The Strawberry blossom weevil, Anthonomus rubi is a weevil that feeds on members of the Rosaceae and is an important pest of strawberry (Fragaria x ananassa Duchesne) and raspberry (Rubus idaeus L.). This insect is a particularly problematic pest of strawberry in Europe, in some cases responsible for up to 80% loss of the berry crop.[1] Adults feed on strawberry foliage, and females lay eggs inside unopened flower buds (one egg per bud) before partially or totally severing the stalk;[2] larvae develop inside the severed buds, feeding on the wilting tissue.

Role of pheromones[edit]

Adults are thought to be attracted to strawberries by chemicals released by the plants. Monoterpenes, sesquiterpenes, and aromatic compounds acted as odorants (attractors) on weevils' receptor neurons.[3] Male A. rubi then release their own blend of aggregation pheromone, three components of which have been shown to attract weevils to baited traps.[4]
