Distribution details in Romania

Situation
Current pest situation evaluated by EPPO on the basis of information dated 2022: Present, restricted distribution
First recorded in: 1948
Comments
According to Duduman & Vasian (2012): present in most of the Picea abies-growing areas at altitudes < 1000 m. Outbreaks have only been observed in Norway spruce plantations outside their natural range, in the North-Eastern part of the country (e.g. in 2009, it killed about 14 000 trees, between 30 and 50 years old).

According to Olenici et al. (2022): I. duplicatus was first collected in 1948 in the Eastern Carpathians (Rarău Mountain). Then it was sporadically found in many locations (mainly Eastern Carpathians at altitudes betweem 175 to 1 200 m). An outbreak took place from 2005 to 2014 in the notth-eastern part, killing more than 1.3 million trees. Surveys have shown that I. duplicatus is established in most parts of the Norway spruce's (Picea abies) range.
