Abstract
During studies on the control of the onion maggot, Hylemya antiqua (Meig.), in late September, 1958, from one to 10 dead adults were found clinging to the tops of onion leaves in a three-acre field of green bunching onions in the Toronto area (Fig. 1). The dead flies were more abundant in the outside three rows, adjoining a non-cultivated grassy area, than throughout the rest of the field. A fungal growth was evident between the abdominal terga and sterna in many specimens. Infected live flies were somewhat pale, appeared bloated, and moved very sluggishly in comparison with non-infected adults. Dead flies were sent to Dr. G. Bucher, Entomology Laboratory, Belleville, Ontario, who identified the pathogen as Empusa muscae Cohn.
