Abstract: Gonocerus acuteangulatus (Goeze) (Hemiptera Coreidae) and Eurygaster maura (L.) (Hemiptera Scutelleridae) can cause detrimental effects on the yield quality of hazelnut and wheat, respectively, because of proteolytic enzymes injected into kernels via their saliva during the feeding activity. The research was carried out to develop an alternative rapid diagnostic method able to detect damage through the presence of bug proteinase in hazelnut and wheat kernels using biochemical markers; in particular, polyclonal antibodies against salivary glands of Leptoglossus occidentalis Heidemann (Hemiptera Coreidae) and of E. maura were assayed to detect saliva in bug-damaged nut and wheat kernels. The promising results achieved are showed and discussed.
