Abstract:
Nine microsatellite loci were isolated from the genome of Laodelphax striatellus (Homoptera: Delphacidae) by constructing (TC)(6)(AC)(5) and (AG)(6)(AC)(5) compound SSR-enriched libraries using suppression-PCR procedures. These loci were found to be highly polymorphic, with 13 to 30 alleles per locus in the three populations that we investigated (Jiangsu, Shandong and Zhejiang). The observed and expected heterozygosities ranged from 0.255 to 0.833 and 0.392 to 0.929, respectively. These microsatellite markers can be used for the study of population genetic structure and genetic diversity of L. striatellus.
