For most piercing-sucking insects, they will secrete gell saliva and watery saliva when they feed on plants. The gell saliva will be secreted at the early stage of feeding to form salivary sheath, which is supposed to surround and protect the stylet. This saliva can help piercing-sucking insects to feed on plants directly and indirectly. Meanwhile, the watery saliva contains many components like pectnase, cellulose, polyphenol oxidase, peroxidase, alkaline phosphatase, sucrase, etc. These components can help piercing-sucking insects in plant tissue penetration, food digestion, detoxification of plant secondary substances and break-down of plant defence reaction.
