Question: 1 / 400

What insect is commonly associated with the damage it does to crops and is often depicted in educational materials?

Spider

Aphid

The aphid is a small, sap-sucking insect that is commonly associated with significant damage to a variety of crops. It feeds by inserting its mouthparts into plant tissues and extracting fluids, which can lead to stunted growth, leaf curling, and even plant death in severe infestations. Aphids are known for their rapid reproduction rates, allowing populations to explode quickly under favorable conditions, making them a common concern for farmers and crop consultants.

In educational materials, aphids are often depicted due to their economic impact and the role they play as vectors for plant diseases, which can further exacerbate crop loss. They are also recognizable and prevalent across different crops, which makes them a prime subject for study and discussion in crop management practices. Their significance in integrated pest management strategies is also a reason for their frequent mention in educational contexts.
