Application of the Mating Disruption Technique Against Codling Moth Cydia pomonella (L.) (Lepidoptera: Tortricidae) in Kahramanmaras Province

Abstract

In this study, Isomate-C Plus pheromone dispensers were used in the application of the mating disruption method (ÇE) against codling moth Cydia pomonella (L.) (Lep.: Tortricidae) in 2018-2019. The study was carried out on ten decares of Braeburn, Red Gala, Red Fuji, Mondial Gala, Red Chief, Galaxy Gala, Golden Smith, and Golden B apple cultivars in Onikisubat district of Kahramanmaraş province. As the control area disruption technique (ÇE), Isomate-C Plus pheromone dispensers, between April and October, against Apple borer (KA), the 15 da Granny Smith, Golden, and Starking studies were carried out in Tekir, which is connected to the Onikisubat district of Kahramanmaraş province. In 2018, the total number of adult C. pomonella in the field of CE was 37, while the infestation rate was 9.07 %. Against the 1st and 2nd generations of C. pomonella, 2 times Bacillus thuringiensis ssp. kurstaki were used with mating disruption treatment. The release rate of Isomate-C Plus pheromone dispensers used in the EI field until the harvest was 12.34 %. In KA, the total number of adult C. pomonella was 1.136, while the infestation rate was 43.69%. Insecticide was applied six times against C. pomonella in KA by the producer. Likewise, in the CE field, the total number of adult C. pomonella was 18 in 2019, while the infestation rate was 8.38%. Against the 1st, 2nd and 3rd generations of C. pomonella 3 times Bacillus thuringiensis ssp. kurstaki were used with mating disruption treatment. The release rate of the Isomate-C Plus pheromone emitter used in the EI field until the end of the harvest was 10.95 %. In KA, the total number of adult C. pomonella was 1.256, while the infestation rate was 38.93%. Insecticide was applied six times against C. pomonella in KA by the producer. As a result of the study, the mating disruption technique can be used against C. pomonella on a large scale, unless a biological insecticide should support it as Bacillus thuringiensis ssp. kurstaki as infestation rate exceeds the economic threshold levels (5 %).
