A digestive tract expressing α-amylase influences the adult lifespan of Pteromalus puparum revealed through RNAi and rescue analyses.

PpAmys probably have roles in carbohydrate metabolism of P. puparum and its host/parasitoid relationships. The characterization and functional study of PpAmys lays the foundation for the protection and utilization of parasitoid resources, and the biological control of agricultural pests. © 2019 Society of Chemical Industry.
