A fatal viral disease of bee larvæ.
1913G. F. White in Circular Bureau Entomol., U.S. Dept. Agric. No. 169. 1 Sacbrood..is no new disease.Ibid. 3 There is, therefore, a disorder attacking the brood of bees in which [the] brood dies, but in which there has not been demonstrated any microorganism to which the cause of the trouble could be attributed. For this disease the name of ‘sacbrood’ is here suggested.Ibid., Many larvæ dead of this disease can be removed from the cell without rupturing their body wall. When thus removed they have the appearance of a small closed sac. This character suggested the name ‘sacbrood’.1928R. W. Glaser in T. M. Rivers Filterable Viruses viii. 281 The number of colonies that die as a direct result of sacbrood is comparatively small; the loss of individual bees, however, in the aggregate is enormous.1967K. M.
