Taxonomic diversity and distribution of beetles (Insecta: Coleoptera) occurring in Central Lithuania

2007–2012 metų metu buvo atlikti Coleoptera būrio įvairovės tyrimai Strošiūnų šile ir Ukmergės priemiestiniuose miškuose, o papildoma medžiaga surinkta Vilniuje ir Klaipėdoje. Apibūdinus ir sutvarkius medžiagą paaiškėjo, jog iš viso identifikuotos 307 vabalų rūšys, priklausančios 47 šeimoms. Atlikus tyrimus buvo aptiktos 7 rūšys, įrašytos į Lietuvos raudonąją knygą: Liocola marmorata, Carabus nitens, Xylodrepa quadripunctata, Cucujus cinnaberinus, Prionus coriarus, Peltis grossa, Necydalis major. Tyrimų metu taip pat buvo įdentifikuota 30 rūšių, kurios yra labai retos, o 67 – retos. Strošiūnų šile aptikta viena vabalų rūšis (Laemophloeus muticus), kuri yra nauja Lietuvos faunai. Buvo aptikta viena nauja Cucujus cinnaberinus radavietė Ukmergės priemiestiniuose miškuose.Intensive field work of 2007–2012 in Strošiūnai Forest and Ukmergė (Lithuania) confirmed the occurrence of 307 species of beetles belonging to 47 families of Coleoptera (280 species of beetles belonging to 45 families in Strošiūnai Forest only). Most of the identified species belong to Carabidae (46 species), Chrysomelidae (34 species), also to Cerambycidae (28 species) and Curculionidae (23 species). Seven species of Coleoptera are included into the Red Book of Lithuania: Liocola marmorata, Carabus nitens, Xylodrepa quadripunctata, Cucujus cinnaberinus, Prionus coriarus, Peltis grossa, Necydalis major; 30 other recorded species are rare in the country (incl. Laemophloeus muticus is new to the Lthuanian fauna). „Ipsodor“ pheromone (Z.D. Chemija) made for attracting of bark beetles was used in pheromone traps and larger part of the specimens in Strošiūnai šilas forest was collected by these traps. During the search for Cucujus cinnaberinis and Boros schneideri drying or died trees with trunks of 20cm or wider were checked (pine trees affected by xylophagous insects – for B. schneideri; willows, aspen, oak and elm trees affected by xylophags – for C. cinnaberinus) A license to search for new habitats of Cucujus cinnaberinus and Boros schneideri in key forest habitats (KFH) ok Kaišiadorys and Ukmergė districts was issued by Environmental Protection Agency in 2011. Most of the selected KFH territories were atypical for living of Boros schneideri, but trees suitable for Cucujus cinnaberinus were detected in almost all the habitats. Unfortunately, beetles were found only in one of the eight selected KFH, but the population looked viable in that one habitat with more suitable oaks nearby, although outside the territory of KFH.Švietimo akademijaVytauto Didžiojo universiteta
