Figure 2.

Effect of family × isolate interactions on viral RNA concentration in mosquito bodies and virus titer in heads/legs. (a) The log-transformed viral RNA copy number per μl of homogenized body (thorax+abdomen) in infected mosquitoes and (b) log-transformed mean number of fluorescent focus units (FFUs) in the head/legs of mosquitoes with a disseminated infection as a function of mosquito families and virus isolates. In both panels, three isofemale families from a Ratchaburi population (A, B, and C) are ranked on the x-axis according to the mean proportion of infected mosquitoes across isolates (consistently with Figure 1). Each line represents a single virus isolate (BKK: Bangkok; KPP: Kamphaeng Phet; RTB: Ratchaburi). Each point represents the mean and vertical bars are the standard errors of the means. Crossing lines give an indication of family × isolate interactions.
