Sažetak
An eruption of conifer bark beetle populations in Croatia that started after the drought year 2003 seems to be slowing down in 2008 and especially in 2009. According to the monitoring data and amount of timber that is being cut through salvage cuttings, spruce bark beetles are showing obvious three-year decline trend. This is even more pronounced with the silver fir bark beetles. It is hypothesized that this is a result of beneficial environmental conditions, buildup of natural enemy complex, reduction of host availability and intensive forestry activities. A newly recognized tree killing pest, Tomicus destruens, received special attention and through a detailed phenological screening it manifested a one year cycle in mid-Adriatic climatic conditions.
