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.

对多数刺吸式昆虫而言，他们取食时会分泌胶状和水状两种唾液，其中胶状唾液会在取食早期分泌形成唾液鞘来围绕并保护口针，通过直接和间接的作用来帮助取食；而水状唾液中则包含了果胶酶、纤维素酶、多酚氧化酶、过氧化物酶、碱性磷酸酯酶、蔗糖酶等组分，来帮助刺吸式昆虫对植物穿刺、消化食物、解毒次生物质并破坏植物的防御反应。
