Results from analysis of variance of (a) viral RNA concentration in the bodies (thorax+abdomen) of infected mosquitoes and (b) mean virus titer (determined by FFA in Vero cells) in the head/legs of mosquitoes with a disseminated infection as a function of mosquito isofemale families, virus isolates, experimental blocks, and their interactions.
