The Utility of DDT for the Control of Poultry Ectoparasites

Comparative Efficacy of Several Insecticides and Methods of Application in the Control of Lice on Chickens

“…However, a review of all experiments reveals that, with one or two exceptions, the control achieved even with the highest concentrations did not equal that obtained with full strength sodium fluoride dust. Twenty percent DDT dusted over birds with a garden duster in much the same manner as recommended by Quigley and Cory (1946) failed to result in louse control comparable to that attained following other methods of applying DDT or applications of several other compounds. Even if lice had been controlled successfully by this method, it is questionable that birds should breathe a fog of DDT for 30 minutes or more.…”

“…Telford (1944) reported that 33% sodium fluoride in pyrophyllite was effective against shaft and body lice. Telford (1944 and, Warren (1945), Quigley and Cory (1946), Alicata et al (1946 and and others have reported on the use of DDT and other compounds in chicken louse control. Telford (1944) found 0.5 to 4% DDT in pyrophyllite to be effective against shaft and body lice when birds were dusted individually.…”

“…Alicata et al (1946) found 5% DDT dust effective against body and wing lice, but not wing mites. Quigley and Cory (1946) reported excellent louse control by treating birds while roosting with 20% DDT dust by means of a garden duster. In 1947, Alicata et al reported that a combination of DDT and Lethane sprayed over birds offered a better measure of control of body lice and body mites than when either material was used alone.…”
