Abstract
Field-collected specimens of the large aspen tortrix, Choristoneura conflictana, are infected by several microorganisms, including granulosis virus, entomopoxvirus, three species of microsporidia, and three species of fungi. There are also mixed infections consisting of two or three microorganisms. Diagnostic results obtained between 1951 and 1978 demonstrate that widely separated geographic populations of this insect are affected by the same complement of microorganisms. Cross infection tests with microsporidia were carried out utilizing both laboratory-reared and field-collected insects. The results are inconclusive concerning the relationship of microsporidia in C. conflictana to those occurring in related insect species.
