Flight activity, within the trap tree abundance and overwintering of the larch bark beetle (Ips cembrae) in Czech Republic
Original language description
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 fl ight 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 Švehly along the entire profi le 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 fl y-out of beetles from infested larch wood under laboratory conditions during winter confi rmed that adults, larvae, and pupae of the off spring generation overwinter in such wood. Th e trapping of beetles emerging from litter confi rmed that I. cembrae also overwin
