Determination of Population Development and Infestation Rates of Codling Moth [Cydia pomonella (L.) (Lep.: Tortricidae)] in Apple Orchards in Konya Province

Özet

The study was conducted to determine population development and infestationrates of codling moth (Cydia pomonella (L.) (Lep.: Tortricidae) in Selçuklu,Meram and Karatay districts in Konya Province. During 2017-2018, two appleorchards were selected from each district. Pheromone traps were used to monitor adult population development and infestation rates by counting weeklyinfested and not-infested apple fruits after fruit set stage of tree. Study resultsrevealed that, in all districts, adult population peaks were observed four andthree times in 2017 and 2018 in each year, respectively. It was determined that,codling moth might produce two-three generation depending on years andclimate conditions, in Konya province.. Flight period of codling moth adults, inorchards, started in thr second week of May and lasted at the end of October.Infestation rates were calculated for 2017 and 2018 in Selcuklu district 10.5%and 16.45%, in Meram district 21.3% and 30.15%; and in Karatay district20.5% and 33.9%, respectively
