For stored grain, what is the damaging stage for the Rice weevil?

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

Answer: (D)

The damaging stage for the Rice weevil in stored grain is both the adult and the larvae. Both life stages feed on the grain, causing significant damage. As adults, Rice weevils are capable of boring holes into whole grains to lay their eggs, which leads to larvae developing inside the grains. These larvae also consume the grain as they grow, leading to further deterioration of the stored product. This dual stage of damage is crucial for understanding effective pest management strategies in grain storage. Recognizing that both the adult and larval stages contribute to the damage highlights the need for comprehensive control measures that target both life stages to effectively manage the pest. The other choices focus on individual life stages that contribute to damage but fail to capture this broader perspective of both damaging stages.
