a Relative abundance of bacterial genera in 3-day and 6-day-old Ae. aegypti recipient adults that emerged from cultures inoculated with donor pools generated from either Ae. aegypti or Cx. quinquefasciatus individuals. Each bar represents an individual mosquito. Genera representing > 1% of reads from any one donor individual are listed in the legend; all other taxa are grouped together under “Other.” b and c Alpha and beta diversity of recipient Ae. aegypti adults emerging from cultures inoculated with pools generated from Ae. aegypti (Aa) or Cx. quinquefasciatus (Cq) donor individuals. Panel b shows the difference in alpha diversity between Aa and Cq recipient adults as measured by Shannon’s H index (left) and ASV richness (right). Box-and-whisker plots show high, low, and median values, with lower and upper edges of each box denoting first and third quartiles, respectively. Asterisks (***) indicate significant differences between Aa and Cq recipient adults (Kruskal-Wallis test, P < 0.05). Panel c shows the difference in beta diversity between Aa and Cq recipient adults. Principal coordinates analysis using the Bray-Curtis dissimilarity index identified significant clustering by donor species (PERMANOVA, P = 0.001)
