Anthonomus rubi
The Strawberry blossom weevil, Anthonomus rubi is a weevil that feeds of members of the Rosacea 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 one egg per flower bud; larvae develop inside buds.
Role of pheromones
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.[2] Male A. rubi then release their own blend of aggregation pheromone, three components of which have been shown to attract weevils to baited traps.[3]
