Rotylenchus castilloi n. sp., a new bisexual species is described and illustrated based on morphological, morphometric and molecular data. The new species is characterised by having a hemispherical, continuous lip region with an irregular corncob-like appearance under SEM, very long stylet (62-68 µm), vulva located at 49.7-62.2% of body length from anterior end, with a protruding double epiptyg...

DNA sequences of the D2-D3 expansion segments of the 28S gene of ribosomal DNA from 23 taxa of the subfamily Hoplolaiminae were obtained and aligned to infer phylogenetic relationships. The D2 and D3 expansion regions are G-C rich (59.2%), with up to 20.7% genetic divergence between Scutellonema brachyurum and Hoplolaimus concaudajuvencus. Molecular phylogenetic analysis using maximum likelihoo...

Soil nematode feeding groups are a long-established trophic categorisation largely based on morphology and are used in ecological indices to monitor and analyse the biological state of soils. Stable isotope ratio analysis ((13)C/(12)C and (15)N/(14)N, expressed as δ (13)C and δ (15)N) has provided verification of, and novel insights into, the feeding ecology of soil animals such as earthworms a...

Bitki paraziti nematodlar kültür bitkilerinde ekonomik kayıplara neden olan zararlı organizmalardır. Bu çalışma Kırgızistan’ın kuzeyinde yer alan Talas ve Tokmok Bölgeleri patates ekiliş alanlarında bulunan bitki nematod türlerini saptamak amacıyla yürütülmüştür. amaçla 2016 yılı yaz aylarında yapılan survey çalışmalarında alanlarından 15 adet toprak örneği alınmıştır. Örneklerden elde edilen t...

Summary Rotylenchus bunae n. sp. was discovered in the coffee rhizosphere Gera district of Jimma, Ethiopia, and has been morphologically molecularly characterised. The new species is identified by a female body length 725-876 μ m, hemispherical lip region with 4-5 annuli, stylet 28-30 lateral field areolation only pharyngeal region, no cuticular striations, gland overlapping intestine dorsally ...
