Which pest is associated with sucking sap from plants?

Aphids are small, soft-bodied insects known for their feeding habits, which involve piercing plant tissues to access and suck the sap from plants. This sap is rich in nutrients and serves as a food source for aphids. Their feeding can lead to significant damage to plants, resulting in stunted growth, yellowing of leaves, and even plant death in severe cases. Additionally, aphids can also transmit plant viruses, further complicating plant health issues.

In contrast, the other options have different feeding behaviors that do not primarily involve sucking sap. For example, brown marmorated stink bugs and caterpillars have various other feeding methods, such as consuming whole leaves or fruits, whereas wireworms are the larval stage of click beetles and feed primarily on roots and tubers.
