<i>Wolbachia</i> density in testes.

Wolbachia densities in mosquito testes were measured by quantitative PCR as the ratio between the number of copies of the Wolbachia wsp gene and the C. pipiens ace-2 nuclear gene. The colored dots represent the average density of Wolbachia in a pool of three pairs of testes and the red strips represent the average Wolbachia density for each line/wPip strain. Letters represent the different statistical groups (i.e. means with the same letter are not significantly different), showing that Lavar males harbored significantly less Wolbachia in their testes than the other males.
