In Hanover, New Hampshire, where elms were sprayed with DDT, 151 dead birds were found; 10 dead birds were found in Norwich, Vermont, where no DDT was used. Chemical analyses of dead birds, observation of symptoms of DDT poisoning, and a population decline after spraying all indicate severe mortality among certain species in Hanover. 
Bird Mortality Following DDT Spray for Dutch Elm Disease
Feeding habits suggest that some birds acquired the toxicant by eating living insects carrying DDT, presenting the paradox of survival of the intended DDT victims, and death, instead, of insectivorous birds.
Some effects of Dutch elm disease on nesting farmland birds
Certain arboreal bird species have benefitted in the short term from Dutch elm disease, though others appear to have suffered. This review of nest record and census data attempts to assess the impact
Persistence of DDT in Wild Populations of Small Mammals
Data is presented of pesticide residues from small mammals covering a period of 9 years after single applications of DDT applied to forests at a rate of 0.89 kg/hectare (1 pound/acre).
Effects of DDT treatments applied for tsetse fly control on white‐browed sparrow‐weaver (Plocepasser mahali) populations in NW Zimbabwe
Summary Colony density and size, and numbers of white-browed sparrow-weavers were investigated in Colophospermum mopane-Julbernardia globiflora woodland treated from nought to five times with DDT
DDT Residues in an East Coast Estuary: A Case of Biological Concentration of a Persistent Insecticide
High concentrations of DDT in soil of an extensive salt marsh on the south shore of Long Island suggest that many natural populations in this area are now being affected, possibly limited, by DDT residues.
Pesticides and Bird Populations
This chapter reviews the principal impacts upon bird populations of the uses of biocidal chemicals. Of necessity, the coverage is restricted to those areas of the world for which sufficient
Occurrence and consequences of DDT residues in woodland birds following tsetse fly spraying operations in NW Zimbabwe
Populations of the wood-hoopoe and chat declined over 2-3 years in sprayed areas by about 90%, but no differences attributable to spraying were detected in the other species, and DDT residue concentrations 1-3 months after treatment reflected feeding site more than diet.
DDT residues in robins and earthworms associated with contaminated forest soils.
Residue analysis of forest soils sprayed once at 1 lb/acre showed little breakdown of DDT through 9 years after application. In the absence of appreciable downward trend, residue persistence could
The race to prevent the extinction of South Asian vultures
It may be some years before diclofenac is removed from the vultures' food supply, and captive populations of three vulture species have been established to provide sources of birds for future reintroduction programmes.
Effects of DDT treatments applied for tsetse fly control on White-headed Black Chat (Thamnolaea arnoti) populations in Zimbabwe. Part II: cause of decline
It is concluded that DDT spraying did not reduce availability of prey or fledging success, and initial population decline in sprayed areas was due to a lethal accumulation of DDT residues from prey, especially Camponotus spp.


Initial songbird mortality following a Dutch Elm disease control program.
Three methods have been subsequently used which have been thought to reduce this mortality of songbirds following field applications of DDT during the insect-control programs.
Persistence of DDT in Soils of Heavily Sprayed Forest Stands
Soils from DDT-sprayed forest stands in New Brunswick and Maine contained DDT residues. The residues increased in successive samplings between 1958 and 1961, although no new spray was applied. The
Wildlife effects of DDT dust used for tick control on a Texas prairie
A large scale field triai of the value of DDT in control of the Lone Star tick (Amblyomma americanum) was made by the U. S. Army and the U. S. Department of Agriculture in the summer of 1947. A 10
Effects on wildlife of DDT used for control of Dutch elm disease
Results would appear to be applicable to the Dutch elm disease problem as it exists elsewhere in the nation and this report summarizes results of the first summer's work on the problem.
Insecticides to Prevent the Emergence of Scolytus multistriatus
Emulsions of four insecticides were tested for their effectiveness in preventing emergence of the smaller European elm bark beetle, Scolytus multistriatus (Marsh.), and Lindane was most effective, followed by dieldrin and DDT in reducing emergence.
Effects of DDT on bird population of scrub forest
The present study details the effects on a bird population of a five-pound-per-acre application of DDT where the nature of the cover was such that little "screening out" of the spray occurred, and approximated conditions that might be met in comparable control attempts in some agricultural situations.
Effects on forest birds of DDT used for gypsy moth control in Pennsylvania
Between April 18 and June 28, 1945, the birds populations on three tracts near Scranton, Lackawanna County, Pennsylvania were determined by repeated, systematic census trips. One tract ("Mile
Poisoning by DDT: Relation between Clinical Signs and Concentration in Rat Brain
The severity of signs of poisoning in rats after a single dose of DDT is directly proportional to the concentration of the compound in their brains. The concentrations associated with death after one
Disappearance and visibility of quail remains
To determine the rate of disappearance of loose feathers, 40 assortments were placed in rows at Union Springs in 1957 and tests were conducted on two areas, one at Gadsden, Alabama, and another at Buna.
