Functional analysis of serine protease EfSP1 in Eocanthecona furcellata Wolff (Hemiptera: Pentatomidae)

Serine protease is an important digestive enzyme involved in many physiological and biochemical reactions, including digestion of insect food protein, blood coagulation, signal transduction, immune response, and hormone activation. The physiological functionality of salivary gland serine protease EfSP1 in the predatory natural enemy Eocanthecona furcellata is unknown. As a salivary gland protein, EfSP1 may have insecticidal activity against the prey Spodoptera frugiperda.
