In which season does the alfalfa weevil primarily feed on alfalfa leaves and stems?

The alfalfa weevil primarily feeds on alfalfa leaves and stems during the spring season. This timing aligns with the life cycle of the weevil, as adults emerge and become active in the spring when temperatures begin to warm and alfalfa plants are actively growing. The larvae of the alfalfa weevil feed on the tender foliage at this time, causing significant damage to the plants. This is particularly crucial because the feeding activity during spring can impact the overall yield and quality of the alfalfa crop, which is a valuable forage resource. Understanding this seasonal feeding behavior allows farmers and pest managers to implement targeted control measures at the right time to mitigate damage to their crops.
