Olfactory responses of 72- to 96-hr-old, 24-hr starved adult male, female, or mixed-sex groups of the red flour beetle,Tribolium castaneum (Herbst), to volatiles from wheat and millet kernels, certain milled fractions, and solvent extracts were recorded by using a lightsensitive 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 by 72-96 hr after adult ecdysis. Groups of virgin female beetles generally were more responsive than male or mixed-sex groups to volatiles of substances tested.
用感光装置记录了 72 至 96 小时龄、24 小时禁食的雄性、雌性或混合性别的红面粉甲虫(Tribolium castaneum( Herbst))对来自小麦和小米颗粒、某些磨碎的颗粒以及溶剂提取物的挥发物的嗅觉反应。完整胚芽或溶剂提取物的小麦胚芽挥发物通常比小麦胚乳或麦麸的挥发物更具吸引力。在来自小麦的测试材料中,整个麦粒挥发物最不具吸引力,而全小麦粉、胚芽和胚乳之间没有明显差异。然而,小麦胚芽提取物比其他部分的提取物更具吸引力。整粒小米粉或发酵小米粉的挥发物比整粒小米或小米淀粉的挥发物更具吸引力。蜕皮后 72-96 小时,成虫对谷物挥发物的反应达到最大值。处女雌性甲虫群体通常比雄性或混合性别的群体对测试物质的挥发物更敏感。
