Insects that pierce and suck on plants can be problematic in both nymph and adult stages.

Insects that pierce and suck on plants can be problematic in both nymph and adult stages.

• A. True
• B. False
• C. Only in larval stage
• D. Only after molting

Answer: (A)

Insects that pierce and suck plant sap use specialized mouthparts to access the plant’s fluids, and for many species, both immature nymphs and adults retain this feeding capability. Because both life stages can feed, they can each cause damage to the plant, leading to symptoms like leaf curl, yellowing, stunting, and the production of honeydew that fosters sooty mold. Additionally, nymphs often reproduce quickly and can establish populations rapidly, while adults can disperse to new plants, spreading the infestation. This combination means both stages contribute to the problem, so the statement is true.
