Abstract

In a survey during 1935 the leaves on 25 plants in each of 385 fields well distributed over S. Carolina, N. Carolina, and Virginia were examined for feeding injury by various insects. 94.04% had been injured by flea beetles (Epitrix spp.), 36.93% by hornworms (Protoparce spp.), 9.68% by budworms (Heliothis spp.), and 2.76% by grasshoppers. Only 2.15% of all leaves were uninjured. E. parvula, P. sexta, and Heliothis spp. were responsible for the major portion of leaf injury observed, although occasional injury was noted from feeding by the suckfly, Dicyphus minimus. tree crickets, Oecanthus spp., and by the tobacco split-worm. Phthorimea operculella.
