Genomic and Transcriptomic Analysis Reveals Cuticular Protein Genes Responding to Different Insecticides in Fall Armyworm Spodoptera frugiperda.

ABSTRACT: The fall armyworm (FAW), Spodoptera frugiperda, is a serious pest of crucial crops causing great threats to the food security of the world. It has evolved resistance to various insecticides, while the underlying molecular mechanisms remain largely unknown. Cuticular proteins (CPs), as primary components in cuticle, play an important role in insects' protection against environmental stresses. Few of them have been documented as participating in insecticide resistance in several insect species. In order to explore whether CP genes of the FAW exhibit a functional role in responding to insecticides stress, a total of 206 CPs, classified into eight families, were identified from the genome of the FAW through a homology-based approach coupled with manual efforts. The temporal expression p
