Technical Abstract: The Diaprepes Root Weevil (DRW), Diaprepes abbreviatus (L.), and the Blue Green Root Weevil, Pachnaeus litus (Germar), are both pests of nurseries and citrus groves in Florida. The DRW is the more serious pest, and counts of egg masses are often used as indices of abundance and potential damage. Unfortunately, egg masses deposited by these weevils cannot be visually differentiated and rearing-out is cumbersome. We developed a simple and quick molecular approach to distinguish the egg masses.
