研究了37种黄酮类化合物（9种黄酮、18种黄酮醇、8种二氢黄酮和2种二氢黄酮醇）对粘虫（Mamestra configurata步行者; BAW）取食选择的影响。饲养选择取决于生化结构的细微差异。未取代黄酮和黄烷酮是最强的摄食抑制剂，而7，4 '-二羟基黄酮和二氢槲皮素则刺激BAW摄食。甘蓝型油菜的组成型黄酮类化合物异鼠李素-3-槐糖苷-7-葡萄糖苷和山奈酚-3，7-二葡萄糖苷在高于内源水平的浓度下补充时是有效的阻遏物。在无选择的生物测定中，黄酮降低幼虫重量以及幼虫和蛹的发育时间。
Thirty-seven flavonoid compounds ( 9 flavones, 18 flavonols, 8 flavanones, and 2 flavanonols) were investigated for their effect on feeding choice with bertha armyworm ( Mamestra configurata Walker; BAW). Feeding choice was dependent upon subtle differences in biochemical structure. Unsubstituted flavone and flavanone were the strongest feeding deterrents in the choice bioassay, while 7,4'-dihydroxyflavone and dihydroquercetin stimulated BAW to feed. The constitutive flavonoids of Brassica napus, isorhamnetin-3-sophoroside-7-glucoside and kaempferol-3,7-diglucoside, were effective deterrents when supplemented at concentrations higher than endogenous levels. In a no-choice bioassay, flavone reduced both larval weight as well as larval and pupal development time.
