中文摘要：
【目的】 以甜菜夜蛾Spodoptera exigua（Hübner）为研究对象，优化饲料配方筛选，为室内饲养甜菜夜蛾提供参考。【方法】 选取6组人工饲料（配方1、2、3、4、5和6）饲喂甜菜夜蛾幼虫，分别记录不同饲料对其死亡率和产卵量的影响，以及甜菜夜蛾幼虫对不同配方的饲料利用率和营养指标等差异。【结果】 以配方3饲喂的甜菜夜蛾幼虫死亡率最低、产卵量最高，且试虫对配方3的饲料利用率最高。【结论】 通过本实验筛选获得以兔粮和小麦胚芽片为主要营养成分的甜菜夜蛾人工饲料配方一种，为后续室内高效、便捷和省时省料饲养甜菜夜蛾提供一定借鉴。
英文摘要：
[Objectives] To develop a better artificial diet for Spodoptera exigua (Hübner) and thereby improve the captive rearing of this pest. [Methods] Six different artificial diets (1, 2, 3, 4, 5 and 6) were fed to S. exigua larvae, and their effects on larval mortality and adult egg production, as well as differences their utilization rate and nutritional indicators, were compared. [Results] Larvae fed formula 3 had the lowest mortality, the highest utilization rate and adult egg production. [Conclusion] Formula 3, which was mainly comprised of rabbit pellets and wheat germ, can improve the cost-effectiveness of rearing S exigua in captivity.
