Coprosma macrocarpa, known as the large-seeded coprosma or coastal karamu, is a shrub endemic to New Zealand. To our knowledge, no reports of plant parasitic nematodes associated with C. macrocarpa have been reported. Here we report the detection and identification of the nematode, Litylenchus coprosma, extracted from C. macrocarpa in Otata Island.

Plant Parasitic

A computerbased key for identifying plant parasitic nematodes of temperate agriculture in New Zealand and around the world is described It uses the Lucid software developed at the University of Queensland and includes images of major diagnostic features The key is multiaccess rather than dichotomous so may be entered at any point allowing for the most obvious characters of a specimen to be scored first and thereby immediately reduce the number of likely taxa Both qualitative and quantitative characters are used The key requires that the specimen can be viewed microscopically but examples of most morphological terms are illustrated so the nonspecialist should be able to make use of the key

Abstract This volume compiles and updates information on invasive plant-parasitic nematodes and their looming threat in different countries. It offers a global perspective on invasive nematodes by presenting 17 chapters with information on more than 100 nematodes and their potential threat in different countries. Each nematode entry includes information on: authentic identification; geographical distribution; risk of introduction; host ranges; symptoms; biology and ecology; planting material liable to carry the nematode(s) and its vector, if any; chance of establishment; likely impact; phytosanitary measures; and a detailed account of diagnosis procedures, such as sampling, isolation/detection and identification with morphological and molecular characterization. The aim of the book is to provide basic and advanced knowledge on invasive nematodes with a global perspective, and it targets practitioners, professionals, scientists, researchers, students and government officials working on plant quarantine and biosecurity with regard to plant-parasitic nematodes.

Meloidogyne Sp

The endoparasite of several phytonematodes, Pasteuria penetrans, was found to parasitize juveniles and males of a Meloidogyne sp. in Portugal and juveniles of Heterodera fici in Italy. The infectivity on Meloidogyne males and H. fici juveniles is illustrated with light, scanning, and transmission electron microscopy. The great number of spores found attached on both genera characterizes these nematodes as potential hosts, and establishes a new host and distribution record for this antagonist of plant-parasitic nematodes.

Morphology and symptoms of Ditylenchus dryadis n.sp., a bisexual leaf galling parasite that is similar taxonomically to D. dipsaci and pathogenically to the Anguininae, are described and illustrated. The main differentiating characters for the female are its large, distended postuterine sac, which occupies 75% of the vulva–anus distance and the quadricolumellate crustaformaria; and, for both sexes, six to eight incisures, presence of a conspicuous deirid, a basal esophageal bulb of three cells that does not overlap the intestine, and an acute tail terminus. Disease symptoms are galls of various configurations on the leaves only of Dryas integrifolia M. Vahl, ecologically the most important of the vascular plants from the type locality and a new host record for plant parasitic nematodes. Galls examined on dried leaves were typically red, had diameters of up to 5 mm, and contained from 2 to 60 nematodes with numerous eggs.
