LONGIDORUS ELONGATUS PDF

Common needle nematode 2. Geographical distribution Longidorus Elongatus is a common nematode in many parts of the world. Biological characteristics Longidorus sp. Males are usually rare and reproduction is apparently parthenogenetic, although bisexual reproduction is possible in populations were males are common. Longidorus elongates have four juvenile stages and overwinter as juveniles and adults in the soil.

Longidorus Elongatus

The nematode species was detected in turf Poa sp. Prior to this find, L. The current temporary Q-rating of the nematode species is reassessed here and a permanent rating is proposed. Longidorus elongatus has four juvenile stages and most likely produces one generation a year especially under field conditions however, there is a two- to four-fold increase on favored hosts. The nematode species is found in cool soils that may vary from peat to sandy loams, although the species appears to prefer coarse, well-drained soils. Adults may live for several years, and the time to complete its life cycle is dependent on soil temperature. Males are rare and reproduction is usually by parthenogenesis, except where males are common, in which case bisexual reproduction occurs.

Photographs from Griffiths and Robertson The nematodes tend to accumulate around and just behind the root tips where they feed ectoparasitically resulting in swelling and galling of the root tip and a general stunting of the root system. Economic impact The ectoparasitic pathogen manifest only in the field on the roots of onions. By microscopic monitoring, the characteristics of pathogen are clearly different from D.
