Abstract:

Spodoptera furgiperda is a major invading pest. In the south of China, S. furgiperda can survive and multiply through whole year. Previous investigations and research revealed the risk that wheat was overwintering host of S. furgiperda. To investigate the internal mechanism of feeding fitness of S. furgiperda to wheat, transcriptomes of S. furgiperda larva feeding on corn, wheat and artificial diet were sequenced and compared. Totally, 66407 unigenes were obtained after assembly and 18868 unigenes were functionally annotated. Respective 542 and 6863 differentially expressed genes were found in wheat-feeding larva and artificial-diet-feeding larva, comparing with corn-feeding larva. Analysis of differentially expressed genes showed that lots of cuticle-related genes up regulated in wheat-feeding larva, while down regulated in artificial-diet-feeding larva. Cytochrome P450 genes were found down regulated in both wheat-feeding and artificial-diet-feeding larva. This study provides information and reference to risk assessment that S. furgiperda damage wheat through overwintering stage.
