中文摘要：
【目的】 草地贪夜蛾Spodoptera frugiperda（J.E. Smith）是2019年入侵我国的重要农业害虫，对我国玉米等粮食作物生产构成严重威胁。为了明确草地贪类型夜蛾在不同玉米上的生物学特性，为不同类型玉米上草地贪夜蛾的防控提供参考。【方法】 本文研究了苗期不同类型玉米（甜玉米、糯玉米、甜糯玉米和普通玉米）对草地贪夜蛾的生长发育与繁殖的影响。【结果】 草地贪夜蛾在玉农科糯、斯达206、南甜糯601、焦点玉501的发育历期和存活率均无显著差异，平均发育历期为17.88-18.81 d，平均存活率为70.1%-76.3%。幼虫期取食玉农科糯、斯达206、南甜糯601、焦点玉501的草地贪夜蛾蛹重、蛹历期、成虫寿命和单雌产卵量在不同类型玉米间无显著差异，其中平均雌蛹重为193.67-214.16 mg/头，平均雄蛹重为197.40-200.41 mg/头，雌蛹平均历期为8.8-9.2 d，雄蛹平均历期为9.4-10.1 d，雌蛾平均寿命为11.0- 16.1 d，雄蛾平均寿命为9.8-13.1 d，平均单雌产卵量分别为733.3-845.2粒。【结论】 苗期4种不同类型玉米（玉农科糯、斯达206、南甜糯601、焦点玉501）对草地贪夜蛾的生长发育与繁殖无显著影响。
英文摘要：
[Objectives] To improve
understanding of the biological characteristics of the fall armyworm, Spodoptera frugiperda (J.E. Smith), an
important agricultural pest that invaded China in 2019 and now seriously
threatens maize and other food crops, and thereby provide a reference for the
prevention and control of this pest. [Methods] The growth, development
and reproduction of S. frugiperda on
four different maize varieties; sweet maize (Sida206), waxy maize
(Yunongkenuo), sweet waxy maize (Nantiannuo601) and conventional maize
(Jiaodianyu501) were investigated during the seedling stage. [Results] The developmental duration and survival
rate of S. frugiperda raised on each of the four maize
varieties did not differ significantly; the average development duration was
17.88-18.81 d, and the average survival rate was 70.1%-76.3%. Nor did maize
variety significantly affect pupal weight, pupal duration, adult longevity or
the number of eggs per female; the average female and male pupal weights were
193.67-214.16 mg and 197.40-200.41 mg, respectively, the average female and
male pupal durations were 8.8-9.2 d and 9.4-10.1 d, respectively, the average
longevity of female and male adults was 11.0-16.1d and 9.8-13.1 d,
respectively, and the average number of eggs per female was 733.3-845.2. [Conclusion] These results suggest that the growth,
development and reproduction of S. frugiperda is essentially the same irrespective of which of four different maize varieties
(Sida206, Yunongkenuo, Nantiannuo601 and Jiaodianyu501) larvae feed on during
the seedling stage.
