The sawtoothed grain beetle,Oryzaephilus surinamensis (L.) (Coleoptera: Cucujidae), is attracted to certain volatile components that occur in whole and rolled oats as determined by a laboratory pitfall chamber bioassay. More than 100 components were detected in the attractive carbonyl-containing fractions; 14 of these, making up 60% of the total, were identified and bioassayed. Although hexanal, heptanal, octanal, (E)-2-heptenal, and 2-furaldehyde, at doses ranging variously from 1 to 100 μg, were all significantly attractive, only 1 /10 to 1 /100 as much (E)-2-nonenal or (E,E)-2,4-nonadienal was necessary to produce comparable insect response. In addition, propanal and formaldehyde (previously reported in oats but not detected by us) were bioassayed and found to be attractive.
锯齿谷盗，Oryzaephilus surinamensis（L.）（鞘翅目：象甲科），会被整粒和轧碎的燕麦中某些挥发性成分吸引，这是通过实验室陷阱室生物测定法确定的。在有吸引力的含羰基部分中检测到了 100 多种成分；其中 14 种占总成分的 60%，并进行了鉴定和生物测定。虽然正己醛、庚醛、辛醛、（E）-2-庚烯醛和 2-糠醛，在 1 至 100 μg 的不同剂量下，均具有显著的吸引力，但（E）-2-壬烯醛或（E，E）-2,4-壬二烯醛只需 1/10 到 1/100 的量就足以产生类似的昆虫反应。此外，丙醛和甲醛（以前在燕麦中报道过，但我们没有检测到）也进行了生物测定，发现它们具有吸引力。
