Abstract

American elm trees, Ulmus americana L., were sprayed with methoxychlor by helicopter or mist blower, and twig crotches were collected from sprayed trees for bioassay of Scolytus multistriatus (Marsham) and GLC assay. Correlations established between the 2 assays were dependent on method of application and amount of methoxychlor residue. Correlations were low and variable for helicopter-sprayed trees and high and uniform for mist-blower-sprayed trees.
