Research on the biology, damage and struggle of IPS sexdentatus in Torul, Gumushane

This study was conducted to determine damage, biology and control of Ips sexdentatus, in forest areas in Gümüşhane province Torul Country in 2009-2010. Eleven different trial areas were selected in Torul region, where are Scots pine stands throughout the year as a result of the scans. In order to determine adult flight period and population density, 32 pheromone were hung and 11 trap tree. Insects trees, trees trap and pheromone traps in the trial areas were monitored periodically and stages of insect development has been observed. Barks were peeled with axes and shell apparatus and results were evaluated.In this study, Thanasimus formicarius (L.) and Rhizophagus depressus (F.) 's, the enemies of Ips sexdentatus were found. It was determined that insects trapped by pheromone were more than trap trees. In the same way, it was found that peeing with machine more effective than hatchet peeling. In peeling with ax, 40,73% of adults, 36,27 % of larvae and 36,92 % pupae died, while peeling with machine, 72,43% of adults, 69 % of larvae and 67,17 % pupae died.Key words: Scots pine, Ips sexdentatus, trap tree, pheromone, Torul.
