Which pest is identified by a pear-shaped body?

• A. Mealybugs
• B. Whiteflies
• C. Thrips
• D. Aphids

Answer: (D)

Recognizing body shape helps you identify pests quickly in a greenhouse setting. Aphids have a soft, pear-shaped body that is often visible in clusters on new growth. Many aphid species present a rounded rear with small cornicles (tiny tail-like tubes) protruding from the abdomen, and they can be either wingless or winged. This pear-shaped form sets them apart from a few other common greenhouse pests: mealybugs are covered in a waxy, cottony coating and look more oval and fuzzy; whiteflies are tiny insects with white wings and they tend to fly up when the plant is disturbed; thrips are long, slender insects with narrow bodies and fringed wings. So, when you see a pear-shaped, soft-bodied insect densely on new shoots, aphids are the best match. This identification often comes with honeydew and possible sooty mold, plus ants farming the colonies, which further supports aphids as the culprit. Use this cue to guide scouting and management decisions, such as deploying appropriate biological controls or cultural practices to reduce aphid numbers.
