Trials were conducted to evaluate the efficacy of permethrin and fenvalerate, two synthetic pyrethroid compounds, for the control of the northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), on White Leghorn hens. Fenvalerate at .0125%, .025%, and .05% active ingredient (ai) were as effective as carbaryl at .5% ai for 56 days posttreatment. Permethrin at .01%, .025%, and .05% ai were as effective, or better than, malathion at .27% ai for 56 days posttreatment. All treatments were applied to the birds as high pressure sprays.
A total of 160 turkeys equally divided among weights ranging from 3.5-11.0 kg were cooked with or without stuffing in covered Pans or under aluminum foil caps. End-point temperatures were determined in the breast, thigh, body cavity, and just under the skin. Cooking in a 163°C oven was continued until thigh temperature was 82°C. Meat, bone, and skin weights were determined on cooked birds. Either thigh or the breast can be used to determine end-point temperatures. In terms of servings of white meat, no particular advantage was found for any of the sizes studied. Recommended cooking times (min/kilo) for turkeys are: Size (kg) 3.6-5.4
The insect growth regulator, CGA 72662 (N-cyclopropyl-1,3,5-triazine-2,4,6-triamine), was tested both as a topical spray and feed additive for controlling the house fly (Musca domestica L.) breeding in chicken manure. Dosage concentrations of .025%, .05%, and .1% were sprayed on sections of manure surface in a shallow pit egg layer operation at rates of 1.9 and 3.8 liters/10.2m2. AT 17 days posttreatment each concentration at both rats, except .025% at 1.9 liters/10.2m2, provided at least a 70% reduction of native house flies and 100% inhibition of laboratory reared house flies. CGA 72662 fed to both hens and broilers at rates of 1.5 ppm and 5 ppm provided up to 100% mortality of house flies 1 day after birds were started on treated feed to 1 day after treated feed was removed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
