Abstract
The current study was carried out in 2018-2019 at good agricultural practices of walnut orchards to control with mass-trapping and determination of damage rates of codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae) in Hatay province of Turkey. The study was conducted at 312.43 decares good agricultural practices of walnut orchards containing 3,928 number of Chandler varieties tree, located at the Kışlak village of the Yayladağ district of Hatay province. Delta traps with codling moth pheromones were used. Traps were hanged 1.5 m high, pheromone capsules were replaced with new ones in every forty days. In the first year, a total of 235 codling moth adults were caught by the 50 delta traps during the sampling period. The average population density of adults caught by traps was determined to be 4.61. In the second year, a total of 70 codling moth adults were caught by the 50 delta traps during the sampling period. The average population density of adults caught by traps was determined to be 1.4. In the first year, a total of 38,400 walnut fruits were harvested and a 100 walnut fruit was harmed by the codling moth larvae. Thus, the damage rates of the codling moth were estimated as 0.26 percent. In the second year, a total of 443,100 walnut fruits were harvested and a 9,065 walnut fruit was harmed by the codling moth larvae. Thus, the damage rates of the codling moth were estimated as 2.04 percent.
