HOSTS AND DISTRIBUTION OF SPRUCE CONE MAGGOTS ( STROBILOMYIA SPP.) (DIPTERA: ANTHOMYIIDAE) AND FIRST RECORD OF STROBILOMYIA APPALACHENSIS MICHELSEN IN CANADA

Abstract Two species of cone maggots, Strobilomyia Michelsen, are known to attack seed cones of spruces in North America. Seed cones of black, red, and white spruce from Newfoundland to Alberta were collected to determine the number of host species and the distribution of these maggots. Strobilomyia...

Description
Summary:Abstract Two species of cone maggots, Strobilomyia Michelsen, are known to attack seed cones of spruces in North America. Seed cones of black, red, and white spruce from Newfoundland to Alberta were collected to determine the number of host species and the distribution of these maggots. Strobilomyia appalachensis Michelsen was obtained only from seed cones of black and red spruce, whereas S . neanthracina Michelsen was obtained only from white spruce seed cones. Our observations represent the first record of S . appalachensis in Canada. We conclude that, like S . neanthracina , S . appalachensis has a transcontinental distribution, but exploits different hosts, namely black and red spruce. We also observed that S . appalachensis was capable of extended diapause.
