A survey of plant parasitic nematodes associated with chickpea was conducted in the chickpea growing areas of Turkey including 37 districts in 17 provinces during spring and summer of 2014-2016. A total of 211 soil and root samples were collected. Nematodes were extracted from soil by different extraction methods to ensure all kinds of nematode groups. Nematodes were identified using morphological and morphometric features. In addition, Pratylenchus spp. Filipjev, 1936 were determined using species-specific primers. Ditylenchus dipsaci (Kühn, 1857), Pratylenchus neglectus (Rensch, 1924) and Pratylenchus thornei Sher & Allen, 1953 were the most common of the plant parasitic nematodes associated with chickpea in the areas surveyed.
Chaff scale, Parlatoria pergandii Comstock (Hemiptera:Diaspididae) causes damages by sucking trunk, branches, leaves and fruits of its hosts. It causes characteristic green spotting on fruits decreasing its market value, desiccate of leaves and branches and drop of the fruits at high infestations. This study was implemented to detect the parasitoid and predator species of P. pergandii at citrus plantations in eastern Mediterranean region (Adana, Hatay, Mersin and Osmaniye) in 2012-2013. Culturing of shoots and fruits for detecting parasitoids and visual control and strike methods for detecting the predators were applied. As the result of the study, it was detected that Chilocorus bipustulatus (L.) (Coleoptera:Coccinellidae) was the most prevalent and dominant predator of P. pergandii and being detected at all the areas surveyed. The relative abundance was 39.84% and 44.36% in 2012 and 2013, respectively. This species was followed by Rhyzobius lophanthae Blaisdell (Coleoptera:Coccinellidae) and Cybocephalus fodori minor (E.Y.) (Coleoptera:Cybocephalidae). The abundance of Aphytis melinus DeBach (Hymenoptera:Aphelinidae), the dominant parasitoid species, was 43.80% and 47.10% in 2012 and 2013, respectively.
Pyralidae)]'nin ergin popülasyon değişimi, mücadelesi ve zarar oranının belirlenmesi amaçlanmıştır. Zararlının popülasyon değişimi eşeysel çekici tuzaklar ile izlenirken mücadelesi biyolojik insektisit ile gerçekleştirilmiştir. C. gnidiella erginlerinin tuzaklarda ilk olarak nisan ayında yakalandığı belirlenmiştir. Vejetasyon başlangıcında düşük olan zararlı popülasyonunun, temmuz ayı ortasından itibaren artış gösterdiği ve ekim-kasım aylarında en yüksek popülasyonda olduğu saptanmıştır. C. gnidiella'nın Trabzon hurması bahçesinde yılda 5 döl verdiği tespit edilmiştir. Mücadelede kullanılan Bacillus thuringiensis preparatı, C. gnidilella'ya 2012 ve 2013 yıllarında sırasıyla ortalama %88.99 ve %90.84 oranlarında etkili olmuştur. Adana'nın farklı ilçelerindeki Trabzon hurması bahçelerinde C. gnidiella ile bulaşık meyve oranı %3.1-26.7 arasında bulunmuştur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
