The incidence and degree of infection by P. tenuis was studied in western Virginia deer herds (Odocoileus virginianus). The objectives of the research were (1) to determine the distribution of pneumostrongylids in the white-tailed deer in seven western Virginia counties and (2) to correlate incidence and degree of infection by pneumostrongylids with deer age, sex, geographic location, and physical condition. Specimens were collected from Shenandoah, Augusta, Bath, Rockbridge, Botetourt, Giles, and Craig counties. Deer heads were obtained from hunters at check stations. Three-hundred and nine deer heads, 230 does and 79 bucks, were examined for P. tenuis and 73% were infected. The majority of the worms (68%) were found on the dorsal surface of the brain. The range of infection was 1-13 worms. In addition, lung and fecal specimens were collected. Fifty per cent of the lung specimens were infected, but no larvae were round in the fecal material.

Due to a combination of factors, Lake Catherine, a 3,000 - acre reservoir which had never known a vegetation problem, suddenly became congested with rooted aquatic vegetation in 1960. The vegetation, mostly coontail, Ceratophyllum demersum,and Elodea sp., could be controlled with chemicals and consequently various chemicals were used by the riparian property owners on small localized areas. However, for the larger, main body of the lake, chemical herbicides were considered too expensive to be practical. In October 1960 the Arkansas Game and Fish Commission was petitioned both by the sportsmen in the area, the riparian property owners, and the Arkansas Power and Light Company (owners of the dam and reservoir), to advance a plan for the control of the vegetation. The formulation and the carrying out of that plan is discussed, with emphasis on the combination of two biological methods of control

The growth rate data indicated that diets containing casein and the protein combination produced approximately equal growth and that both of these protein sources produced better growth than soybean protein alone. Fish receiving diets containing 30 per cent protein gained at a significantly higher rate than fish receiving diets containing five per cent protein. The relative order of growth rates for the three sources of protein was the same at both levels of protein in the diet.
