The epidemiological model was parameterized by sampling frequency distributions of experimental data collected from 10 Drosophila Genetic Reference Panel lines for both male and female flies infected with DCV published previously [13,17]. Here, we provide a qualitative description of these data. (a) Social aggregation: the average number of neighbouring flies present within a 15 mm radius of each focal fly; (b) infectiousness: the number of viral copies shed per fly within the first 3 days following infected, as measured by DCV-specific qPCR; (c) the day of death of each individual infected fly. Detailed analysis showing extensive line-by-sex interactive effects are reported in [13,17]. (Online version in colour.)
