Title:Studies on the Contagious Diseases of Insects
Author(s):Forbes, Stephen Alfred
Subject(s):insect diseases
insect species
injurious insect species
bacterial forms
Abstract:Since August, 1883, the writer has used such opportunities as came in his way for observation of the diseases of insects, and for more or less careful and systematic work upon them, directed especially to the point of artificially propagating them for the destruction of injurious insect species. While these researches are not by any means completed, lacking especially critical study of the bacterial forms dealt with, as botanical species, and imperfect also on the side of field experiments on a large scale. I have thought them worthy of present report as a contribution to progress on a difficult but interesting subject, especially as opportunity for further continuance of some of these studies may not soon return.
