Helicotylenchus dihysterain Australian cotton roots
Australasian Plant Pathology, 2006We 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 Genus Helicotylenchus Steiner, 1945 in West Malaysia
Nematologica, 1975Species 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.

Description of Helicotylenchus persiaensis sp. n. (Nematoda: Hoplolaimidae) from Iran
Zootaxa, 2014In 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.

Mechanism of Locomotion in Hoplolaimus Indicus and Helicotylenchus Indicus
Nematologica, 1976The 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.
