Book Description
Excerpt from Fungous Diseases of the Honeybee The study of diseases of bees due to fungi has been much later in its development than the study of those caused by bacteria. Much the greater share of the attention of investigators of bee diseases has been given to the two serious bacterial brood diseases, American foul brood and European foulbrood, caused respectively by B lemme and B. Pluton. In America only two reports are on record of diseases of bees and their brood caused by hyphomycetous fungi. In 1896 Howard of Texas, described a new brood disease which he called pickled brood or white fungus, caused by a species of Aspergillus to which he gave the name Aspergillus Two years later he described (15) the same disease as occurring in both pupae and adult bees and stated his belief that this disease had been mistakenly diagnosed by beekeepers as paralysis. In both reports Howard gives descriptions and illustrations of the disease, which he called pickled brood or white fungus, which are more readily applicable to the disease known as sacbrood than to those caused by fungi. He ascribed this disease to the pathogenic Aspergillus, A. Pollini. The dead larvae are described as at first white and watery, later becoming black and swollen, and finally dry ing down to black scales. In no case was the fungus, which Howard assumes to be the cause of the disease, observed on the larvae, and isolations of the organism were not made. In adult bees the disease is described as causing black, shiny, apparently frozen abdomens. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Fungi of the Bee-Hive Higgins (14) in 1858 published an account of the death of some bees, caused, it was presumed, by a fungus. His description is, unfortunately, insufficient to determine the species which made its appearance on the dead bees, and which he did not name.

Book Description
Excerpt from The Occurrence of Diseases of Adult Bees, II In several instances, before the cause of the Isle of Wight disease was discovered, statements appeared in bee journals of the United States to the effect that the disease is present in this country, but as these records are without value they are not specifically mentioned. The symptoms described by beekeepers of Great Britain for the Isle of Wight disease were so nearly identical with some of those observed for diseases of adult bees in the United States as to make such belief plausible. As has been explained earlier (p. This can not be accepted as evidence that the disease is actually present.
