Abstract

Longidorus caespiticola was found for the first time from the rhizosphere of apple with two other Longidorus sp. at Žlunice, Czech Republic. Females and males were analyzed morphologically and morphometrically. Four regions (18S, ITS1, ITS2, D2-D3 expansion segments of 28S) of ribosomal DNA and one region (cox1) of mitochondrial DNA were sequenced and analyzed and compared with a population from the Slovak Republic. The partial mitochondrial cytochrome c oxidase subunit 1 (cox1) gene showed relatively high genetic variation compared with ribosomal DNA between the Czech and Slovakian populations.

Abstract

Soil samples under the rhizosphere of Brasicca napus were collected from three localities (Bílé Podolí, Prague, Kylešovice). Two localities Prague and Kylešovice were positive for the presence of Pratylenchus neglectus. The species was identified using morphological features and the morphological identification was verified by using published species-specific primers and by sequencing 18S and 28S genes of ribosomal DNA.

Abstract

Soil samples under the rhizosphere of Brasicca napus were collected from three localities (Bílé Podolí, Prague, Kylešovice). All three localities were positive for the presence of Aphelenchus avenae. Morphological and molecular features of A. avenae are presented in this research note.

Abstract

The distribution of Pratylenchus species associated with wheat crops was investigated in Bohemian region of the Czech Republic. In total twelve localities were sampled. The populations were identified based on morphology and morphometrics, and further characterised based on sequences of the rDNA D2/D3 region and 18S gene. Pratylenchus crenatus was present in two localities and P. neglectus in five localities. At one locality both species were detected. Sequence analysis of 18S and D2/D3 region of three populations of P. crenatus reveal no variation while five populations of P. neglectus differ by 0 to 0.14 % (18S) and 0.17 to 0.50 % (D2/D3).

Abstract

Morphological Redescription and Molecular Characterization of Dactylogyrus labei (Monogenea, Dactylogyridae) from Catla catla: a New Host Record in India. Chiary, H. R., Chaudhary, A., Singh, H. S. - Dactylogyrus labei Musselius et Gusev, 1976 (atypical form) specimens were collected from host Catla catla from the river Brahmaputra, Guwahati, Assam, India. The Dactylogyrus samples were examined by morphological and molecular methods. This parasite was originally described from Labeo rohita from fish farm Kalyani, West Bengal, India, but the morphological study of sclerotized parts showed the existence of D. labei on Catla catla. This is the first record of D. labei from Catla catla in India.
