Erythrina velutina vicilin, EvV, is a dimeric glycoprotein with Mr of 124.6 kDa. EvV was tested for anti-insect activity against bean bruchid larvae. EvV had LD(50) of 0.10% and ED(50) of 0.14% for Z. subfasciatus and LD(50) of 0.26% and ED(50) of 0.19% for C. maculatus. EvV was not digested by bean larvae enzymes until 12 h of incubation, and at 24 h EvV was more resistant to Z. subfasciatus enzymes.
绒毛刺桐豌豆球蛋白（EvV）是一种二聚体糖蛋白，分子量为124.6 kDa。对EvV针对菜豆象幼虫的抗虫活性进行了测试。EvV对亚褐豆象的半数致死剂量（LD50）为0.10%，半数有效剂量（ED50）为0.14%；对黄斑豆象的LD50为0.26%，ED50为0.19%。在孵育12小时之前，EvV未被豆象幼虫的酶消化，在24小时时，EvV对亚褐豆象的酶更具抗性。
