Pierce, W.D. 1907. On the biologies of the Rhynchophora of North America. Nebraska State Board of Agriculture Zoological Report (1907): 247-319.
In the place of submitting myself a report for publication this year in the annual volume of the State Board of Agriculture, it has seemed to me appropriate to print a thesis for an advanced degree which was offered by one of the students in this department last year. Mr. Pierce has devoted a long time to the study of the biology, life histories, and activities of the group of weevils which are so numerous in every situation and so destructive to all varieties of plant life. The primary element in meeting their ravages is to secure knowledge of what particular form is at work and in what manner it carries out its devastations, what parts of the food plant are attacked and where the different phases of its life cycle are passed.
