| 中文摘要: |
| 研究测定了棉铃虫对 30种氨基酸、10种糖类和 4种棉花次生物质的取食选择性。结果显示初孵幼虫对0.1g/ml的L-苏氨酸、DL-2-氨基-n-丁酸、L-亮氨酸、L-缬氨酸、DL-瓜氨酸、L-丙氨酸、D-海藻糖、D-果糖以及棉花次生物质儿茶精、棉酚、槲皮素表现出较强的趋性反应 ,但将L-苏氨酸、L-亮氨酸、D-瓜氨酸、L-缬氨酸、L-苯丙氨酸以0.009g/ml的浓度、槲皮素和10种糖物质以0.025g/ml的浓度分别掺入人工饲料中,5日龄幼虫仅对D-海藻糖表现出高的取食选择性 |

| Preference of Helicoverpa armigera larvae to 30 amino acids, 10 sugars and 4 secondary substances of cotton was tested in laboratory. The results indicated that the neonates showed great taxis toward 0.1g/ml of L-threonine, acid DL-2-amino-n-butyric, L-leucine, L-valine, DL-citrulline, L-alanine, D-trehalose, D-fructose, catechin, gossypol, and quercetin. When 0.009 g/ml of L-threonine, L-leucine, DL-citrulline, L-valine, L-phenylanine, 0.025g/ml of quercetin and 10 sugars were supplemented into the artificial diets, the 5th day larvae just showed significant preference on D-trehalose. |
