According to the results published in the journal Proceedings of the Royal Society B, both male and female fruit flies
Establishing an immune response isenergetically "expensive", so infections are thought to reduce the amount of energy available for mating. However, the new study found that infected fruit flies continued to court and mate regardless of whether males or females were infected.
Dr. Carolina Rezaval, Headresearch group at the University of Birmingham, explains: “Animals have limited energy resources that need to be allocated between different activities, such as fighting infection or mating. We were interested in understanding how animals prioritize immune defense and reproduction."
Scientists studied the fruit fly Drosophila.By infecting both males and females with a variety of pathogens, varying in type and severity, the scientists made a surprising discovery. It turned out that courtship and mating behavior were the same in both infected and uninfected flies. Moreover, uninfected flies mated equally often with both infected and healthy partners.
However, previous studies have shown thatinfected flies may exhibit abnormal body movements, sleep, and feeding behavior. Consequently, the new work suggests that courtship and mating are prioritized among individuals. For them, this is more important than not getting infected and surviving. However, scientists note that more research is needed. The goal is to understand what happens in the brain to maintain reproductive behavior in the face of infection.
