在原有饲料配方的基础上，通过添加适宜浓度的辣椒粉作为取食刺激剂及去除原饲料配方中的番茄酱组分，作者对烟青虫Helicoverpa

assulta (Guenée)幼虫的人工饲料进行了改进研究。测定了6种人工饲料对烟青虫生物学参数、营养指标和生命表参数的影响。结果表明，与

取食对照饲料相比，取食添加3%番茄酱的饲料后，烟青虫的幼虫历期、蛹重和生殖力无显著差异。在试验浓度内，取食添加辣椒粉的饲料后烟

青虫幼虫存活率、幼虫相对取食量和蛹重均显著高于取食对照饲料的相应指标。但饲料中辣椒粉浓度达到或超过2%时烟青虫幼虫的消化能力降

低，达到4%时成虫交配力显著降低。在6种供试饲料中，配方Ⅱ即添加1%辣椒粉的饲料为最佳配方饲料，与取食其他饲料相比，取食配方Ⅱ饲

料后烟青虫生殖力和内禀增长率均显著提高。改进的人工饲料可大量饲养烟青虫以满足室内试验及工厂化生产核多角体病毒的需要。

Based on the original artificial diet formulation, an improved artificial diet for Helicoverpa assulta (Guenée) larvae was

developed by incorporating a proportion of chili powder as a feeding stimulant, and removing the tomato paste included in

the original diets. The effects of six artificial diets on biological parameters, nutritional indices and life table

parameters of H. assulta were investigated. The results indicate that there was no significant difference between an

artificial diet with 3% tomato paste and the control diet with respect to larval developmental period, pupa weight and

fecundity. However, larvae fed the artificial diet containing chili powder (from 05% to 4% wet weight) had significantly

higher survival rate, relative consumption rate and pupal weight than those on the control diet. The digestion of H. assulta

larvae was inhibited by the addition of ≥ 2% chili powder and adult mating ability significantly decreased when fed a diet

containing 4% chili powder. The optimum formulation was the control diet plus 1% chili powder. H. assulta fed on this diet

exhibited significantly higher fecundity and intrinsic rate of increase than those fed on other diets. The improved

artificial diet was suitable for rearing H. assulta in the laboratory and mass rearing for the commercial production of

nuclear polyhedrosis H. assulta viruses.
