Which of the following is a common pest that affects crops?

Aphids are commonly recognized as significant pests that affect a wide variety of crops. These small, sap-sucking insects can cause considerable damage to plants by feeding on their juices, which can stunt growth, reduce yields, and even lead to plant death in severe cases. Additionally, aphids can transmit plant viruses, further exacerbating their negative impact on agricultural production.

In contrast to aphids, ladybugs are beneficial insects that feed on aphids and other pests, making them allies in pest control rather than threats to crops. Grasshoppers can also be pests, but their impact is often more variable and context-dependent, depending on species and population levels. Honeybees play a crucial role in pollination, which contributes positively to crop production rather than posing any direct threat as pests do. Thus, aphids stand out as the most commonly recognized pest in the context of crop damage, reinforcing their significance in agricultural studies.
