During July, 1943, a number of wild and cultivated plants in the Blackwell district, near Sarnia, Ontario, were examined for parasitic nematodes. Wild host-plants of the sugar-beet nematode, Heterodera schachtii Schm., recorded in a note in the Canadian Entomologist of October, 1941, were again noted, and one new host record was obtained for this nematode in Canada.

The sudden occurrence of severe attacks of A. dipsaci on cultivated plants has never been completely explained. Goodey (1933 and 1936) has summarised the information on the subject of seed-borne infection by means of the seeds of cultivated and wild hosts. The same writer also suggests that weeds may play an important rôle in maintaining an active eelworm infestation in the soil by acting as hosts for strains of the eelworm capable of producing diseased conditions in cultivated crops.

This study was conducted to determine infection with nematode parasite Philometra sp. in gonads of Serranus cabrilla recorded in Izmir Gulf between October 2016 and July 2017. The overall prevalence was 14.46% and the mean intensity of infection 1.2 parasites per fish. The occurrence of philometrid infection on comber hosts was assessed according to several risk factors (fish length class, sex and season). Our findings suggest that the highest rates of parasite infection occur in larger sized fish, hermaphrodite individuals and during April month. The present report also revealed that marked hyperemia was the major findings of infected gonads of S. cabrilla, where parasitic nematodes caused a marked inflammatory reaction at the histopathological examination. As far as we know, this paper represents the first mention of genus Philometra in S. cabrilla from Turkey and the first presence of philometrid parasites in Aegean coast of Turkey. Furthermore, the present work is the first record of the effects of Philometra sp. parasitism on a serranid species in Izmir Gulf.

Abstract One new and one known species of parasitic nematodes are reported from Thailand for the first time: Falcaustra kaverii (Karve et Naik,1951) (Kathlaniidae) from the intestine of the freshwater fish Poropuntius deauratus (Valenciennes) (Cyprinidae) (new host record) and Ascarophis scatophagi sp. nov. (Cystidicolidae) from the intestine of the marine fish Scatophagus argus (Linnaeus) (Scatophagidae). The morphology of both these species was studied with the use of light (LM) and scanning electron microscopy (SEM) (the latter method used for F. kaverii for the first time). The new species (A. scatophagi) is mainly characterized by nonfilamented, markedly elongate-oval eggs (size 42–45 × 18 μm), spicules 555–642 μm and 105–150 μm long, the muscular/glandular oesophagus length ratio (1:13–34), bifurcate deirids, the length of the female tail (159–249 μm) and cephalic structures typical of the nominotypical subgenus Ascarophis. Representatives of Falcaustra Lane, 1915 and Ascarophis van Beneden, 1871 were not previously reported from fishes in Thai waters.

1. A new species of Oxysomatium (O. minutum) is described from a frog Rana ptychadena mascareniensis.2. The crested chameleon (C.? cristatus) and Bufo supercilioris are reported as new species of hosts recorded for Africana africana (Gendre, 1909) Travassos, 1920.3. Strongyluris brevicandata Müller, 1894 and Thelandros sp. are reported from Agama agama agama.4. Amplicaecum involutum (Gedoelst, 1916) Yorke and Maplestone, 1926 is redescribed from Chamaeleon (?) cristatus which is regarded as a new host record and A. pesteri n.sp. from Bufo superciloris is described to be the smallest species of this genus.

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.

AbstractTwo species of parasitic nematodes, Heliconema ahiri Karve, 1941 (Physalopteridae) and Procamallanus (Spirocamallanus) anguillae Moravec et al., 2006 (Camallanidae), were recorded from the Indonesian shortfin eel Anguilla bicolor bicolor Mc-Clelland in the Chalakkudi River and Veli Lake, respectively, both Kerala, India. The former species (H. ahiri), rediscovered from eels in India after 82 years from its original description, has been redescribed and revalidated based on its specific feature (presence of groups of minute denticles in the mouth) distinguishing it from other congeners; its finding in A. b. bicolor represents a new host record. The latter species (P. anguillae) has been recorded in India for the first time. SEM examination of its first-stage larvae from uterus has shown that P. anguillae is another species of Procamallanus whose larvae possess a crown of digit-like processes at the tail tip.

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.
