Fungus Inoculation for Insects

Abstract

THE importance attributed by Dr. Lankester (NATURE, vol. xxi. p. 448) to “Prof. Metschnikoff's suggestion of a deliberate cultivation of an insect's-disease-producing fungus, and the application of the cultivated fungus in quantity to places infested by these insects,” invites attention to the fact that the suggestion has been anticipated in a very serious and earnest way by my friend the distinguished entomologist, Dr. John L. Le Conte of Philadelphia, in his presidential address before the Portland meeting of the American Association for the Advancement of Science, in August, 1873.
