Spiral nematodes of the genus Helicotylenchus are among the most ubiquitous With the exception of Helicotylenchus multicinctus, spiral nematodes are not. The damage symptoms are similar to those caused by other serious root endoparasites of the family Pratylenchidae, both on banana plants and plantains. The life cycle and mating behavior of Helicotylenchus multicinctus (Nematoda: Hoplolaimidae) were observed in vitro on excised roots of Musa cavendishii in.

Pinochet J; Ventura O, Adult males and females reproduce sexually by amphimixis. The common name spiral nematode is most often applied to nematodes in the genus Helicotylenchushepicotylenchus it is also sometimes applied to other genera in the family Hoplolaimidae, including RotylenchusAorolaimusScutellonemaand Peltamigratus.
Living specimens can be extracted from viable root multicinctsu, either under a dissecting microscope or by following the extraction procedures illustrated in general nematology handbooks. Females lay eggs individually in soil.
Management Back to Top The extensive host range of Helicotylenchus spp. Genital apparatus composed of two symmetrical ovaries; sometimes the posterior ovary may appear reduced, but is still functional.
The presence of males is a useful biological character to separate Helicotylenchus multicinctus from species that do not have males. For both species, morphometrics and molecular data of Greek populations were provided, resulting in the first integrative identification of both nematode species based on morphometric and molecular markers, confirming the occurrence of these two nematodes in Greece as had been stated in earlier reports.
Plant pests of quarantine importance to the Caribbean. Thus it is regarded as an endoparasite, although there is no evidence of nematode migration through the cortical tissues Blake, In Cuba, the nematode was detected in 32 host plants, including beets, common beans, carrots, cowpeas, garlic, hairy cotton, head cabbages, lettuces, melons, peas, rape and watermelons Stoyanov, Groups of eggs, orientated parallel to the long cell axes, were frequently observed in discoloured cortical tissues.
