Rezumat:

Ips duplicatus was collected in Romania for the first time in 1948.
Afterwards, between 1957 and 1967, it was found in different places, but only
as a faunistic element. The first outbreak of this species was reported in 2008
in spruce stands installed outside the natural area (the North-Eastern part of
Romania). Using pheromonal traps in 2010 we initiated the checking of its
presence in five locations of Suceava County, and the research continued in 2011
in thirty-one locations distributed within the most areas of the country where
the Norway spruce is growing, but only up to 1000 m altitude. Ips duplicatus
specimens were captured in most places. Most captures (about 2500 beetles/day)
were recorded in the Zamostea location (the North-Eastern part of Romania),
in an area where Ips duplicatus population attained the epidemic level.
