Morphological and molecular variations within Helicotylenchus vulgaris
Biologia, 2020Helicotylenchus vulgaris is a plant-parasitic nematode reported from several countries in various biogeographical regions. During the survey on Helicotylenchus in Iran and the South African Plant-Parasitic Nematode Survey in South Africa, H. vulgaris was found in samples from northern and southern Iran and from two provinces in South Africa ...

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.

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.

Cytology and Reproduction of Helicotylenchus Dihystera and H. Erythrinae 1)
Nematologica, 1967Several 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.

The Feeding Behaviour of Helicotylenchus Spp. On Wheat Roots
Nematologica, 1978H. 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
