The stem and bulb nematode (Ditylenchus dipsaci) is a serious quarantine pest of vegetables spreading worldwide via seed and planting material. Currently, a hot water technique is used as the pre-seed treatment, which is difficult to execute and the risk of seed damage is high. The objectives of this study were to evaluate the (a) penetration of gaseous hydrogen cyanide (HCN) into garlic tissue...

during a survey of plant-parasitic nematodes in bamyan and mazar sharif provinces of afghanistan, several species of plant-parasitic nematodes belonging to infraorder tylenchomorpha were detected and identified. filenchus facultativus; filenchus discrepans; filenchus elegantulus; boleodorus volutus; neopsilenchus magnidens; coslenchus costatus; ditylenchus myceliophagus; tylenchorhynchus clarus...

Anguina plantaginis n. sp., parasitic on Plantago aristata, is described and illustrated. This new species is most closely related to A. klebahni, A. millefolii, A. mobilis, and A. moxae and is characterized as follows: moderate body size for the genus; absence of esophageal "storage organ"; postvulval uterine sac extending about 45% of vulva-anus distance; crustaformeria of young females longe...

We conducted a species-level study of molluscs associated with a 5 m long 17 carcass of a minke whale at a depth of 125 m in the Kosterfjord (North Sea, Sweden). The 18 whale fall community was quantitatively compared with the community commonly living in 19 the surrounding soft-bottom sediments. Five years after the deployment of the dead whale at 20 the sea floor, the sediments around the wha...

Sweet potato is infested by root-knot and reinform nematodes. Root-knot nematode infestation in sweet potato is studied in detail. A number of resistant varieties are released in sweet potato from USA, Japan and China. A number of germplasm accessions and cultivars/ varieties were found resistant to the nematodes in Peru. Studies carried out by the authors indicated that sweet potato germplasm ...
