Fig. 6: DL-MIRS validation on wild mosquito populations.
From: Rapid age-grading and species identification of natural mosquitoes for malaria surveillance
The proportion of wild female mosquitoes with 0, 1 or ≥2 gonotrophic cycles (G0, G1, G2+G3+G4) was determined by ovarian dissection and morphological characterisation (yellow) or predicted by DL-MIRS on non-dissected mosquitoes (blue). The same number of mosquitoes for each group was analysed on each day of collection, either from Burkina Faso (a, An. coluzzii) or from Tanzania (b, An. arabiensis). The mean proportions and 95% credible intervals of the age proportion from dissected mosquitoes (yellow) were estimated with a Dirichlet distribution. The age proportion predicted by the DL-MIRS (blue) is presented as box-whisker plots showing the median, interquartile range (IQR, box), lowest/highest data within 1.5 IQR (whiskers), and outliers (red points) of the probability distribution of predictions from ten different models.
