Which of the following insects is primarily known to damage corn plants?

Caterpillars are primarily known to damage corn plants as they are the larval stage of various moth species, some of which are significant pests in corn production. One of the most notorious caterpillars affecting corn is the corn earworm, which feeds on the ears of the corn and can cause extensive damage to both the developing kernels and the overall health of the plant. Other caterpillar species, such as the fall armyworm, also target corn, leading to reduced yields and crop quality.

The eating habits of caterpillars, being voracious feeders, result in visible damage, such as leaf loss and the potential introduction of diseases, which can further impact crop productivity. Understanding which insects pose the greatest threat to corn is crucial for effective pest management strategies in agriculture.
