Life history and importance of the clover root borer, Hylastinus obscurus (Marsham) (Coleoptera: Scolytidae) in Quebec.

The importance of red claver (Trifolium pratense) as a forage crop; growing concern about both seed and hay yields; the failure of almost continuous research on varieties, seed setting etc. to greatly improve the situation in Quebec, and preliminary surveys indicating a very high percentage of two year old plants infested by the clover root borer (Hylastinus obscurus (Marshem)), gave rise to these investigations. It has been generously supported by a grant-in-aid for the purpose, from the Quebec Agricultural Research Council to Dr. Frank Morrison.
