The isolation and identification of Trypanosoma cruzi from raccoons in Maryland
Five raccoons trapped at Patuxent Research Refuge, Laurel, Maryland, were found to have trypanosomes in the blood which were morphologically indistinguishable from Trypanosoma cruzi on stained smears. The organism grew well in culture. It developed and reproduced in Triatoma protracta, T. infestans, T. phyllosoma, and Rhodnius prolixus. Experimental infections were produced in raccoons, opossums,

Mass control of insects: The effects on fish and wildlife
The mass control of insects carried on during the past ten years has made possible the economical suppression and, in a few instances, the near eradication of pest insect populations over widespread areas. These large operations, usually featuring the use of the airplane for applying insecticides quickly and cheaply, have proven to be the means of effectuating control programs which never could ha

Racial determination of origin of mourning doves in hunters' bags
A method is described for determining the general area of production of mourning doves that are shot during the hunting season. This procedure is based on the identification of racial characteristics that can be ascertained from samples of wings. The application and utility of this method were demonstrated with data gathered from doves shot in two important dove-hunting areas, Georgia and Texas. T

A procedure for removing the effect of response bias errors from waterfowl hunter questionnaire responses
Response bias errors are studied by comparing questionnaire responses from waterfowl hunters using four large public hunting areas with actual hunting data from these areas during two hunting seasons. To the extent that the data permit, the sources of the error in the responses were studied and the contribution of each type to the total error was measured. Response bias errors, including both pr

Chemicals and wildlife
Short paper that reviews some of the facts about effects of insecticides on wildlife and states principles that should be followed for maximum safety in treatment. These principles include minimal doses, good ground-to-plane control to avoid overdoses, and least possible pollution of water areas.
