Fly sprays of petroleum oils carrying pyrethrum, pine oil, or both, designed to keep flies from dairy cows were tested for their efficiency. It was shown that all had approximately the same efficiency for the first hour but differed at subsequent intervals, pine oil increasing their efficiency ...

A 0.5% malathion emulsion spray was contaminated with 1, 5 or 10 p.p.m. dieldrin and applied to cattle at 1 US gal/head in Texas for control of Haematobia irritans (L.). Each level of dieldrin was applied to two steers at intervals of 3 weeks. Samples of tissue were analysed for ...
for 4 fly seasons during 17-wk periods within the months of May through September of each year. The trap was positioned in an alleyway at the exit of an open-sided milking parlor at the research dairy (Figure 2). Cows passed through the unit in single file, twice daily, as ...
Consequently, there is a relationship between fly abundance and transmission of bacteria resulting in intramammary infections and mastitis in dairy cows. The use of the pyrethroid deltamethrin reduced fly abundance and therefore, the possibility of transmitting pathogenic bacteria in the mammary gland....
A group of ten dairy cows were treated for warble-fly with the organophosphorus pesticide, crufomate. The persistence of crufomate in the milk of the cows after treatment was determined by gas-liquid chromatography with a phosphorus-specific thermionic detector. The mean crufomate concentration ...
Persistence of the organophosphorus pesticide, phosmet, in the milk of 10 dairy cows was determined following treatment of the animals for warble-fly. The mean phosmet concentration in the milk was at a peak level (0.04 mg kg−1) 12 h after treatment. The extent of phosmet elimination ...
