Effects of a chitin binding vicilin from Erythrina velutina seeds on bean bruchid pests (Callosobruchus maculatus and Zabrotes subfasciatus).Protein Pept Lett. 2008; 15(3):270-4.PP
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.
