Which common stored product pest is known to attack whole grains and chew through the seed coat?

The rice weevil is known for its ability to infest and damage stored whole grains by burrowing into the seed coats. This pest specifically targets a variety of grains such as rice, wheat, and corn, and can cause significant damage by feeding on the inside of the grain, leading to reduced quality and quantity of the stored product. Unlike some other pests listed, the rice weevil has specialized mouthparts that enable it to chew through the hard seed coat, allowing it to access the nutritious endosperm inside. This behavior makes it particularly effective in causing damage to stored grains, which is a significant concern in agriculture and food storage.

Other pests may have different feeding behaviors or target different types of materials, making the rice weevil distinct in its attack on whole grains.
