Abstract

Although no adverse effects were documented, this study did not provide data sufficient to adequately test for effects of aerial spraying of esfenvalerate on small mammal populations or nesting of birds in Douglas-fir seed orchards. Small mammal trapping data were too sparse to provide statistical testing with reasonable power. Residues of the R and S forms of fenvalerate were low with maxima of 0.56 and 1.72 ?g/g, respectively in pelage of a deer mouse. No diagnostic residue data are available to interpret our results.
