What is a common symptom of pest damage in plants?

Leaf discoloration is a common symptom of pest damage in plants because many pests, such as aphids, spider mites, and whiteflies, feed on plant sap or tissues, leading to nutrient deficiencies and stress responses in the plant. As a result, leaves may exhibit yellowing (chlorosis) or other color changes due to disrupted photosynthesis and impaired chlorophyll production.

Additionally, certain pests can introduce toxins or pathogens that impact leaf health, further contributing to discoloration. In contrast, excessive growth, increased flowering, and heightened resilience might indicate other factors at play, such as optimal environmental conditions or beneficial influences, rather than a direct response to pest damage.
