On the vertical distribution of Ips duplicatus, I. cembrae and some bark- and longhorn beetles (Col.: Curculionidae, Scolytinae; Col.: Cerambycidae) in the Tatra National Park in Poland
In 2013–2014, a set of 30 pheromone traps baited with synthetic lures attracting I. duplicatus (Duplodor – 15 traps)
and I. cembrae (Cembrodor – 15 traps) was installed in 6 altitudinal transects (1000–1400 m a.s.l., every 100 m of
elevation) in the eastern, central and western part of the Tatra National Park (TPN) in Poland and operated during
the entire growing season. The main aim of the survey was to check if and to what vertical extent these two species
of bark beetles, not yet recorded, are presently distributed in TPN. Collected insects, including non-target Scolytinae
and Cerambycidae, were determined. Overall 1896 Scolytid bark beetles belonging to 13 species, all occurring in
the whole elevation range, were collected. I. duplicatus (28 specimens in total) was collected in the whole elevation profile, similarly as I. cembrae (718 specimens in total). Among Cerambycidae (282 individuals) belonging to
19 species, Rhagium inquisitor and Pidonia lurida, found on all elevations, were the most abundant; 8 species were
collected on the highest locality. Pogonocherus decoratus was found for the first time in the Tatra. Results indicate
the upward spreading of the studied insects as a possible effect of climate change and the resulting environmental
conditions favourable for those organisms.
