中文摘要：
【目的】 筛选出适合美国白蛾Hyphantria cunea大量饲养的人工饲料，提高饲养效果，为美国白蛾的人工繁育及实验种群建立奠定基础。【方法】 通过组建特定年龄生命表的方法，以复叶槭为对照，研究3种人工饲料对美国白蛾生长发育和种群增长趋势的影响。【结果】 3种人工饲料对美国白蛾的饲养效果具有明显差异。其中，以改良配制的饲料Ⅲ饲养效果最好，总发育历期[（45.91±0.41）d]、幼虫存活率(95.6%±0.6%）、老熟幼虫体长[（3.67±0.13）cm]及体重[（0.175
1±0.015 4）g]、新鲜蛹重[（0.151 1± 0.012 4）g]、成虫体长[♂（1.61±0.06）cm，♀（1.85±0.06）cm]和翅展[（♂（2.95±0.16）cm，♀（3.60± 0.19）cm）]、单雌平均产卵量[（265±46）粒]、种群发展趋势等生物学指标均优于另外两组。【结论】 综合相关生物学指标，饲料Ⅲ是饲养美国白蛾的适宜人工饲料。
英文摘要：
[Aim] This
study aims to identify the optimal artificial diet for Hyphantria cunea mass rearing, providing a basis for artificial
breeding and experimental population establishment for pest control research. [Methods]
An age-specific life table was used
to test the effects of three candidate artificial diets on H. cunea development, fecundity, and population growth potential.
The control group was reared on maple leaves. [Results] There was a significant difference between the
three artificial diets in the rearing effect of H. cunea. Of these, AD-Ⅲ was the most effective diet, with
developmental duration (45.91±0.41) d, immature survival rate 95.6%±0.6%, body
length (3.67±0.13) cm and body weight (0.175 1±0.015 4) g of older larvae,
fresh pupa weight (0.151 1±0.012 4) g, body length [♂ (1.61±0.06) cm; ♀ (1.85±0.06)
cm] and wingspan [♂ (2.95±0.16) cm; ♀ (3.60±0.19) cm] of adults, fecundity [265±46)/♀], and population development significantly
higher than in the AD-I and AD-Ⅱ groups. [Conclusion] AD-Ⅲ is the optimal artificial diet for
mass-rearing of H. cunea.
