Abstract

Olfactory responses of 72- to 96-h-old, 24-h-starved adult males, females, or mixed-sex groups of Tribolium castaneum (Hbst.) to volatiles from wheat and millet kernels, certain milled fractions and solvent extracts were recorded by using a light-sensitive apparatus. Wheat-germ volatiles from intact germ or solvent extracts were generally more attractive than volatiles of wheat endosperm or wheat bran. Volatiles of whole wheat kernels were the least attractive among test materials of wheat origin, whereas there were no significant differences among whole wheat flour, germ and endosperm. Wheat-germ extracts, however, were more attractive than were extracts of the other fractions. Whole millet flour or fermented millet flour volatiles were more attractive than those from whole millet kernels or millet starch. Beetles reached maximum responsiveness to grain volatiles 72-96 h after adult emergence. Groups of virgin females generally were more responsive than males or mixed-sex groups to the volatiles. ADDITIONAL ABSTRACT:A light-sensitive apparatus was used to record the olfactory responses of red flour beetle, T. castaneum. Wheat-germ volatiles from intact germ or solvent extracts were generally more attractive than volatiles of wheat endosperm or wheat bran. Whole millet flour or fermented millet flour volatiles were more attractive than those from whole millet kernels or millet starch
