Akdağ Nature Park is situated in Sandıklı province of Afyonkarahisar city in the inner western part of Anatolia. As the research area Akdağ Nature Park which was established as Nature Park in 2000 in terms of its resource values, is a valuable area in terms of its flora and fauna. The Anatolian Black pine (Pinus nigra) is the most common trees species that distributed in the middle and northern part of the stand. In addition to this, Pinus sylvestris, Juniperus spp., Quercus cerris, Q. coccifera and Populus tremula are other considerable forest tree species in Akdağ Nature Park. Sometimes, pest insects are among the various factors that affect the health of forest trees.
This study was carried to determine flight activity of Ips sexdentatus (Börner), Tomicus minor (Hartig), Anisandrus dispar (Fabricius) and Xyleborinus saxesenii (Ratzeburg) in 2015. For this aim, red winged sticky traps (by an attractive mixture of 96% ethyl alcohol and 1% toluene) and funnel type pheromone traps were settled. The funnel type traps were hanged in pure and also mixed with P. sylvestris stands of Pinus nigra. The flight activity of I. sexdentatus and T. minor were observed by funnel type pheromone traps by controlling every two weeks. The red winged sticky traps were hanged for determining to flight activity of A. dispar and X. saxesenii on the branches of Quercus trees at a height of 2-2.5 m at a distance of at least 80-100 m from each other. Controls were performed weekly in red winged sticky traps and were continued until the end of adult catching.
As result of study, it was determined that Ips sexdentatus was bivoltine in Akdağ Nature Park. The first flight period started in the mid of April and also second generation started to fly in the end of July. Also, Tomicus minor adults started to fly in the end March and flight period continued till to mid of April.
First adults of Xyleborinus saxesenii were detected in the red winged sticky traps during 2015 starting from the mid of April. It is observed that the flight activity continued until the end of September. The third week of August was when the number of adults caught in the traps was the highest. Also, flight activity of Anisandrus dispar started in the mid of April and population reached the highest level in the second week of May. Adults were coughed till the mid of August.
