limited studies have been done on nematodes of bellamya bengalensis (fresh water snails) in the world. following, our clinical observations on eye disease in a fish ponds, which were contained bellamaya bengallensis snails, present study was made to determine of nematodes fauna of bellamya bengalensis and evaluation of their medical and veterinary importance in khouzestan province. for this pur...

root-knot nematodes, meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. the most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. in the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. in the supplementary studie...

Carbon-based engineered nanomaterials, such as graphene oxide nanoparticles (GO NPs), are widely available for application, but their potentially adverse health effects on humans still require investigation. In this study, the environmental levels of GO NPs addressed to examine whether leads an in-vivo model Caenorhabditis elegans (C. elegans). Nematodes with prolonged exposure (L1 larvae young...

Nematodes are common pests that damage agricultural crop plants. Some of them beneficial while others parasitic and harmful to plants, animals humans. Several in vitro studies have aimed develop chemicals kill nematodes, been conducted use nematodes as biocontrol agents. However, the preparation large quantities nematode eggs a laboratory setting is challenging. Traditional egg isolation protoc...

The susceptibility of adult sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), to five local Syrian isolates of Heterorhabditis bacteriophora, Steinernema riobravae Texas, S. carpocapsae C3B, and H. bacteriophora 8-14 strains was evaluated under laboratory conditions. Concentrations of 50, 100, 200, and 400 nematodes per adult were bioassayed; for each nematode concentration, f...

Previous research has shown that population densities of plant-parasitic nematodes are reduced when a legume crop is grown in rotation with sugarcane. However, this effect is only temporary, as nematodes usually return to high densities within 12 months of planting sugarcane. This rapid resurgence suggests that natural enemies that normally keep plant-parasitic nematodes under control in natura...
