Abstract
During the summer of 1949 studies were conducted at Princeton, N. J. to determine effects on wildlife of DDT used in control of Dutch elm disease. Intensive search for dead animals yielded 26 songbirds, one red bat (Lasiurus borealis). one gray squirrel (Sciurus carolinensis). Only one of 11 dead birds from a 20-acre study area was an adult. Songbird populations were detd. by censuses before and after spraying. When spp. common to both sprayed and unsprayed areas were considered, a population decline of 22% was measured in the sprayed area, while a 6% increase occurred on a similar unsprayed check area, over the same period. Nestling mortality was studied in both areas. Among 18 young found on the study area during and following spraying, 8 (44%) survived. Of 21 young found on the unsprayed check area 15 (71%) survived.This publication has 1 reference indexed in Scilit:
