Sununary - Morphologlcal characters and randomly amplified polymorphie DNA (RAPD) fragments were used for phylogenetic analysis in entomopathogenic nematodes of the genus Sleinernema. The phylogenetic relationships of Sleinemema species based on different suites of data were not congruent. We found that RAPD fragments were an effective means of differentiating species, but the divergence among species at this level was so great that these fragments may provide little information about the…

Phylogenetic relationships of Steinernema Travassos, 1927 (Nematoda: Cephalobina: Steinernematidae) based on nuclear, mitochondrial and morphological data
TLDR
Parsimony mapping of morphological characters on the 3-gene trees showed that most structural features of steinernematids are highly homoplastic, and the distribution of nematode foraging strategies on these trees predicts that S. hermaphroditum, S. diaprepesi and S. longicaudum have cruise forager behaviours.
Phylogeny of Steinernema Travassos, 1927 (Cephalobina: Steinernematidae) Inferred From Ribosomal DNA Sequences and Morphological Characters
TLDR
Interpretation of morphological character evolution on 6 trees inferred from sequence data and combined evidence suggests that many structural features of these nematodes are highly homoplastic, and that some structures previously used to hypothesize relationships represent ancestral character states.
Phylogenetic relationships of entomopathogenic nematodes (Heterorhabditidae and Steinernematidae) inferred from partial 18S rRNA gene sequences.
TLDR
It is suggested that the partial 18S rRNA gene sequences may be too conserved for phylogenetic inference among Heterorhabditis species, but are well suited for phylogenetics inference within and among closely related families and genera of entomopathogenic nematodes.
Phylogenetic relationships within the genus Steinernema (Nematoda: Rhabditida) as inferred from analyses of sequences of the ITS1-5.8S-ITS2 region of rDNA and morphological features
TLDR
The ITS rDNA data were found to be of little utility in resolving relationships between these clades, but were useful in studying relationships between species within certain clades.
Phylogenetic Analysis of rDNA Sequences from Adenophorean Nematodes and Implications for the Adenophorea-Secernentea Controversy
Phylogenetic relationships of 13 adenophorean and 15 secementean nematodes were analyzed using morphological data and 18S rDNA sequences in parallel. Both data sets strongly supported monophyly of
GENETIC VARIATION AND RELATIONSHIPS BETWEEN ISOLATES AND SPECIES OF THE ENTOMOPATHOGENIC NEMATODE GENUS HETERORHABDITIS DECIPHERED THROUGH ISOZYME PROFILES
TLDR
Pairwise distance analysis revealed that genetic divergence among populations of H. bacteriophora is relatively independent of geographic distance, and trees constructed using different phylogenetic methods showed a relatively close genetic relationship between H. megidis and H. zealandica.
Molecular characterisation of novel isolates of entomopathogenic nematodes
TLDR
The BLAST analysis of the ITS region of the rDNA of the steinernematid isolate PAL10 showed a rather low similarity of 93% with S. vulcanicum, supporting the possible designation of a new species, but the description of the new species would need further morphometric characterisation, morphologically identification and cross-breeding studies.
Intraspecific variation among isolates of the entomopathogenic nematode Steinernema feltiae from Bull Island, Ireland
TLDR
Assessment of the fitness, with regards to fecundity, host insect mortality and time taken to produce progeny, of isolates of Steinernema feltiae from Bull Island, Ireland finds that following the crossbreeding of all isolates in Galleria mellonella, the number of host cadavers exhibiting emerging infective juveniles was significantly fewer than expected and there were significant differences between isolate in the numbers of days until progeny were observed.
Steinernema citrae n. sp. (Rhabditida: Steinernematidae), a new entomopathogenic nematode from South Africa
During a survey for entomopathogenic nematodes in citrus orchards throughout South Africa, a new species of Steinernema was isolated from a citrus orchard on Rietkloof farm, near the town of
Heat Shock Protein Hsp70 Multigene Family as a New Genetic Target for The Differentiation and Identification of Entomopathogenic Nematodes (Rhabditida: Heterorhabditidae)
TLDR
This is the first study to use hsp70 multigene family as a target to differentiate entomopathogenic nematode species, and the amplified intron regions exhibited distinct and reproducible patterns that characterized the different species of Heterorhabditis.

Differentiation of isolates in the genus Steinernema (Nematoda: Steinernematidae).by random amplified polymorphic DNA fragments and morphological characters
TLDR
This study combined polymerase chain reaction (PCR) amplification of DNA sequences and important morphological characters as a technique to differentiate nematode isolates in the genus Steinernema, and identified isolate OH1S, collected from Newport, Oregon, as S. feltiae ; isolate OS21, Collected from Grants Pass,Oregon, belonged to a previously undescribed species.

Characterization of random amplified polymorphic DNA (RAPD) products from Xanthomonas campestris and some comments on the use of RAPD products in phylogenetic analysis.
TLDR
The use of the random amplified polymorphic DNA (RAPD) technique is examined to determine if a valid cladistic character analysis could be carried out by direct comparison of RAPD products separated on ethidium bromide-stained agarose gels, and absence phenotypes arising from the apparent absence of corresponding loci are demonstrated.

THE USEFULNESS OF BEHAVIOR FOR PHYLOGENY ESTIMATION: LEVELS OF HOMOPLASY IN BEHAVIORAL AND MORPHOLOGICAL CHARACTERS
TLDR
This work compared levels of homoplasy for morphological and behavioral characters that have been used in systematic studies to support the idea that behavioral characters are less useful than morphological characters for the estimation of phylogeny.
Neoaplectana glaseri and N. anomali : sibling species or parallelism?
TLDR
A comparison was made between Neoaplectana glaseri which occurs in North and South America and N. anomali which has been reported only from Central Europe and whether these two species are an example of parallelism or divergence is addressed.
