16S microbiota diversity. A Brays-Curtis multidimensional scaling plot showing MDS1 (x-axis) and MDS2 (y-axis) for the calculated abundances. Each point represents one pool of five individuals; the colour represents alive (green) and dead (pink) after deltamethrin exposure, and unexposed controls (yellow). The shape indicates species Anopheles arabiensis (circle), An. gambiae (diamond) and An. coluzzii (square). The shape outline denotes the country: Burkina Faso (black), Ethiopia (turquoise), Germany (pink) and the UK (green). Ellipses represent each country cluster and are labelled as such. B Relative abundance (% y axis) plots for each pool of five individuals (x axis) at genus level. Label acronyms are as follows: col = An. coluzzii. Alive samples are denoted by a blue bar, control a yellow bar and dead a pink bar immediately below the x-axis. Countries are denoted by a bar and coloured as in A
