Oak borer beetles of Buprestidae family in forest regions of Gilane Gharb city, Kermanshah province

The oak decline phenomenon, causes drying of crowns, decreasing the radial growth and eventually the death of oak trees. The first step in conduction a management program for control of this phenomenon is. Identification of the factors which are related to oak decline, is the first step in management of this phenomenon in Zagros oak forests. The aim of this study was collecting and identifying the oak borer beetles in the forests of Gilane Gharb region in southwestern of Kermanshah province. The required data were obtained by direct observation and field sampling. The samples were collected based on a systematic sampling pattern in 90 square plots (50 × 50 m) and all trees were surveyed in each plot. The borer beetles were collected by splitting the dried branches, cutting the trunk and branches and keeping them in proper condition. In this study, the damage symptoms of the borer beetles were observed on 61.3 percentage of oak trees. The collected buprestid borer beetles on the oak trees were identified as following:Acmaeodera (Acmaeotethya) degener (Scopoli, 1763), Acmaeodera (Acmaeotethya) ottomana (Frivaldszky von Frivald, 1840), Acmaeodera (Acmaeotethya) undulata (Abeille de Perrin, 1891), Acmaeodera (Acmaeodera) wethloi (Obenberger, 1940), Acmaeoderella (Carininota) impunctata (Abeille de Perrin, 1891), Capnodis anthracina (Fischer, 1830), Capnodis cariosa hauseri (Obenberger, 1928), Chalcophorella (Stigmatophorella) bagdadensis (Laporte & Gory, 1836), Chalcophorella (Stigmatophorella) escalerae (Abeille de Perrin, 1904), Perotis lugubris longicollis (Kraatz, 1880), Svatactesis johanidesi (Bílý, 1997). The most abundant species were P. lugubris, C. cariosa, A. undulata and A. wethloi, respectively.
