Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle

open access: yesIntegrative Zoology, EarlyView.
Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.
