A spectrophotometric technique for measuring particle ingestion by black fly larvae

Autor: Elmer W. Gray, Joseph P. Iburg, Roger D. Wyatt, Raymond Noblet

Publikováno v: Entomologia Experimentalis et Applicata. 146:293-301

A spectrophotometric technique was developed to provide insight into the feeding behavior of Simulium vittatum Zetterstedt (Diptera: Simuliidae) larvae. Larvae were exposed to water insoluble Neon Red particles (NRP) (DayGlo®) in a controlled curren

Field Evaluation of Bactimos Pt Against Chironomid Midge (Diptera: Chironomidae) Larvae in Residential Ponds

Autor: Robert A. Fusco, Ray Noblet, Elmer W. Gray, Roger D. Wyatt, Candace Royals

Publikováno v: Journal of the American Mosquito Control Association. 27:173-176

We evaluated Bactimos PT (Bacillus thuringiensis subsp. israelensis [Bti]) against larval populations of Glyptotendipes paripes at 30 kg/ha in man-made lakes on Hilton Head Island, SC. Three treatments were “whole-pond” treatments, while the 4th

Investigation of Resistance of Bacteria from Commercial Poultry Sources to Commercial Disinfectants

Autor: Jean E. Sander, I-Hsin Cheng, Roger D. Wyatt, Charles L. Hofacre

Publikováno v: Avian Diseases. 46:997-1000

Concern by consumers about food safety has resulted in increased pressure on poultry companies to develop effective sanitation programs. Salmonella isolates in hatcheries are often the same species isolated from processing plants. Resistance develops

The Toxicity of Fumonisin B1, B2, and B3, Individually and in Combination, in Chicken Embryos

Autor: Roger D. Wyatt, M. H. Henry

Publikováno v: Poultry Science. 80:401-407

Three recently described and toxicologically important mycotoxins, fumonisin B1 (FB1), fumonisin B2 (FB2), and fumonisin B3 (FB3), produced by Fusarium moniliforme in various grains, have been associated with a number of diseases in both humans and a
