What are common signs of insect infestation?

• A. Presence of weeds
• B. Wilting and healthy growth
• C. Visible insects and damaged plants
• D. Soil temperature changes

Answer: (C)

Visible insects and damaged plants are prominent indicators of insect infestation. When plants are being attacked by insects, you may notice the pests themselves, such as aphids, mites, or caterpillars, on the foliage or stems. Additionally, signs of damage caused by these insects can include chewed leaves, holes, or discoloration, which can lead to wilting, stunted growth, or even the death of plants.

Identifying both the presence of insects and any associated plant damage is critical for effective pest management. Early detection through these visible signs can allow for prompt action to mitigate the problem, protecting the health of the plants and ensuring a thriving garden or crop.

The other options do not directly indicate insect infestation. Weeds, while they can affect plant health, are not a direct sign of insect activity. Wilting in healthy growth can be caused by a range of environmental factors rather than invasive pests. Soil temperature changes can influence plant health indirectly but are not a clear indication of insect presence. Thus, the presence of visible insects and damaged plants is the most reliable sign of infestation.
