An example of a piercing and sucking insect-pest of crops is a mealybug.
Mealybugs are small, soft-bodied insects that feed on plant sap using their piercing and sucking mouthparts. They are called mealybugs because they have a powdery, white, waxy coating that resembles meal. Mealybugs are found on a wide range of crops and ornamental plants, and they can cause significant damage by sucking the sap from the plant's tissues. They also secrete honeydew, a sweet, sticky substance that can promote the growth of sooty mold on plant surfaces.
In summary, mealybugs are a good example of a piercing and sucking insect-pest of crops due to their feeding behavior and the damage they can cause to plants.
