Final answer:
Weevils, moths, and beetles are common stored product pests that attack whole grains and chew through the seed coat, causing damage to the seeds.
Step-by-step explanation:
The common stored product pests that attack whole grains and chew through the seed coat include weevils, moths, and beetles. These pests infest stored grains such as wheat and rice, causing damage to the seeds. Weevils, moths, and beetles reproduce within the seeds, consuming the seed contents and then emerging as adults. This makes them a significant threat to agricultural crops.
