Identification of azukisapogenol triterpenoid saponins from <i>Oxytropis hirta</i> Bunge and their aphicidal activities against pea aphid <i>Acyrthosiphon pisum</i> Harris

Abstract

Azukisapogenol triterpenoid saponins from O. hirta could be used as biopesticides to control aphids for their multiple efficacies, including oral toxicity, deterrent activity, and reproduction inhibitory activity. The toxic symptoms involved insect body-color changes. Midgut tissues and their related enzymes were the targets for saponins showing aphicidal activities. © 2022 Society of Chemical Industry.
