What is the damaging stage for the Drug store beetle when it infests stored grain?

• A. Eggs
• B. Larvae
• C. Pupae
• D. Adult/Larvae

Answer: (D)

The damaging stage for the Drug store beetle when it infests stored grain is primarily the larvae, although adults can also cause some damage. The larvae are particularly problematic because they are the stage that actively feeds on the stored grain, consuming a variety of foodstuffs, which can lead to significant contamination and loss of quality in the grain. The adults may have a minor impact as they also feed but are primarily focused on reproduction rather than significant feeding activity. In the context of the Drug store beetle lifecycle, eggs hatch into larvae, which are the primary destructive force due to their feeding habits. Once the larvae mature, they enter the pupal stage, during which they do not feed, but rather transform into adults. This emphasizes that the larval stage is the most directly involved in causing damage to stored products. Therefore, while adults are capable of causing some level of damage, in the context of a stored grain infestation, the larvae are the main concern, making the combination of both adult and larvae a relevant choice, but the larvae are the primary agents of damage.
