Leafhoppers, Planthoppers, and Cicadas: Xylem-Feeding Insects

Which insects feed on xylem sap?

a) Only Leafhoppers

b) Only Planthoppers

c) Only Cicadas

d) Planthoppers and Leafhoppers

e) Leafhoppers, Planthoppers, and Cicadas

Answer:

Leafhoppers, Planthoppers, and Cicadas.

Leafhoppers, Planthoppers, and Cicadas are insects that feed on xylem sap. These insects have specialized mouthparts that allow them to pierce the xylem vessels of plants and extract the sap. This feeding behavior can potentially damage the plants by disrupting the flow of water and nutrients.

Xylem is a type of plant tissue responsible for transporting water and nutrients from the roots to the rest of the plant. Insects like Leafhoppers, Planthoppers, and Cicadas have adapted to feed on this xylem sap as a food source.

By tapping into the xylem vessels, these insects can access the essential water and nutrients being transported within the plant. However, their feeding activity can lead to negative impacts on plant health and growth.
