Popis:	Sphaerularia bombi Dufour is an internal nematode parasite of bumble bee queens in North America and Europe. Infection functionally castrates the bee. Here we document the prevalence and intensity of S. bombi infections in seven species of Bombus and three species of Psithyrus on Cape Breton Island, Nova Scotia, Canada. We found dramatic variation in prevalences among Bombus spp., and some evidence that prevalence increased as the nesting season progressed. Also, we report S. bombi in the bumble bee nest parasite Psithyrus insularis (Smith), the first record for the genus in North America.
