How many generations per year can a granary weevil produce?

• A. 1 or 2
• B. 2 or 3
• C. 3 or 4
• D. 5 or 6

Answer: (C)

Granary weevils, which are pests typically found in stored grain products, have a prolific reproductive cycle that can lead to substantial infestations. The correct answer indicates that granary weevils can produce 3 to 4 generations per year under favorable conditions. This reproductive capacity is influenced by environmental factors such as temperature and humidity. In optimal conditions, females can lay numerous eggs in grain kernels, leading to multiple generations in a single year. The lifecycle stages of the granary weevil—from egg to larva, pupa, and adult—take place relatively quickly, allowing for this high rate of reproduction. Understanding the generational potential of granary weevils is crucial for effective pest management strategies in storage facilities, as even a few individuals can rapidly escalate to a larger problem if not managed appropriately. This highlights the importance of monitoring stored grains for early signs of infestation to prevent extensive damage.
