Oocyst prevalence and Plasmodium vivax infection density in An. culicifacies species A and species B.

Mosquito mid-guts were examined for P. vivax live oocysts 9–14 days post infection. Oocyst prevalence is the percentage of mosquitoes displaying at least one live oocyst, and Oocyst density is the median number of oocysts in infected mosquitoes infection of An. culicifacies species B was not observed in experiment 1. The oocyst prevalence was analyzed with the chi-square Fishers exact test with Yates correction, and the oocyst density with the Kruskal –Wallis non-parametric ANOVA. n: number of mosquitoes, ns: not significant.
