收集了感染或未感染遗传性西格玛弹状病毒的果蝇。对它们的各种生理特征进行了比较：雌雄生育力、雌蝇寿命、性选择和卵的活力。唯一显著的差异是受感染雌蝇所产卵的活力较低。对于所有其他特征，受感染和未感染的果蝇相当可比。因此，在野生果蝇中发现的病毒类型对其携带者似乎几乎无害。这一结果可以与之前的研究结果联系起来，之前的研究结果证明在野生稳定果蝇中感染性颗粒相对罕见。
