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

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 lo...
