Extract

During the summers of 1973 and 1974 examination of field collected samples of the spruce budworm, Choristoneura fumiferana, revealed the presence of a Pleistophora sp. (Wilson 1975). It has subsequently been determined as Pleistophora schubergi (Weiser 196 1 and pers. comm.). This microsporidium also appeared in laboratory cultures of the forest tent caterpillar, Malacosoma disstria. M. disstria is often infected in nature by the microsporidium Nosema disstriae. Preliminary tests were undertaken to compare the effects of these two microsporidia on the development of the forest tent caterpillar.
