Five flavonoids from hops, two of their derivatives, along with naringenin used as a model compound, were tested for their antifeedant activity against three coleopteran stored product pests: Sitophilus granarius L., Tribolium confusum Duv. and Trogoderma granarium Everts. The introduction, into the tested flavonoid molecules, of additional structural fragments such as prenyl or dimethylpyran moiety, is proposed to significantly alter the deterrent activity of the compounds. The prenyl moiety in flavonoids increased the deterrent activity of these compounds in all three of the grain feeding species used in the tests. It is also concluded that the introduction of dimethylpyran moiety to the flavonoid structure increases its deterrent activity in S. granarius and T. confusum, but in one of the test insects, T. granarium, an increased feeding was observed in response to the introduction of dimethylpyran moiety to the flavonoid structure.
对啤酒花中的五种黄酮类化合物、它们的两种衍生物以及用作模型化合物的柚皮素，针对三种鞘翅目仓储害虫进行了拒食活性测试，这三种害虫分别是谷蠹（Sitophilus granarius L.）、杂拟谷盗（Tribolium confusum Duv.）和赤拟谷盗（Trogoderma granarium Everts）。研究提出，在受试黄酮类化合物分子中引入异戊烯基或二甲基吡喃部分等额外结构片段，会显著改变这些化合物的驱避活性。黄酮类化合物中的异戊烯基部分增强了这些化合物对测试中使用的所有三种谷物取食物种的驱避活性。研究还得出结论，在黄酮类化合物结构中引入二甲基吡喃部分会增强其对谷蠹和杂拟谷盗的驱避活性，但在其中一种受试昆虫赤拟谷盗中，观察到在黄酮类化合物结构中引入二甲基吡喃部分后其取食量增加。
