Characterization of Juvenile Stages of Bursaphelenchus crenati Rühm, 1956 (Nematoda: Aphelenchoidoidea)

In this study juvenile stages of Bursaphelenchus crenati (Sexdentati group) were distinguished based mainly on the genital primordium structure. Dauer stage juveniles were sampled under elytra of Hylesinus crenatus in galleries in bark of the wilted Fraxinus excelsior in the Voronezh region of Russia and were multiplied in laboratory cultures on the fungus Botrytis cinerea. Individual development included five stages (J1-J4 and adults) separated by molts. The first molt J1 to J2 occurred inside

Integrative taxonomy of Xiphinema histriae and Xiphinema lapidosum from Spain

population of Xiphinema lapidosum was identified in association with Olea europaea subsp. europaea L. Lamberti et al. (1993a, 1993b) and Roca and Bravo (1993) described female and male stages of X. histriae and X. lapidosum, respectively, but in both species no juvenile stages were detected and described. The objectives of this study were: (i) to provide updated morphological descriptions of juvenile stages of X. histriae and X. lapidosum, (ii) to characterize the molecular data of both species using the

Description of Xiphinema parachambersi sp. n. (Nematoda: Longidoridae) from Imported Ornamental Plants in Japan with a Key to Xiphinema Species in Group 1

rounded terminus. Only two juvenile stages were available to study and no male was found. The polytomous identification codes for this new species are A1, B4, C2, D23, E1, F2, G2, H2, I2, J2, K?, L1 and it belongs to the morphospecies group 1. Phylogenetic analysis based on the 18S, ITS1 and 28S D2/D3 sequences of the new species showed close relationships with X. chambersi. Morphologically, the new species is similar to X. chambersi, X. hangzhouense, and X. winotoi but can be differentiated by

Description of a new dagger nematode, Xiphinema barooghii n. sp. (Nematoda: Longidoridae) and additional data on the three known species of the genus from northwest of Iran

, conoid and dorsally convex, ventrally directed with a small terminal peg, 4.5‒7.5 μm long, and a distinct terminal blind canal, exists. Three to four caudal pores are present on each side. Male Not found. Juveniles All four juvenile stages were identified using morphological characters such as body length, length of replacement and functional odontostyle (Robbins et al., 1996). The scatter diagram representing the relationships between body length, functional and replacement odontostyle of
