[The effects of Sophora alopecuroids alkaloids on metabolic esterases of the diamond-back moth]
Acta Entomologica Sinica 46 (1), 122-125
Abstract: The effects of seven alkaloids from Sophora alopecuroids, a leguminous plant, on metabolic esterases of the larvae of the diamondback moth Plutella xylostella (L. ) were studied. The results indicate that cytisine and aloperine could inhibit carboxylesterase activity through non-competitive inhibition. Sophoramine, saphoradine, matrine, oxymatrine and cytisine could inhibit the activity of acid phosphoresterase, and cytisine could also weakly inhibit the activity of alkaline phosphoresterase. In addition, three alkaloids, cytisine, sophramine and sophocarpine could inhibit the. activity of glutathione-s-transferase in diamondback moth larvae.
