摘　　要：利用叶碟法在室内测定了棉铃虫对人类酸、甜、苦、咸4种基本呈味物质和麻、辣味2种植物提取物的取食反应。正交试验结果表明,棉铃虫幼虫对用甜味、苦味和辣味物质(蔗糖、奎宁和辣椒提取物)处理过的烟叶取食选择率较高,对这3种呈味物质表现出有较好的适应性;而幼虫对咸味、酸味和麻味物质(氯化钠、柠檬酸和花椒提取物)处理过的烟叶取食量较少,这3种呈味物质表现出较强的拒食活性。在选择性条件下,幼虫的取食量与花椒提取物剂量显著相关;而在非选择性条件下,幼虫的取食量与氯化钠剂量显著相关。Feeding responses of Helicoverpa armigera larvae to citric acid,sucrose,quinine and NaCl respresenting 4 basic human taste materials of sour,sweet,bitter and salty,and 2 plant extracts of numb,piquancy taste,were tested in the laboratory by leaf-disc method. Orthogonal experimental results showed that the selection percentages of bollworm feeding on tobacco leaves treated with sweet,bitter and piquancy taste compounds （ sucrose,quinine and extract of Capsicum annuum） were higher,indicating the larvae had the better adaptability to sweet,bitter,and piquancy taste compounds. In contrast,the feeding amount of bollworm larvae on tobacco leaves treated with salty,sour,and numb taste compounds （ NaCl,citric acid,and extract of Zanthoxylum bungeanum） was less. The taste compounds of salty,sour,and numb had very strong antifeedant activity on bollworm larvae. The feeding amount of larvae was closely related to the doses of Z. bungeanum extract in the choice bioassay,whilst it was related to NaCl dosages in non-choice bioassay.
