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

These findings indicate that EfSP1 is involved in the growth, development, and predation of E. furcellata. As a salivary gland protein, EfSP1 also has insecticidal activity, affecting the growth and development, chitin metabolism, trehalose metabolism, and humoral immunity of S. frugiperda. These findings reveal the physiological function of EfSP1. © 2025 Society of Chemical Industry.
