Effectiveness of protective measures against spruce bark beetle (\kur{Ips typographus} (L.)) at selected localities of LZ Boubín
 VAČKÁŘOVÁ, Tereza
The efficiency of various protective measures against the Spruce bark beetle (pheromone-baited traps, trap trees, poisoned traps - tripods.) and the impact of insecticide-treated trap trees on non-target organisms were studied in weekly periods in areas in the altitude of 1000m above sea level. Tree traps proved to be of much higher effectivity with an average of 3307 caught spruce bark beetles in comparison with pheromone-baited traps with only 457 beetles within the same period. Poisoned traps ? tripods baited with pheromone (FeSex Typo, producer ? Karel Ubik, CR) were more effective than pheromone traps and the average number of caught beetles was 1226. Among non-target insects caught in these traps were 61 species included 7 orders. The most common species was Thanasimus formicarius.
