Abstract

This study aims to evaluate the trapping effectiveness of two types of pheromones, the Austrian (Acuwit ®) and the Spanish one, in order to improve monitoring techniques and integrated control of Ips acuminatus Gyll., a bark beetle which since 2004 has caused serious damage to pine forests in the Cadore valley. Other aims of this study are: to compare the number of beetles and non-target species caught by traps, in four types of stand (healthy open areas, healthy woody areas, infested areas with standing trees and infested areas with felled and not removed trees); to describe the voltinism of Ips acuminatus and to identify the relationship between the number of caught beetles and damage level in 2008 and 2009. The Spanish pheromone was more attractive for Ips acuminatus and non-target species, whereas other bark beetle species were, more attracted by the Austrian lure. Ips acuminatus occurrence was different between the stand type and years. In healthy open areas traps caught more beetles than in infested ones, with the highest values in 2009, whereas in infested areas the number of caught beetles and the damage where lower in 2009. The number of infested trees was positively related to the number of caught beetles, especially in the infested stands where trees were felled but not removed.
