Results of using pheromone-baited traps for investigations of Osmoderma barnabita Motschulsky, 1845 (Coleoptera: Scarabaeidae: Cetoniinae) in Latvia

Osmoderma barnabita Motschulsky, 1845 is a threatened scarab beetle living in the hollows of old deciduous trees. Beetles of the genus Osmoderma are known for their fruity odour, which is released by males. Pheromone-baited traps were used for the first time for the study of distribution of O. barnabita in Latvia and new data about the species distribution were obtained. The capture-mark-recapture method was used to estimate dispersal ability of O. barnabita. Our results suggest that maximum dispersal distance (2090 m) observed in this study is the farthermost record from wild Osmoderma populations till now.
