Ultrastructure and Transcriptome Analysis of the Larval Integument in Solitary and Gregarious Phases of Mythimna separata.

ABSTRACT: Mythimna separata larvae exhibit both solitary and gregarious phases under low and high population density, respectively; furthermore, differences in morphology, behavior and physiology have been observed in the two phases. The integument plays an essential role in the fitness, general metabolism, communication, and survival of insects; however, differences in the integument ultrastructure and gene expression in the solitary and gregarious phases are largely unknown. In this study, the integument ultrastructure of larvae in the solitary and gregarious phases was compared, and transcriptome analysis was conducted to identify which genes were differentially expressed in the two phases. The results showed that the gregarious larvae had thicker integuments and more polygonal particles o
