A life history study of the yellow throat
Investigations concerning the life history of the Yellow-throat were made in southern Michigan during the spring and summer of 1938. Supplementary information was also obtained at Arlington, Virginia, in 1940 and at the Patuxent Research Refuge, Maryland, in 1947.....Resident males established territories almost immediately upon arrival in spring. In southern Michigan some resident males arrived a

Control of Japanese honeysuckle in wildlife borders
1. Japanese honeysuckle, an exotic that can be either a pest or an asset in different localities, makes maintenance of wildlife plantings in the Southeast a difficult problem. 2. A herbicide applied during the winter and strong enough to kill dormant woody plants will stop the spread of honeysuckle from a woods edge for at least two years. 3. A low-percentage 2,4-D water spray applied to hon

Occurrence of amidostomum in Canada geese
The gizzard nematode, Amidostomum anseris, has been reported frequently as the cause of losses among domestic geese in Europe. Cram's (1925) report of an outbreak in domestic geese in New York State was the first evidence of this worm in North America and since then there have been several reports of its occurrence in many parts of Canada and the United States. There have been a few cases of A.

Relationship between chemical structure and rat repellency
Repellent activity is defined as the activity of a compound in preventing consumption of, or gnawing attacks upon, foodstuffs or articles containing or treated with the candidate substance. Data are presented on repellency indices of 2700 compounds, and it is shown that repellency is associated with specific functional groups attached to alkyl, aryl, or heterocyclic nuclei. Functional groups conta

Rodent repellent studies. IV. Preparation and properties of trinitrobenzene-aryl amine complexes
Data are presented on methods of preparation, chemical arid physical characteristics, toxicity, and repellency to rodents of complexes of symmetrical trinitrohenzene with various aromatic amines: When applied in suitable carriers or incorporated in plastic .films, members of this series ofmaterials were shown to offer significant increases in time required by wild rodents to damage common packagin
