Feasting on the dead: the fitness consequences of infectious scavenging in Drosophila. Monteith, K., Borthwick, H., Vale, P., Monteith, K., Borthwick, H., & Vale, P.

Paper doi abstract bibtex In Drosophila (Diptera), scavenging on carcasses of conspecifics occurs during the larval stage. In many species this behaviour, detrivory, is a major factor in spreading horizontally transmitted diseases. Scavenging of infected carcasses can have significant consequences on individual fitness. Thus, scavenging avoidance of infected carcasses can be highly advantageous. We tested if Drosophila larvae show preference in consumption of infected and uninfected conspecific carcasses. Assess the fitness consequences in Drosophila of larval scavenging on infected carcasses and determine whether consequences vary with carcass sex. 72hr larvae show no preference in the consumption of DCV infected and uninfected adult carcasses.Consumption of infected carcasses resulted in a low level infection in larvae which continued into adulthood. Sex of the carcass consumed had no effect on infection status. Consumption of infected carcasses, and acquiring a low level infection, had no effect on developmental stages but resulted in a significantly shorter lifespan, however this effect was only apparent if larvae consumed infected male carcasses.
