Which statements about aphids are true?

• A. Slow moving, soft bodied insects with tailpipes; They inject saliva into plants as they feed; Some may transmit viruses.
• B. They are large, hard-bodied insects that chew holes in leaves.
• C. They feed only at night and do not transmit viruses.
• D. They are beneficial pollinators.

Answer: (A)

Aphids are small, slow-moving, soft-bodied insects with tailpipes called cornicles on their rear. They feed by piercing plant tissues with slender mouthparts and sucking the sap, and they secrete saliva as they feed to access the phloem. This feeding process, along with their tendency to multiply on new growth, makes them effective vectors for plant viruses, so some aphids can transmit viruses to ornamental plants. The other descriptions don’t fit aphids: they are not large, hard-bodied insects that chew holes, they don’t feed only at night, and they are not beneficial pollinators.
