Abstract
In trapping aphids with tanglefoot screens, sticky boards, wind traps and yellow trap pans, the last were the most effective. Sixty-six percent were caught at ground level and decreasing numbers as the elevation was increased to 20 ft. A list of the species taken in the traps and collected directly from plants is given.This publication has 1 reference indexed in Scilit:
