Abstract：Samples of queens，workers and drones from five colonies of wild Bombus ignitus Smith were assessed at theB118，B11，B96，B124 and B126 microsatellite loci to analyse levels of polyandry． 3，2，3，4 and 3 father genotypes，respectively，were found in workers from the five colonies，indicating that the respective queens had each mated with 3，2，3，4 and 3 males． These results suggest that polyandry is common in B． ignitus colonies as with other species ofApidae，and that the average number of males with which each queen had mated was 3．
