A filamentous, nonsporulating fungus, designated Arkansas Fungus 18 (ARF18), was isolated from 9 of 95 populations of Heterodera glycines, the soybean cyst nematode, in Arkansas. In petri dishes, ARF18 parasitized 89% of H. glycines eggs in cysts. The fungus also infected eggs of Meloidogyne incognita and eggs in cysts of Cactodera betulae, H. graminophila, H. lespedezae, H. leuceilyma, H. scha...

Eggs of Meloidogyne arenaria race 1 were encapsulated in calcium alginate for use as inoculum to infest peanut field plots. Some eggs within the capsules remained viable up to 10 weeks after preparation. A field site was successfully infested at peanut planting and (or) 6 weeks later. Dual applications of nematode inoculum (at planting and 6 weeks later) were superior to single applications (at...

Medium-chain fatty acids (MCFAs) consisting of 8 to 12 carbons are knowns exhibit antimicrobial activity against bacteria and gut protozoa. However, little information is available on their effect in helminthes. The effect of MCFA on an intestinal nematode (Nematodirus sp.) was therefore evaluated in four calves (4 to 11 month old). Edible fat containing MCFA was administered into the abomasum ...

Factors that influence the success of a cattle breeding business are seeds, feed and health management in form disease control. The often occurs is helminthiasis. This research was to analyze an incidence helminthiasis beef cattle. used observation method. Data collection done by taking all fecal samples from 391 Seputih Raman sub-district. A examination checked with Mc. Master Sedimentation te...

Development of the sugar beet cyst nematode, Heterodera schachtii, was studied in growth chambers at 20, 25, 29, 32 and 35 ± 1 oC on Beta vulgaris cv. Saccharifera. The optimum temperature for reproduction appeared to be 32 oC, at which the life cycle, from second-stage juvenile (J2) to J2, was completed in 16-19 days; at 35 oC, 20-21 days were required. Juveniles emerged from eggs within 29 da...

A new species of trichosomoidid nematode, Huffmanela paronai sp. n., is established on the basis of its egg morphology and biological characters. The dark-shelled, embryonated eggs of this histozoic parasite occur in masses in the epidermis of the swordfish Xiphias gladius L. (Xiphiidae, Perciformes) from the Ligurian Sea in northern Italy. The eggs are concentrated in groups appearing as black...

The importance of oxygen availability in the embryonation of the infective egg stages of the gastrointestinal nematode parasite Heterakis gallinarum was studied in the laboratory. Unembryonated H. gallinarum eggs were kept under either aerobic conditions by gassing with oxygen, or anaerobic conditions by gassing with the inert gas nitrogen, under a range of constant temperatures. Oxygenated egg...

We provided fenbendazole to captive (N q 77) and free-ranging (3 study areas) white-tailed deer (Odocoileus virginianus) in Louisiana to determine effects on gastrointestinal nematode burdens. Fenbendazole reduced gastrointestinal nematode burdens of captive and free-ranging white-tailed deer. Mean eggs per gram of feces from captive deer decreased P<O.Ol and P<O.Ol, respectively) 89% and 84% a...
