Amino acid, fatty acid, and carbohydrate metabolomic profiles with ginsenoside-induced insecticidal efficacy against Ostrinia furnacalis (Guenee)

ConclusionsPDS decreased the consumption index, relative growth rate, approximate digestibility, conversion of ingested and digested food in 3rd instar larvae of O. furnacalis in a dose-dependent manner. PDS decreased 15 free amino acids, 16 free fatty acids, and 5 carbohydrates and increased the levels of palmitoleic acid, palmitic acid, and 9-octadecenoic acid in 3rd instar larvae. The activity of detoxification-related enzymes, such as AChE, GST, CYP540, CarE, TH, ACP and ALP, was reduced in a dose-dependent manner in 3rd instar larvae exposed to PDS. These data confirmed the inhibitory effect of PDS against growth, food utilization and detoxification in 3rd instar larvae of O. furnacalis as well as the potential for using PDS as an efficient tool for insect pest management for O. furnacalis larvae.
