Field Application of Acaricides to Floor Birds 



Birds were suspended by their feet and sprayed individually. The 

 area between the keel bone and the tail was thoroughly saturated with 

 the acaricide solution. Application was made with a B.& G. can. Litter 

 was not treated. 

 Compounds Utilized for Fly or Mite Control 



Common names, code letters and numbers and/or trademarks of the 

 compounds utilized in this study are shown in Table 2. Names which are 

 in accordance with the principles of Chemical Abstracts nomenclature 

 are given if available (Kenaga and End, 197*0. If the compound was 

 supplied by a cooperator, the manufacturer's name is included. Compounds 

 without a manufacturer's name were purchased locally. 

 Treatment of Data 



Statistical Analysis System (SAS) . Data were analyzed at the 

 Northeast Regional Data Center (NERDL) , University of Florida, Gaines- 

 ville, Florida, using the Statistical Analysis System (SAS) of Barr 

 et al. (1976, 1979). 



Comparison of means. Methods for comparison of means, such as chi 

 square and Tukey, were found in Snedecor (1961) and Freese ( 1 5 6 3 ) - 

 Duncan's multiple range tests were performed by SAS. 



Probit analysis. Probit analysis and the plotting of dosage- 

 mortality curves were performed by SAS. An in-depth explanation of 

 probit analysis and the calculation of a probit line was found in 

 Finney (1964). Aid in interpretation of probit lines was given by 

 Hoskins and Gordon (1956) and Tsukamoto (1963). 



Correction of mortality. Where applicable, the results of pesti- 

 cide trials were corrected by the methods of Abbott (1925).
