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.

These findings agreed with the original and previous descriptions of this nematode species Siddiqi, In Greece, both species have been previously reported but no morphometrics or molecular data were available for these species.

Lip region hemispherical, slightly offset, with usually 4 annules and mu,ticinctus prominent oral depression terminally; framework heavily sclerotized, with conspicuous outer margins extending posteriorly through 3 to 4 body annules, which are much narrower at that region than at others.

Plant-parasitic nematodes associated with bananas and plantains in Southern Florida. Michel Luc; Richard A. Males are shorter and thinner than females.
Excretory pore at level of heljcotylenchus junction; hemizonid body annules anterior to it. However, morphometric characteristic or molecular data of the nematode were not provided.

These findings confirm the identity of the species and the intraspecific variability yelicotylenchus several populations with different geographic origin and were within the range of the original description Mali and Hooper, and other reported populations Guesmi-Mzoughi et al.
Chemical Control Due to the variable regulations around de- registration of pesticides, we are for the moment not including any specific chemical control recommendations. Their data are the most reliable because the spiral nematode occurred in the absence of Radopholus similis and Pratylenchus coffeae, the other two major pests of banana.
