Extract

Laboratory rearing of the white cutworm, Euxoa scandens (Riley), a pest of flue-cured tobacco in Quebec and asparagus in Michigan, has been hindered to some extent by a disease. This note describes the microsporidium which caused the disease and techniques that inhibit the development of the pathogen.
