How many generations per year can the Rice weevil produce in stored grain?

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

Answer: (B)

The Rice weevil is known for its ability to reproduce rapidly in suitable environments, particularly when it comes to stored grain. Under optimal conditions, such as warmth and adequate food supply, a Rice weevil can produce 2 to 3 generations per year. This capacity for rapid reproduction allows infestations to escalate quickly if not managed effectively, making it crucial for those involved in pest management and fumigation practices to understand their life cycle. This information highlights the importance of monitoring stored grains, as even a small number of infesting weevils can lead to significant population growth within a single year. Effective pest control measures must take into account the weevil's reproductive potential to prevent extensive damage to stored food resources.
