During the 1941 growing season, field observations in western Nebraska indicated that aphids, Myzus persicae (Sulz.), were becoming abundant in experimental potato plots that had been treated with zinc arsenite-lime sulfur spray for controlling potato flea beetles, Epitrix cucumeris (Harr.), and the potato psyllid, Paratrioza cockerelli (Sulc.). Detailed examinations of leaves showed that significantly greater populations were present on the sprayed than on the untreated plants. Evidence of slight increases also was noted on plants dusted with a barium fluosilicate and sulfur mixture.
