The General Entomological Ecology of the Indian Corn Plant

A prolonged study, extending over many years, of the entomology of the corn plant, the economic results of which have been published in my seventh and twelfth reports as State Entomologist of Illinois (the Eighteenth and Twenty-third of the office series), has left in my possession a considerable body of information capable of treatment from the standpoint of pure ecology, and the beginnings of such a treatment are here assembled because of the rising interest in ecological investigation and the promise which it gives of interesting and important results, and becauseof a wish to illustrate in some measure the general scientific value of such materials of which, it scarcely need be said, the economic entomologists of this country have accumulated a large amount.
