Which pest is known for causing ear drop in corn?

The European corn borer is recognized for causing ear drop in corn primarily due to its feeding habits during the larval stage. This pest infests the ears and ears' shanks as it develops, leading to structural damage. The feeding can weaken the attachment of the ear to the plant, making it prone to dropping from the stalk before harvest. As a result, the reduced yield and quality can have significant economic impacts on corn production.

Additionally, the European corn borer has a history of being a major pest in various corn-growing regions, and its lifecycle aligns with critical corn developmental stages. Identification and management of this pest are essential to minimize its effects, including ear drop, ensuring that crops remain viable through harvest. Understanding the specific damage caused by different pests helps in making informed pest management decisions.
