Twenty diseased and 17 control bees were studied grossly and histologically with respect to pathological manifestations of an adult bee disease (tentatively called hairless-black syndrome), which has not been clearly distinguished in the literature from several other diseases of adult bees. In a diseased bee as compared with a control, the abdomen was abnormally distended by an accumulation of unusually aqueous feces; the midgut was often white and translucent instead of brown; the lumen of the small intestinal portion of the hindgut contained an increased amount of basophilic material, probably intestinal flora; the wall of the small intestine had large lesions and necrotic appearing areas in about half of the cases; the cytoplasm of the small intestinal epithelial cells consistently contained small, spherical, basophilic granules; and finally the neuropile of most thoracic and abdominal ganglia were surrounded by extremely small basophilic granules. It is concluded that hairless-black syndrome is different from both chronic and acute bee paralysis, but may be the same as “Mal Nero” in Italy and is probably the same disease as that described from Great Britain by Morison under the name “bee paralysis”. ☆This paper is a portion of a thesis submitted by the senior author and accepted by The Ohio State University in partial fulfillment of the requirements for the degree Master of Science.
