Pupae and adults of 4 Apis dorsata F. colonies from northern Thailand were collected in liquid nitrogen. DNA was extracted, and microsatellite genotypes at 3 loci determined for 42-194 workers per colony. From these data, the queen genotype was inferred, and the number of males with which each queen mated deduced. These A. dorsata queens mated with a mean of 26.75+-5.42 (SEM) drones (range, 13-39). The mean within-colony genetic relatedness was 0.29+-0.009. All colonies were monogynous. Possible reasons for the very high level of polyandry and the great variance are discussed. A null allele was detected for 1 microsatellite locus in 1 queen progeny.
