Two insecticides, carbaryl and chlorpyrifos, were evaluated at low concentrations as tracers to predict the behaviour of spray clouds of malathion at field strength. Aerial sprays were produced from a Cessna Ag Husky equipped with a dual liquid dispe

Host preference of mosquitoes was determined using animal-baited traps. Hosts used in the study were cattle, chickens, dogs, and horses. Ten mosquito species representing 4 genera were collected from the animal-baited traps. Aedes vexans, Aedes dorsa

Attraction, engorgement, mortality, and fecundity were observed on host-seeking Aedes vexans and Psorophora confinnis given the opportunity to feed on insecticide-treated steers in stable traps. Individual steers were treated with Ectrin ear tags, Ec

A method is described for the determination of lead in blood covering the range 5 to 100 µg of lead per 100 g of blood (0.05 to 1 ppm). Lead is extracted from uncoagulated whole blood using a trichloroacetic acid (TCA) solution. A portion of the sup
