摘要： The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemipeta: Pseudoccoccidae), is an aggressively invasive pest causing huge economic losses of crops around the world. In this study, we developed genome-wide microsatellites for population genetic analysis of P. solenopsis. We obtained a random genome of P. solenopsis with a size of 267.07 Mb and scaffold N50 of 14.12 Kb. In total 115,639 microsatellites were isolated from the genome, of which those with trinucleotide motifs were the most abundant. Forty-two polymorphic loci were selected for primer validation based on three populations. Allele numbers varied from 2 to 5 with an average value of 2.5 per locus, and allelic richness ranged from 1.00 to 4.48. The observed heterozygosity (H-0) and expected heterozygosity (H-E) ranged from 0.00 to 0.92 and 0.00 to 0.73, respectively. Population genetic structure analysis based on the developed markers revealed strong differentiation between three populations of P. solenopsis collected from its invasive range in China. The microsatellites developed in our study should provide efficient genetic markers for population level studies of P. solenopsis to reveal invasion history and patterns of dispersal.
