Artificial overwintering, assuming that adulthood is the overwintering stage, has been performed on six experimental populations of Drosophila melanogaster. In five of them, the frequency of flies infected by the hereditary Rhabdovirus sigma is always in the first spring generation than it was in the last generation of the preceding fall. This result might indicate a higher sensitivity of infected flies to winter conditions, but other interpretations, connected with the genes for resistance to the virus might be considered. In one of the six populations, no effect was detected after any of the three successive winters. It appears therefore that the genetic background of the flies or/and of the propagated virus intervenes in the response to overwintering.
假定成虫期为越冬阶段，对六个黑腹果蝇实验种群进行了人工越冬处理。在其中五个种群中，感染遗传性西格玛弹状病毒的果蝇频率在次年春季第一代中总是高于前一年秋季最后一代。这一结果可能表明受感染果蝇对冬季条件更为敏感，但也可以考虑与抗病毒基因相关的其他解释。在六个种群中的一个种群里，连续三个冬季过后均未检测到任何影响。因此，果蝇或/和所传播病毒的遗传背景似乎会干预对越冬的反应。
