The Allatoregulatory Neuropeptides and their Genes in the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)
The genes encoding the S. frugiperda allatotropin (Spofr-AT), allatostatin (Spofr-AST), allatostatin type-A (Spofr-AST A) peptide family and allatotropin 2 (Spofr-AT 2) peptides were isolated from S. frugiperda brain cDNA. The Spofr-AT gene is expressed in three mRNA isoforms with 134, 171, and 200 …
