Which pest is known for having a C-shaped grub?

The correct answer is Drugstore beetle because this pest is characterized by its C-shaped grubs, which are typically found in stored products. The larvae develop in food sources, such as cereals, spices, and dried fruits, making them significant pests in the realm of stored product protection. The C-shape of the grub is a distinctive feature that aids in identifying them during pest control inspections.

In contrast, the rice weevil is primarily known for its adult form and does not have a C-shaped larval stage. Both the cigarette beetle and the Angoumois grain moth also lack the typical grub shape when they are in their larval stages. Proper identification of pests, including recognition of their larval forms, is crucial for effective pest management strategies. This understanding highlights the importance of being able to identify the life stages of different pests to implement appropriate control measures.
