Isolation and characterization of 30 polymorphic microsatellite loci from the mycophagous fly Drosophila innubila.

Drosophila innubila is a mushroom-feeding member of the quinaria group, found in the woodlands and forests of the 'sky islands' in Arizona and New Mexico and extending south into central Mexico. Here, we describe and characterize 30 polymorphic microsatellite loci from D. innubila collected in the Chiricahua Mountains in Arizona. The number of alleles ranged from three to 21, and observed heterozygosity ranged from 0.0513 to 0.9737. Six loci were putatively X-linked, six departed from Hardy-Weinberg equilibrium, seven had evidence of null alleles, and six showed evidence of linkage disequilibrium. These markers will be useful for examining population structure of D. innubila and its association with male-killing Wolbachia.
