FLIGHT ACTIVITY, WITHIN THE TRAP TREE ABUNDANCE AND OVERWINTERING OF THE LARCH BARK BEETLE (Ips cembrae) IN CZHECH REPUBLIC     pdf     HR     EN 19
Abstract
The increasing threat to forests from the gradual increase in Ips cembrae abundance necessitates more precise information concerning its ecology, monitoring, and control.
Cembräwit® pheromone traps and trap trees were used to evaluate I. cembrae flight activity and infestations, respectively, during outbreaks in 2007–2009 in the Czech Republic. Emergence of the next generation was also evaluated from trap logs and forest litter.
Flight activity was detected from late April to early July and lacked clear peaks. Trap trees were invaded evenly along the entire profile of the trunk. Parent galleries were longer and numbers of larval galleries were fewer in the upper parts than in the lower parts of trap tree trunks. Gradual fly-out of beetles from infested larch wood under laboratory conditions during winter confirmed that adults, larvae, and pupae of the offspring generation overwinter in such wood. The trapping of beetles emerging from litter confirmed that I. cembrae also overwinters in the litter near the trees where development was completed.

Key words: Ips cembrae; pheromone-baited trap; trap tree; flight activity; dispersion; overwintering
