Anthonomus pomorum or the apple blossom weevil is a univoltine herbivore of apple trees, Malus domestica.
Life history Adults generally overwinter in leaf litter of forests or hedgerows. In the spring, they emigrate to orchards and colonize apple trees.Toepfer, S., H. Gu, and S. Dorn. 1999. Spring colonisation of orchards by Anthonomus pomorum from adjacent forest borders. Entomol. Exp. Appl. 93: 131-139.Toepfer, S., H. Gu, and S. Dorn. 2002. Phenological analysis of spring colonisation of apple trees by Anthonomus pomorum. Entomol. Exp. Appl. 103: 151-159. They may find their host trees using pheromones or plant-derived chemical cues.Kalinova, B., K. Stransky, J. Harmatha, R. Ctvrtecka, and J. Zdarek. 2000. Can chemical cues from blossom buds influence cultivar preference in the apple blossom weevil (Anthonomus pomorum)? Entomol. Exp. Appl. 95: 47-52.
