Abstract

Anabrus simplex is an economically significant crop pest in the western United States and is a model organism for studying the influence of sex role reversal on sperm allocation and utilization patterns and population genetics. We isolated seven polymorphic microsatellite loci in Anabrus simplex, and within population allele numbers ranged from 10 to 25. High polymorphism is not unusual for Orthopteran insects, although observed heterozygosities ranged from 0.24 to 0.91 and were lower than expected heterozygosities, suggesting null alleles. These microsatellites will greatly facilitate studies of postcopulatory reproductive isolation in nuptial gift-giving insects and historical phylogenetics in the Rocky Mountains.
