Responses by five species of cucujid grain beetles (mixed-sex adults) to various volatiles were assessed by means of a two-choice, pitfall olfactometer. The test volatiles were short-chain alcohols and ketones known to be produced by fungi. Both racemic and chiral 1-octen-3-ols were strong attractants forCryptolestes ferrugineus (Stephens), as had been found previously forOryzaephilus surinamensis (L.),O. mercator (Fauvel), andAhasverus advena (Waltl). 3-Methylbutanol was another good attractant for these four cucujids, and it was the only test compound to whichCathartus quadricollis (Guér.) responded positively. 1-Octen-3-one, racemic 3-octanol, and 3-octanone showed various degrees of attractiveness for the former four species of cucujids.O. surinamensis was the only species of test beetle to show much positive response to 2-phenylethanol and ethanol. ForO. mercator andO. surinamensis, 3-methylbutanol enhanced positive response to their respective cucujolide aggregation pheromones.
五种丽金龟(雌雄混合成虫)对各种挥发物的反应通过双选择陷阱嗅觉仪进行了评估。测试挥发物是短链醇和酮,已知这些物质是真菌产生的。此前已发现外引米象(Oryzaephilus surinamensis(L.))、褐赤拟谷盗(O. mercator(Fauvel))和黑毛皮蠹(Ahasverus advena(Waltl))对顺式和手性 1-辛烯-3-醇有很强的吸引力,而 3-甲基丁醇也是这四种丽金龟的另一种良好引诱剂,而且它是唯一对 Cathartus quadricollis(Guér.)有积极反应的测试化合物。1-辛烯-3-酮、外消旋 3-辛醇和 3-辛酮对前四种丽金龟表现出不同程度的吸引力。在测试的丽金龟中,只有外引米象对 2-苯乙醇和乙醇表现出较强的正反应。对于褐赤拟谷盗和外引米象,3-甲基丁醇增强了它们各自的丽金龟醇聚集信息素的正反应。
