Özet

This study is conducted between the years of 2006 and 2008 in Mut District of Mersin Province. In the trial, the efficacy of the mating disruption technique (MD) was investigated by using Isonet-A (E-5-decenyl acetate 98-99.5%, E-5-decenol 0 5-2%, 140 mg) pheromone dispensers for the management of Peach twig borer [Anarsia lineatella Zeller, 1839 (Lepidoptera: Gelechiidae)]. The pheromone dispensers were applied at 4 dispensers per tree (1000 dispensers per hectare) in 2006 and 3 dispensers per tree (800 dispensers per hectare) in 2007 and 2008 The MD technique was applied one time in a year using 3600, 2650 and 2700 dispensers in the years 2006, 2007 and 2008 respectively It is determined tat the emission amounts of pheromone dispensers were 1,13 g/ha/day in the first year and 1,22 g/ha/day in the second and third years Fruit damage was evaluated by inspecting 1000 fruit at harvest each year. In 2006, the average infestation rates were 6 17 and 4 60% in MD and chemical control (CC) orchards, whereas the rates were 5.51-1.92% and in 2007 and, 4 26-1 66% in 2008, respectively. As a result of this study, it was determined that the usage of 750-800 dispensers in apricot orchards in Mut would provide effective control of A lineatella Besides, the cost of MD technique was found 10.00 TL higher than the cost of CC
