Some toxicological aspects of Ruelene, an organophosphate, used systemically to control ectoparasites

Creator:: Smith, Harry Glen
Abstract:: Ruelene was orally administered to three female sheep at a dosage rate of 121.5 mg /kg. The cholinesterase (ChE) activity levels of blood plasma, red blood cells (RBC), and mosquitoes (Aedes aegypti) which had fed on the sheep were tested at various times before and after dosage. Maximum depression of...

Biological and ecological aspects of the black flies of the Marys River drainage system (Diptera: Simuliidae)

Creator:: Speir, Jon Allen
Abstract:: Members of the family Simuliidae were studied in a single, confined drainage system. In addition to determining the occurrence and distribution of the species present, biological and ecological observations were made. Specific measurements and observations were accomplished to determine as much as possible about the habitat specificity and life cycle...
