Abstract

Insect species collected in log depots in Western Black Sea Region of Turkey were identified. The study covered two years, 2015 and 2016, in 21 log depots in seven provinces (Duzce, Bolu, Zonguldak, Bartin, Karabuk, Kastamonu and Sinop). The study area was divided into three sub regions and each sub region was analyzed for insect species, their prevalence and intensities. Overall, four orders, 22 families, 74 genera and 57 species were described in log depots of the study area. Sub region 1 (Düzce-Bolu) showed the highest diversity in terms of insect species and sub region 2 (Zonguldak-Bartin) had the lowest diversity. Dorcus parallelipipedus Linnaeus, 1758 (Coleoptera: Lucanidae) and Rhagium inquisitor Linnaeus, 1758 (Coleoptera: Cerambycidae) were found in all provinces studied. Based on wood species analysis, Scots pine wood had the highest diversity in insect species, followed by fi r, oak and beech. The study also described some important wood-destroying insect species from the families Anobiidae, Buprestidae and Cerambycidae. Buprestis dalmatina (Mannerheim, 1837) (Coleoptera: Buprestidae), Leptura aurulenta (Fabricius, 1792) (Coleoptera: Cerambycidae) and Stictoleptura scutellata (Fabricius, 1781) (Coleoptera: Cerambycidae), all wood-destroying insect species, were identified for the first time in the Western Black Sea Region of Turkey.

Highlights

Summary

Introduction

With the greatest number of species on earth, either have contact with living trees or during the service life of forest product after harvest. These insect species consume wood as food sources or use it as shelter for their larvae. As a result, they can reduce physical, chemical and technological properties of wood within very short time. They can reduce physical, chemical and technological properties of wood within very short time They cause tremendous economic loss if the necessary precautions are not taken.
