True or False: All aphids suck plant juices from stems and leaves.

The statement is true because all aphids are known for their feeding behavior of sucking plant juices, which is a characteristic trait of this pest family. Aphids are small, soft-bodied insects that primarily feed on the sap of plants. They have specialized mouthparts, called stylets, that allow them to penetrate plant tissues and extract the nutrient-rich fluids. This feeding can lead to a variety of plant health issues, including yellowing leaves, stunted growth, and the potential for transmitting plant viruses.

While there is a diversity of aphid species, they all share this common feeding behavior. Understanding this is crucial for managing aphid populations effectively in both ornamental and turf applications. Other options might suggest discrepancies in feeding behavior based on species or life cycle stages, but they overlook the fundamental biology of aphids that unites them in their feeding habits.
