The wrinkled fruit tree sapling beetle ( Scolytus rugulosus ) is a weevil from the subfamily of the bark beetle (Scolytinae). Since it creates its breeding systems in the bark of the host trees, it is counted among the bark breeders.
features
The beetles are 1.8 to three millimeters long and have a black, cylindrical body. The pronotum is large and narrowed in front, the base and sides are edged. Seen from above, it does not cover the head. The points on the pronotum are large, elongated, and often fused into longitudinal wrinkles. The forehead of the male beetle is flat and dense, with short hairs, the forehead of the female beetle is arched and not very hairy ( sexual dimorphism ). The forehead has no longitudinal keel. The elytra have uniform rows of dots that are close together and sometimes run into longitudinal wrinkles. The wing covers are colored red and have a dark central band and dark side patches. The abdomen rises obliquely from the second sternite , which is without a spinous process, towards the end. The rails ( tibia ) of the forelegs are smooth on the outside and have a hook-shaped curved tip. The third tarsal link is bilobed.
distribution
The species is distributed in central , southern and southern northern Europe , the northern Caucasus and the Crimea .
Way of life
The wrinkled fruit tree sapwood beetle is found mainly on Prunus , apples ( Malus ), pears ( Pyrus ), roses ( Rosa ), more rarely also on birches ( Betula ), alders ( Alnus ), elms ( Ulmus ), beeches ( Fagus ) and hazelnuts ( Corylus avellana ). It colonizes the bark of the trees. The feeding pattern is a one-armed mother duct (longitudinal duct) from which the larval ducts branch off to the side. The species forms one to two generations per year, the flight time is from June to July. The beetles are monogamous .
