    First report of sugar beet nematode, Heterodera schachtii Schmidt, 1871 (Nemata: Heteroderidae) in sugar beet growing areas of Sanliurfa, Turkey
    (Türkiye Entomoloji Derneği, 2016) Jiang-Kuan Cui; Erginbas Orakci, G.; Huan Peng; Wen-Kun Huang; Shiming Liu; Fen Qiao; Elekcioglu, I.H.; Imren, M.; Dababat, A.A.; De-Liang Peng
    The sugar beet nematode, Heterodera schachtii, is the major pest of sugar beet and causes serious yield losses of about 10-70%. Heterodera schachtii occurs in more than 50 countries and regions, however, there has be limited investigation of H. schachtii in Turkey. Therefore, a survey of H. schachtii in the sugar beet producing regions of Şanlıurfa was conducted in 2014 and 2015 growing seasons. Using morphological and molecular methods, 12 samples collected from three districts, Bozova, Karaköprü and Siverek, in Şanlıurfa Province, Turkey, were identified as H. schachtii. In pathogenicity test, the seedling emergence was delayed and reduced, the seedlings were stunted and necrotic, and the white females of H. schachtii were evident 25 days after inoculation. Phylogenetic analyses were also conducted. The 12 H. schachtii populations from Şanlıurfa Province clustered together with populations from Europe and Morocco at the value of 99%. Sugar beet is the second largest crop in Turkey with the annual production of more 16 Mt. To our best knowledge, this is the first report of H. schachtii in Şanlıurfa Province of Turkey.

    Pathotype characterization of the cereal cyst nematode Heterodera filipjevi (Madzhidov, 1981) Stelter in Turkey
    (Entomological Society Turkey, Ege University, 2013) Toktay, H.; Imren, M.; Bozbuga, R.; Erginbas Orakci, G.; Dababat, A.A.; Elekcioglu, I.H.
    Turkey is ranked among top ten wheat producing countries in the world. Cereal cyst nematodes are considered one of the most damaging plant parasitic nematodes on wheat worldwide. Up to date, the most effective method of controlling this group of nematodes is the use of crop rotation and resistant varieties. The successful development of disease-resistant plants is contingent on knowledge of the pathotypes of the causal agent. In this study, three populations of Heterodera filipjevi (Madzhidov, 1981) Stelter were collected from different locations (Afsin, Elbistan and Yozgat) in Turkey in order to identify their pathotype using ?The International Test Assortment of Cereal Cultivars?. The results showed that two populations gave a similar reaction to the resistant and susceptible varieties. These populations were determined as Ha 33 pathotype which is a new report for Turkey.
