Abstract：
[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.
