title: Enzymatic activity of aphroproteins.
abstract: Chitinase and proteinase activities were found in aphroproteins excreted by larvae of the cicada Aphrophora costalis Mats; this accounts for their fungicidal effect. Aphroproteins did not show DNase or RNase activities and did not exhibit properties of proteinase inhibitors. The data suggest that larval foam protects the larva and host plant from entomogenous and phytopathogenic fungi.
