Lists nematode genera (and the number of species in each) collected on the Canadian Arctic Expedition in 1915-1916, and at Lake Hazen, Ellesmere Island, in 1962. The former collection, identified by N.A. Cobb, but not hitherto reported (cf. No. 2817 pt. F), comprises 22 genera containing 47 species, about half of which are cosmopolitan. The Lake Hazen collection is the first the the High Arctic; it contains at least 30 described and several undescribed genera, comprising 60 or more species. Gen. Plectus is abundant in both collections.

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.

Plant Parasitic

Plant parasitic nematodes are annually responsible for the loss of 10%–25% of worldwide crop production, most of which is attributable to root-knot nematodes (RKNs) that infest a wide range of agricultural crops throughout the world. Current nematode control tools are not enough to ensure the effective management of these parasites, mainly due to the severe restrictions imposed on the use of chemical pesticides. Therefore, it is important to discover new potential nematicidal sources that are suitable for the development of additional safe and effective control strategies. In the last few decades, there has been an explosion of information about the use of seaweeds as plant growth stimulants and potential nematicides. Novel bioactive compounds have been isolated from marine cyanobacteria and sponges in an effort to find their application outside marine ecosystems and in the discovery of new drugs. Their potential as antihelmintics could also be exploited to find applicability against plant parasitic nematodes. The present review focuses on the activity of marine organisms on RKNs and their potential application as safe nematicidal agents.
