Seasonal development of the timberman beetle Acanthocinus aedilis (Linnaeus, 1758) (Coleoptera: Cerambycidae) in the North-Eastern Steppe of Ukraine

Abstract

The earliest dates of timberman beetle development, duration of different stages and respective sums of positive temperatures have been calculated in the North-Eastern Steppe of the Ukraine. It was found, that timberman beetle more often hibernates as adult, but the part of population hibernates as larvae and continues to develop the next spring. The beetles, which hibernated, colonize trees or logs at the end of April. The first larvae hatch at the end of April – at the beginning of May. The first pupae appear at the beginning of August, the first adults of the new generation emerge at the end of August. Adults, which developed from hibernated larvae, colonize trees or logs in summer.
