The study was carried out for control of codling moth in the apple orchards of the Fruit Research Institute in 2008 and 2009. The orchards were comprised of Golden Delicious and
Starking Delicious cultivars grafted on the seedling rootstock. There were two different treatments; mating disruption (MD) plot (1.5 ha in size), and control (C) plot (1 da in size). Isomate
-C- Plus type of dispensers, containing 190 mg of active ingredient (E,E-8,10-Dodecadien-1-ol), were used as 1.000 pieces per hectare for all trees in the MD plot. In both MD and C plots, the insecticides were used Spirodiclofen, propargite (for mites), and imidacloprid (for aphids). Insecticides were not used for codling moth in both plots. In the study, fruits were collected from 30 trees in the MD plot while 10 trees were sampled in the C plot. The infected fruits were counted and the rate of infected calculated in percent. In the MD plot, the percentage of infected fruits was 2.38% in 2008 and 13.50% in 2009. In the C plot, the percentage of infected fruits was 72.07% and 64.05% in 2008 and 2009, respectively.

Bu çalışma, Meyvecilik Araştırma Enstitüsü elma bahçelerinde elma içkurdu ile mücadele amacıyla 2008-2009 yıllarında yürütülmüştür. Bahçeler, çöğür anacı üzerine aşılı olan Golden Delicious ve Starking Delicious elma çeşitlerinden oluşmuşlardır. İki farklı uygulama bulunmakta olup bunlar çiftleşmeyi engelleme yöntemi parseli (ÇEY) (1.5 ha) ve kontrol (K) parselidir (1 da). ÇEY uygulanan parseldeki tüm ağaçlarda, hektara 1.000 adet, 190 mg aktif madde içeren (E,E-8,10- Dodecadien-1-ol) Isomate-C- Plus yayıcılar kullanılmıştır. ÇEY ve K parselinde insektisit olarak kırmızı örümcekler için spirodiclofen, propargite; yaprakbitleri için imidacloprid kullanılmıştır. Elma içkurdu için her iki parselde de insektisit kullanılmamıştır. Çalışmada, ÇEY parselinde meyveler 30 ağaçtan toplanırken, K parselinde ise 10 ağaçtan meyve örneklemesi yapılmıştır. Kurtlu meyveler sayılarak kurtlanma oranı % olarak hesaplanmıştır. Yapılan çalışmada, ÇEY uygulanan parselde kutlanma oranı 2008 yılında %2.38, 2009 yılında ise %13.50 olmuştur. K parselinde kutlanma oranı ise 2008 ve 2009 yılında sırasıyla %72.07 ve %64.05 olarak gerçekleşmiştir.
