This endoparasitoid wasp peptide has a role in disruption of the cellular host immune response, since it reduces the capacity of D.saccharalis hemocytes to encapsulate foreign bodies. On the other hand, it shows no effect on the humoral immune response, since it has no effect on phenoloxidase activity. Expressed by the venom duct. The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. Potential candidate for insect pest control through ingestion. Feeding leaves coated with this peptide to neonate D.saccharalis result in increased mortality and significantly reduced feeding compared to caterpillars fed untreated leaves. Highly abundant in venom.
