中文摘要：
【目的】 草地贪夜蛾Spodoptera frugiperda (J.E. Smith)是一种重要的农业害虫，于2019年1月侵入我国。室内大规模饲养可为草地贪夜蛾生物学等方面的研究提供材料。【方法】 本文制备草地贪夜蛾人工饲料，并比较草地贪夜蛾在人工饲料和天然食料上的生长发育和繁殖指标。【结果】 饲喂人工饲料和玉米叶的草地贪夜蛾幼虫存活率分别为86.33%和86.00%，幼虫历期为17.94 d和18.11 d。人工饲料饲养的草地贪夜蛾雌雄成虫寿命分别为13.92 d和12.00 d，而饲喂玉米叶的草地贪夜蛾雌雄成虫寿命分别为13.83 d和12.08 d。以人工饲料和玉米叶饲养的草地贪夜蛾平均单雌产卵量分别为943.50粒和885.42粒。【结论】 饲喂人工饲料和饲喂玉米叶的草地贪夜蛾幼虫的存活率、发育历期、雌雄虫寿命及单雌产卵量不存在显著差异，本研究配制的人工饲料可以用于草地贪夜蛾的大规模饲养。
英文摘要：
[Objectives] To assess the
feasibility of using an artificial diet to rear Spodoptera frugiperda, an
important agricultural insect pest that invaded to China in January 2019, for
study purposes. [Methods] We
compared the growth and reproduction of S. frugiperda fed either an artificial diet or
corn leaves. [Results] The survival of larvae fed on either the artificial
diet or corn leaves were 86.33% and 86.00%, respectively, and the durations of
the larval periods of larvae raised on these foods were 17.94 d and 18.11 d,
respectively. The longevity of male and female adults reared on the artificial diet was
13.92 d and 12.00 d, respectively, compared to
13.83 d and 12.08 d for those reared on corn. The average number of eggs laid
by females raised on the artificial diet and those raised on corn leaves was
943.50 and 885.42, respectively. [Conclusion] There was no significant difference in the
growth, development and reproduction of S. frugiperda raised on an artificial diet compared to those raised on corn leaves.
The artificial diet is suitable for mass rearing S. frugiperda for research purposes.
