What is a typical symptom of a plant infested with aphids?

A typical symptom of a plant infested with aphids includes curling leaves and the presence of sticky honeydew deposits. Aphids, being sap-sucking insects, feed on the plant's juices, which can cause the leaves to curl or distort as they react to the feeding damage. The honeydew is a sugary substance excreted by the aphids as they consume the sap, which can lead to the growth of sooty mold if it lands on other plant surfaces. This sticky residue can also attract other pests and create further issues for the plant.

The other symptoms listed do not specifically indicate an aphid infestation. Drooping branches and yellowing leaves can be symptoms of various environmental stressors or nutrient deficiencies, fragrant blooms and rapid growth typically signify healthy plants, and wilting roots and sparse foliage may be indicators of root issues or other pest problems unrelated to aphids. Understanding these symptoms can help in identifying and managing pest issues effectively.
