Gnamptogenys striatula is a polygynous ponerine ant, whose colonies contain either several differentiated queens or several gamergates. Population structure, queen mating frequency and deviation from random mating were investigated in a north‐eastern Brazilian population. Eight workers from each of 33 queenright colonies and 17 queens and their progeny (20–40 offspring) were genotyped using eight variable microsatellite marker...

The genetic variability of honeybee populations Apis mellifera ligustica , in continental Italy, and of A. m. sicula , in Sicily, was investigated using nuclear (microsatellite) and mitochondrial markers. Six populations (236 individual bees) and 17 populations (664 colonies) were, respectively, analysed using eight microsatellite loci and Dra I restriction fragment length polymorphism (RFLP) of the cytochrome oxidase I ( COI...
