Which pest is associated with honeydew production and can lead to sooty mold?

• A. Aphids
• B. Euonymus scale
• C. Whiteflies
• D. Spider mites

Answer: (A)

Honeydew is a sugary liquid excreted by sap-sucking insects as they feed on phloem. This sticky substance sits on leaf surfaces and becomes a food source for sooty mold, a black fungus that coats leaves and reduces light for photosynthesis. Aphids are especially known for producing large amounts of honeydew because they breed rapidly and form sizeable colonies on new growth. That heavy honeydew deposition creates ideal conditions for sooty mold to take hold on ornamental plants. While other sap-sucking pests like whiteflies or scale can also produce honeydew, aphids are the classic culprits linked to visible sooty mold on ornamentals.
