Abstract
Acanthocinus aedilis has one generation if the Left-bank Ukraine. Swarming begins after stable transition of air temperature over 5ºC, averagely for region on April 7. Adults are the most injurious at maturating feeding in the middle of May, adults of new generation in August. Adults prefer for maturating feeding and colonization the trap logs and branches located in the most lightened (western) parts of clear-cuts and unclosed plantations. They colonize the trees of the IV–V categories of sanitary condition, as well as windbreak, windfall and felled in spring trees. The most part of pupae chambers of A. aedilis (83.9 %) are located inside the bark. Total injuriousness of this insect is assessed from 12.6 to 21.0 points, which respect to moderately injurious insects. The lowest risk of colonization of felled trees by A. aedilis occurs at its location in the northern part of clear-cut.
