A study of the clover root borer, Hylastinus obscurus (Marsham) (Coleoptera: Scholytidae).

By far the most important legume grown on Quebec farms is red clover, Trifolium pratense L. It has, however, been falling short of its potential productivity in this area. Within recent years, considerable research has been conducted with a view to evaluating the effects of various factors on the longevity and vigour of the red clover plant. The current view is that a complex of interacting factors, including varietal differences, weather conditions, and the attack of a large number of insect species, fungus diseases and possibly nematodes is involved in reducing the yield of this crop.
