Title:Sixth Contribution to a Knowledge of the Life History of Certain Little-known Aphididae
Author(s):Weed, C.M.
Subject(s):corn plant louse
Abstract:The literature and life history of the corn plant louse were discussed at length in 1884 by Professor H, Garmauf, who showed that at that time nothing definite was known concerning the time or place of development of the sexed forms, the connection between the root and aerial forms, or the manner in which the insect passes the winter. In the article cited the author adds nothing of importance to our knowledge of either of these points, though the conjecture is made " that the lice hibernated as alate viviparous females."
