Plant-parasitic nematodes can affect seedling production in forest nurseries when host seedlings are developmentally vulnerable, nematode populations are high, or opportunistic pathogens are present. Soil fumigation has been important for plant-parasitic nematode control in forest nurseries. Regulatory changes and rising costs of fumigant application are expected to affect nursery pest manageme...

Purpose To characterize a new species of parasitic nematode that triggers uveitis. Observations Three previously healthy, relatively young people each contracted a corneal stromal nematode that, upon surgical removal and examination, did not match any known nematodes. Clinical ocular findings included corneal opacification, visible corneal worms, conjunctival injection, and uveitis. Conclus...

the relationship between initial population density of rice white tip nematode (aphelenchoides besseyi) and yield was examined on oryzae sativa cv. alikazemi. experiments were conducted in greenhouse, micro-plot and field conditions. seinhorst’s model was used to describe the relationship between nematode population density and crop yield. the parameters of the model, minimum yield (m), constan...

The recent de-registration of several chemical nematicides and the impending loss of methyl bromide from the pest-control market necessitate the development of new methods for controlling nematode-induced crop damage. One approach for developing novel target-specific controls is by exploiting fundamental differences between the biological processes of nematodes and their host plants. Researcher...

Growth, yield, and quality of 10 sweet potato selections and reproduction of the reniform nematode, Rotylenchulus reniformis, were studied in fumigated and nonfumigated plots in a naturally infested field. Nematode reproduction on the different selections in the field was similar to that reported in the greenhouse but was not related to the effect of the nematode on yield of the different selec...

Methods We examined 400 consecutive patients presenting to the endocrinology/dermatology department of a tertiary care referral hospital in Bangalore who were diagnosed with AITD between the periods from 06/07 – 06/10 on an outpatient basis. Detailed history and physical examination including cutaneous examination was done. Mean follow up was done for the period of 6 months for the cutaneous ma...

Chitin was used as soil amendment in fiberglass field microplots, alone or with one or a combination of two to three species of Hirsutella rhossiliensis, Paecilomyces marquandii, Verticillium chlamydosporium, Bacillus thuringiensis, and Streptomyces costaricanus. Sudangrass and rapeseed were planted as cover crops and incorporated into soil as green manure amendments. Chitin amendment alone inc...

To assess the role of macrofauna-mediated sediment changes on nematode community recovery, we examined the temporal development of macrobenthos, nematode communities and sediment properties following hypoxia in 16 m2 replicated plots over a 6 mo period. Hypoxia drastically changed nematode community composition (i.e. reduced diversity and abundances of all dominant nematodes, except Odontophora...

In April 2008, 120 soil samples from 24 locations were collected in Gorenjska, Notranjska and Primorska regions as well as in Ljubljansko barje. The presence of entomopathogenic nematodes was confirmed in 9 samples from 6 locations. Only the sample C101, which was taken in the village Svino in the area of Breginjski kot (western part of Slovenia, the vicinity of Italian border), was sent to gen...
