Öğe Distribution of Steinernematids and Heterorhabditids (Rhabditida: Steinernematidae and Heterorhabditidae) in the Southern Anatolia Region of Turkey(EGYPTIAN SOC BIOLOGICAL CONTROL PESTS, 2016) Canhilal, R.; Waeyenberge, L.; Toktay, H.; Bozbuga, R.; Cerintas, R.; Imren, M.This study was conducted to isolate and identify entomopathogenic nematode (EPN) species in different agricultural areas in the Southern Anatolia region of Turkey. Out of 193 soil samples, 20 (10.33%) turned out to be positive for the presence of EPNs, belonging to the genera Steinernema and Heterorhabditis. Morphological and molecular (ITS-RDNA) characterizations were performed for the 20 EPN isolates. Six isolates were identified as H. bacteriophora, 2 as H indica and 6 as S. feltiae. Two isolates were undescribed Steinernemas pecies. H. indica was recorded for the first time in the southern Anatolia region of Turkey. Molecular analysis confirmed the morphological identification of Heterorhabditidae and Steinernematidae species. Comparative analysis of the ITS sequences revealed interspecific polymorphism among the tested isolates. Additionally, intraspecific polymorphism was observed within S. feltiaeand H bacteriophorapopulations, but no intraspecific polymorphism was detected in the H indicapopulation.Öğe Effects of Some Indigenous Plant Extracts on Mortality of the Root Lesion Nematode, Pratylenchus thornei Sher & Allen(EGYPTIAN SOC BIOLOGICAL CONTROL PESTS, 2016) Kepenekci, I.; Toktay, H.; Saglam, H. D.; Erdogus, D.; Imren, M.The genus of root lesion nematodes (RLN), Pratylenchus, feeds and reproduces in the root cortex of many plant species. RLN was reproduced on carrot culture by using a pure culture. In vitro tests were carried out to determine the effects of plant extracts from three indigenous plants: henbane, Hyoscyamus niger; bead-tree, Melia azedarah and common cocklebur, Xanthium strumarium on P. thornei (the major wheat root-lesion nematode). The nematodes were exposed for 12, 24, 48, 72 and 96 hrs in three concentrations of plant extracts. The effect of plant extracts was performed using the suspensions of P. thornei (100 nematodes ml(-1)) in distilled water. Distilled water was used as a control. All dishes were kept at 28 +/- 2 degrees C. The plant extracts of H. niger, M. azedarah and X strumarium exhibited highly promising mortality rate (100%) after 72 hours of exposure time. The result of this study suggests the studied plant extracts to be used for reducing the P. thornei population.Öğe MOLECULAR CHARACTERIZATION OF HETERODERA SPP AND PRATYLENCHUS SPP.
