The Genus Helicotylenchus Steiner, 1945 in West Malaysia

Nematologica, 1975
Species of Helicotylenchus are common in the soils of West Malaysia, both cultivated and uncultivated. The most widely distributed species are H. dihystera (Cobb) and H. multicinctus (Cobb). H. pseudorobustus (Steiner), H. abunaamai Siddiqi, and H. crenacauda Sher, have also been identified from cultivated soils. H.

Mechanism of Locomotion in Hoplolaimus Indicus and Helicotylenchus Indicus

Nematologica, 1976
The locomotory behaviour of adults and juveniles of Hoplolaimus indicus and Helicotylenchus indicus was studied in the presence of the host (directional stimulus). The movement of the two species of nematodes accelerates as they approached the host. The behavioural mechanism responses by which they increase their velocity differed.

Morphological and molecular characterization of three Helicotylenchus species from Iran

Zootaxa, 2018
Three Helicotylenchus species, namely Helicotylenchus digonicus, Helicotylenchus pseudorobustus and Helicotylenchus vulgaris were identified during a nematode survey conducted in Iran. The morphological and molecular characteristics of the species were defined.

Description of Helicotylenchus persiaensis sp. n. (Nematoda: Hoplolaimidae) from Iran 

Zootaxa, 2014
In order to identify the species of Helicotylenchus Steiner, 1945 present in Iran, 497 soil and root samples were collected from the rhizosphere of different plants and localities throughout the country during 2009-2010. A new and several known species of Helicotylenchus were identified from the collected material. H. persiaensis sp. n.

Cytology and Reproduction of Helicotylenchus Dihystera and H. Erythrinae 1)

Nematologica, 1967
Several populations of the monosexual species Helscotylenchus dihystera were studied with respect to their chromosomal complement and mode of reproduction to clarify the question of digonic hermaphroditism. No synapsis of homologous chromosomes takes place and maturation consists of a single mitotic division.

Helicotylenchus dihysterain Australian cotton roots

Australasian Plant Pathology, 2006
We report for the first time in Australia, observation of the plant-parasitic nematode Helicotylenchus dihystera within roots of cotton (Gossipium hirsutum). The incidence of this and other nematodes in cotton roots did not correlate with the incidence of Verticillium wilt that was present within the same crops.

The Feeding Behaviour of Helicotylenchus Spp. On Wheat Roots

Nematologica, 1978
H. dihystera and H. varicaudatus feed as sedentary parasites. Typically, several cells are penetrated before feeding begins. Cell walls are ruptured by the combination of forward body pressure and piercing the walls by the stylet. After penetration, feeding from a single cell continues for several days, with alternating salivation and ingestion. During
