HOST DETERMINATION OF CHALCIDOID AND PROCTOTRUPOID HYMENOPTERA ASSOCIATED WITH TWO SPECIES OF MIDGES (DIPTERA: CECIDOMYIIDAE) FOUND IN NEEDLE GALLS OF BALSAM FIR
Published online by Cambridge University Press: 31 May 2012
Abstract
Four species of Chalcidoidea: Tetrastichus marcovitchi (Cwfd.), Tetrastichus sp., T. whitmani (Grit.), Pseudencyrtus sp., and two species of Proctotrupoidea: Platygaster abicollis MacGown and Osgood and P. mainensis MacGown and Osgood were reared and identified as parasites of the balsam fir needle gallmaker, Paradiplosis tumifex Gagné. T. marcovitchi was the most abundant. No parasites were found on or reared from Dasineura balsamicola (Lintner). The rearing technique is given.
