Salivary gland histology of the larva red palm weevil, Rhynchophorus ferrugineus (coleoptera: dryophthoridae)

Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier 1790) is a very destructive phytophagous insect pest to plants under family Arecaceae. The remarkable abilities of RPW to destroy the host plant have been attributed to its feeding behaviors and the functions of the salivary gland. The study...
