A Study on the Biology of the Barred Fruit-tree Tortrix [Pandemis cerasana (Hübner, 1786) (Lepidoptera: Tortricidae)] be Detected in the Cherry Orchards in Turkey
Pandemis cerasana (Hübner, 1786) (Lepidoptera: Tortricidae) causes economic damage by wrapping the leaves and bouquet of cherry fruit with the secreted silky strands and by gnawing the ripe fruits. This study was carried out in 2007-2009 to determine morphological characteristics and biology of P. cerasana in 0900 Ziraat variety cherry orchard in Sultandağı district of Afyonkarahisar province, Turkey and laboratory conditions. The relationship of P. cerasana biology with climate and cherry phenological features has been investigated. As a result of biological studies, adults were caught to pheromone trap in the cherry orchard in the third week of May in 2007-2008, reach to peak twice and continue to fly until October in both years. Adults laid eggs on the upper surface of the leaves in May-June for the first generation and in July-August for second generation. The larvae caused damage from April to October 2007-2008. Some second-generation larvae were overwintered as the first and second instar larva, and this pest has two generations per year. In the laboratory conditions, the average lifespan of P. cerasana was 8.48 days for males, 10.12 days for females, egg hatching time was 7.08 days, developmental time of larva was 32.58 days and developmental time of pupa was 7.21 days.
