中文摘要:
      草地贪夜蛾是2019年新入侵我国的重大农业害虫,对我国粮食生产安全构成了严重威胁。本文在室内条件下,观察记录了雌成虫的产卵节律及其对不同介质的产卵选择性。结果表明,草地贪夜蛾平均最高日产卵量可达229.3粒/头,且主要集中在羽化后7 d内产卵,占总产卵量的68.1%;产卵主要在20:00-05:00进行;在玉米老叶和牛皮纸上的产卵量显著高于玉米心叶、复印纸、玻璃壁和棉花等介质上的产卵量,分别占总产卵量的32.6%和31.1%。这些结果表明,草地贪夜蛾成虫具有较强的繁殖能力和产卵节律性,对玉米老叶片具有显著的产卵偏好。
英文摘要:
      The fall armyworm, Spodoptera frugiperda, is a notorious agricultural pest which newly invaded into China in 2019. It would pose a serious threat to the production of grain in our country. The oviposition rhythms of S.frugiperda female adult and its oviposition preferences to different medium were observed indoor. The results showed that the highest daily fecundity was 229.3 eggs per individual, and most eggs were laid in 7 days after emergence, account to 68.1% of the total eggs. Furthermore, females mainly laid eggs during 20:00-05:00. The eggs laid on developed maize leaf and craft paper were significantly more than those on first fully expanded leaf, printer paper, glass, and cotton ball, account to 32.6% and 31.1% of the total eggs, respectively. All these results indicated that the adults of S.frugiperda have a greater reproduction capacity and an obvious oviposition rhythm, as well as a greater oviposition preference to developed maize leaves.
