Sciaphobus squalidus, Gyll. (Col., Curcul.), a Pest of Orchards in Ukraine

Abstract

Various species of Curculionidae are injurious to orchards in Ukraine, but Sciaphobus squalidus, Gyll. (fig. 1) is considered by fruit-growers to be the most harmful, as it attacks the buds of all fruit trees. Mr. Znamenskii was the first to make an adequate study of the life-history of this insect. The following notes give an account of my own observations and deal principally with methods of control.
