Yeşilkurt (Helicoverpa armigera Hübner) domates yetiştiriciliğinde verim ve kaliteyi olumsuz yönde etkileyen polifag bir zararlı olup, son yıllarda popülasyon yoğunluğunda görülen artış ile zararlı türler arasındaki önemi artmıştır. Bu çalışmada 2013 ve 2014 yıllarında Diyarbakır ili Merkez, Çınar, Ergani ve Bismil ilçelerinde Yeşilkurt’un popülasyon takibi yapılmıştır. Her lokasyonda araziyi temsil edecek şekilde tesadüfi olarak seçilen bitkilerde fide döneminden başlamak üzere hasada kadar, zararlının ergin ve ergin öncesi dönemleri haftalık takip edilmiştir. Zararlının ergin öncesi döneminde en fazla bulaşıklık eylül, ekim aylarında %80 ile Merkez ve Ergani’de ergin dönemde ise en fazla ağustos ayında 237 ergin/tuzak ile Bismil ilçesinde belirlenmiştir. H. armigera’nın larva parazitoitleri Apanteles sp., Habrobracon sp., Campoletis sp., Hyposoter sp., olarak belirlenmiştir. Larvaların ilk yıl parazitlenme oranı %2.04 iken ikinci yıl ise %1.53 olarak tespit edilmiştir. Zararlının predatörleri Deraeocoris pallens (Reuter, 1904), Macrolophus pygmaeus (Rambur, 1839), Geocoris pallidipennis (A. Costa, 1843), G. megacephalus (Rossi, 1790), Nabis pseudoferus (Remane, 1949), Orius niger (Wolff, 1811), O. albidipennis (Reuter), Chrysoperla carnea (Stephens, 1836), Adonia variegata (Goeze, 1777), Coccinella septempunctata (Linnaeus, 1758) ve Scymnus levaillanti (Mulsant, 1850) olarak bulunmuştur. Çalışma sonucunda, Diyarbakır ilinde H. armigera’nın bulaşıklık ve popülasyon yoğunluğuna ilaçlama ve doğal düşmanların etkinliğinin yanı sıra iklim koşullarının da etkisi olabileceği değerlendirilmektedir.
Green Curtis (Helicoverpa armigera Hübner) is a polifag that affects productivity and quality in tomato cultivation and has increased its importance between the increase in population intensity and the harmful species in recent years. In this study, in 2013 and 2014 the population tracking of Greşilkurt was carried out in the districts of Diyarbakır or Central, Chinar, Ergani and Bismil. In the plants randomly selected to represent the soil in each location, from the fide period to the harvest, the periods of damages before the adult and the adult were followed weekly. The highest infection in the pre-adolescent period was determined in September, in October with 80% in Central and Ergani; in the adult period, the highest in August with 237 adult/touch in the Bismil district. by H. The larva parasites of armigera are identified as Apanteles sp., Habrobracon sp., Campoletis sp., Hyposoter sp. In the first year, the parasitization rate of the larva was 2.04%, while in the second year it was 1.53%. Deraeocoris pallens (Reuter, 1904), Macrolophus pygmaeus (Rambur, 1839), Geocoris pallidipennis (A. Costa, 1843), G. megacephalus (Rossi, 1790), Nabis pseudoferus (Remane, 1949), Orius niger (Wolff, 1811), O. albidipennis (Reuter), Chrysoperla carnea (Stephens, 1836), Adonia variegata (Goeze, 1777), Coccinella septempunctata (Linnaeus, 1758) and Scymnus levaillanti (Mulsant, 1850). The work was done in the H. It is estimated that armigera may have an impact on the infectiousness and population intensity and the effectiveness of natural enemies as well as climate conditions.
Tomato fruit borer (Helicoverpa armigera Hübner) is a polyphagous pest that negatively affects yield and quality in tomato cultivation, and its importance has increased between the harmful species with the increase in population density in recent years. In this study, population monitoring of tomato fruit borer was carried out in the Central, Çınar, Ergani, and Bismil districts of Diyarbakır province in 2013 and 2014. The plants were randomly selected to represent the field at each location, starting from the seedling period to harvest until the adult and immature stages of pests were followed weekly. The highest infestation rates of immature stages were determined at Central and Ergani districts in September and October as 80%, while the highest numbers of adults were caught in Bismil district in August as 237 individuals/trap. Apanteles sp., Habrobracon sp., Campoletis sp., and Hyposoter sp. were found as larvae parasitoids of H. armigera. The parasitization rate of larvae was determined as 2.04% in the first year, while it was found as 1.53% in the second year. Species such as Deraeocoris pallens (Reuter, 1904), Macrolophus pygmaeus (Rambur, 1839), Geocoris pallidipennis (A. Costa, 1843), G. megacephalus (Rossi, 1790), Nabis pseudoferus (Remane, 1949), Orius niger (Wolff, 1811), O. albidipennis (Reuter), Chrysoperla carnea (Stephens, 1836), Adonia variegata (Goeze, 1777), Coccinella septempunctata (Linnaeus, 1758) and Scymnus levaillanti (Mulsant, 1850) were determined as predators of the pest. According to the findings of this study, infestation and population density of H. armigera may be affected due to chemical applications and natural enemies as well as climatic conditions in Diyarbakır province.
