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.
研究了37种黄酮类化合物(9种黄酮、18种黄酮醇、8种黄烷酮和2种二氢黄酮醇)对甜菜夜蛾(Mamestra configurata Walker;BAW)取食选择的影响。取食选择取决于生化结构的细微差异。在选择生物测定中,未取代的黄酮和黄烷酮是最强的取食抑制剂,而7,4'-二羟基黄酮和二氢槲皮素刺激甜菜夜蛾取食。甘蓝型油菜的组成型黄酮异鼠李素-3-槐糖苷-7-葡萄糖苷和山奈酚-3,7-二葡萄糖苷,在高于内源性水平的浓度下补充时是有效的抑制剂。在无选择生物测定中,黄酮降低了幼虫体重以及幼虫和蛹的发育时间。
