    Çanakkale ve Balıkesir illeri yumuşak çekirdekli meyve ağaçları ve yabancı otlar üzerinde bulunan bitki zararlısı akar türleri
    (2015) Kasap, İsmail; Çobanoğlu, Sultan; Pehlivan, Serkan; Kök, Şahin; Baştuğ, Gökhan
    Bu çalışma Çanakkale ve Balıkesir illerinde bulunan bitki zararlısı akar türlerini belirlemek amacıyla 2009-2011 yıllarında gerçekleştirilmiştir. Çalışma sonucunda Tetrancyhidae, Tenuipalpidae ve Eriophidae familyalarına bağlı 13 bitki zararlısı akar türü belirlenmiştir. Bitki zararlısı familyalar arasından Tetrancyhidae 5 cins ve 8 tür ile en önemli familya olarak belirlenmiştir. Bu türler içerisinde Tetranychus urticae Koch en yaygın tetranychid türü olarak bulunmuştur.

    Çanakkale ve Balıkesir illeri yumuşak çekirdekli meyve ağaçları ve yabancı otlar üzerinde bulunan predatör akar türleri
    (2013) Kasap, İsmail; Çobanoğlu, Sultan; Pehlivan, Serkan
    Özet: Bu çalışma Çanakkale ve Balıkesir illerinde bulunan predatör akar türlerinibelirlemek amacıyla 20092011 yıllarında gerçekleştirilmiştir. Çalışma sonucunda 11familyaya bağlı 35 predatör akar türü tespit edilmiştir. Predatör familyalar arasındanPhytoseiidae 9 cins ve 17 tür ile en önemli familya olarak belirlenmiştir. Bu türleriçerisinde Typhlodromus athiasae Porath and Swirski en yaygın phytoseiid türü olarakbulunmuştur. Bu avcı türler, yapılan bu çalışma ile bu alanlarda ilk defa tespit edilmiştir

    Effect of temperature on the life history and development of Typhlodromus athiasae Porath and Swirski (Acari: Phytoseiidae) as a predator of Tetranychus urticae Koch (Acari: Tetranychidae)
    (Systematic & Applied Acarology Soc London, Natural History Museum, 2023) Kasap, Ismail; Kok, Sahin; Pehlivan, Serkan
    The present study determined the effects of different temperatures on the life history parameters an d development of Typhlodromus athiasae Porath and Swirski (Acari: Phytoseiidae) for the first time. The stu dy was conducted at 20, 25 and 30 degrees C and the predators fed on Tetranychus urticae Koch (Acari: Tetranychidae) under laboratory conditions. Our results show that temperature significantly affected pre-adult and adult durations of T. athiasae. The adult longevity was calculated as 47.90, 22.88, 19.50 days for females, 26.11, 19.90, 20.46 days for males at 20, 25 and 30 degrees C, respectively. The adult females of T. athiasae laid 15.80 (eggs/ female), 17.20 (eggs/female) and 12.38 (eggs/female) eggs at the respective temperatures tested. The highest net reproductive rate (R0= 8.90 offspring/individual) determined at 25 degrees C but no significant difference was foun d among the other temperatures. The highest intrinsic rate of increase (r= 0.12 day-1) was observed at 25 degrees C an d 30 degrees C. Although the highest finite rate of increase (lambda= 1.13 day-1) was determined at 25 degrees C, no significant difference was observed between this temperature and 30 degrees C. Also, the shortest mean generation time (T=14.9 7 day) was obtained at 30 degrees C whereas the longest mean generation time (T=28.39 day) was observed at 20 degrees C. Ou r results revealed that 25 degrees C was more suitable for mass production even if the female and male of T. athiasae survived and reproduced at all temperatures. Consequently, our present results and the data to be obtained in greenhouse and field conditions will reveal the potential of T. athiasae as a biological control agent of T. urticae.

    Population development of European red mite Panonychus ulmi (Koch) (Acari: Tetranychidae) on apple orchards in Çanakkale, Turkey
    (2019) Kasap, İsmail; Kök, Şahin; Pehlivan, Serkan; Baştuğ, Gökhan
    The aim of thisstudy was to determine the seasonal population dynamics of the European red mite, Panonychus ulmi (Koch)(Acari: Tetranychidae) on different apple varieties in apple orchards inÇanakkale, Turkey, during 2010-2011. Surveyswere carried out weekly from April to November in sprayed and unsprayedorchards on cultivated GoldenDelicious, Starking Delicious and Grany Smith apple varieties. The results ofthe study indicated that the population density of spider mites began toincrease generally in early May, and reached the maximum level from mid June tolate August. Afterwards, it preserved to late September in both years. Duringthe both years, P. ulmi more preferedthe Starking Delicious than Golden Delicious and Grany Smith apple varieties inthe all orchards. In this period, the population densitiy of P. ulmi reached to maximum level with 115.9 and 75.3 mites/per leaf on theStarking Delicious apple variety in 2010 and 2011 years, respectively insprayed orchards. In unsprayed orchard, spider mites remained at very low levels certainly because of thepresence of Typhlodromus athiasae Porath and Swirski (Acari:Phytoseiidae) which was only one predator species on spider mites. On the otherhand in sprayed orchards, although Stethoruspunctillum (Col.: Coccinellidae) and Zetzellia mali (Acari: Stigmaeidae) were the most abundant predatory specieson spider mites, they could notcontrol the spider mites on bothapple cultivar and years.
