Abstract

It is known that selenium is highly toxic to mammals (1, 3) and to some insects (6, 8). Aphids cannot tolerate any appreciable quantities of selenium in host plants (4, 5, 10). A selenium content higher than 5 p.p.m. in cotton plants was reported toxic to cotton stainers (Dysdercus howardi Ballou) and to pink bollworm (Platyedia gossypiella Saund.) (6, 8).
