Root knot nematode, Meloidogyne spp. causes severe yield losses in vegetable crops. Chitosan is one of the most abundant biopolymer available worldwide next to cellulose. It known have anti-nemic, anti-fungal and anti- bacterial properties. Application chitosan induces systemic resistance tomato plants against pathogens by increasing phenolic content antioxidant enzymes viz., Polyphenol oxidase...

A study was conducted to evaluate the relative resistance to a natural or induced gastrointestinal (GI) nematode infection in hair and wool breeds of lambs. In Experiment 1, natural GI nematode infection was evaluated among fall born Dorper crossbred (DO; n = 17) or St. Croix (SC; n = 17) lambs. Ewe and wether lambs were weaned at 84 ± 1.1 days of age and dewormed. Fecal egg counts (FECs) and b...

Rotylenchulus reniformis is the predominant parasitic nematode of cotton in the Mid South area of the United States. Although variable levels of infection and morphological differences have been reported for this nematode, genetic variability has been more elusive. We developed microsatellite-enriched libraries for R. reniformis, produced 1152 clones, assembled 694 contigs, detected 783 simple ...

Title of thesis: PHYSIOLOGICAL AND MOLECULAR STUDIES OF ETHYLENE EFFECTS ON SOYBEAN ROOT INFECTION BY SOYBEAN CYST NEMATODES Ping Xue, Master of Science, 2007 Directed By: Dr. Theophanes Solomos, Department of Plant Science and Landscape Architecture Soybean cyst nematode (SCN), Heterodera glycines, is one of the most devastating pests of soybean in the world. Several earlier reports demonstrat...

one of the methods for controlling cucumber root-knot nematode is the use of plant extracts that have nematicidal effect. in this research, sweet wormwood and castor bean were selected and their anti-nematode activity has been investigated against cucumber root-knot nematode (meloidogyne incognita) in laboratory and greenhouse. experiments were carried out by using randomized completely design ...

The development of the filarial nematode Brugia pahangi was monitored and compared in susceptible (BLACK EYE) and refractory (ROCK) strains of Aedes aegypti. Simultaneously, the activities of acid phosphatase, beta-glucuronidase, alpha-glucosidase, and N-acetyl-beta-glucosaminidase were measured. Three- to five-day-old females of both strains were fed on infected and uninfected clawed jirds (Me...
