Acute toxicity studies with insect attractants

Morton Beroza; May N. Inscoe; P. H. Schwartz; M.L. Keplinger; C.W. Mastri

Abstract Eight insect attractants and one inhibitor of a sex attractant were tested for acute oral and aerosol inhalation toxicity in rats, for acute dermal toxicity, eye irritation, and primary skin irritation on rabbits, and for toxicity to rainbow trout and bluegill sunfish. Except for phenethyl propionate + eugenol, 7:3 (acute dermal LD50, 1220 mg/kg), none of the test materials was classified as more than slightly toxic. (Z)-7-Dodecen-1-ol acted as a primary skin irritant, since it caused superficial chemical burns.
