Which of the following insect groups readily attacks dry grains?

The insect group that readily attacks dry grains is "boring insects". Boring insects are insects that make holes or tunnels in wood, plant stems, and dry grains. They are named boring insects because they bore into the food or materials to live and reproduce. Some examples of boring insects that attack dry grains include the rice weevil, maize weevil, and lesser grain borer. These insects can cause significant damage to stored grains, making them unfit for human or animal consumption. Therefore, proper storage techniques should be employed to prevent infestation by boring insects.
