Figure 1. Polyploid analysis of bisexual and parthenogenetic Asian longhorned tick populations in China. Ploidy of ticks was tested by using flow cytometry and measuring fluorescence intensity of cell nuclei stained with 4′,6-diamidino-2-phenylindole. A) Bisexual (2n) sample with a peak at the 66 position. B) Parthenogenetic (3n) sample with a peak at the 99 position.
