All aphid species studied so far share the same sex pheromone components, nepetalactol and nepetalactone. Variation by different enantiomers and blends of the two components released by different aphid species are limited and can only partially explain species-specific attraction of males to females. While some host-plant odours are known to enhance specific attraction of aphid species, herbivo...

Alternative strategies to the common practice of spraying with insecticide in order to control the rosy apple aphid Dysaphis plantaginea (Pass.) (Homoptera: Aphididae) are required. Biological control by natural enemies is a possible tool. In Asturies, despite the tradition of growing local cider apple trees, there are no studies about the community of D. plantaginea predators and their impact ...

Mass releases of two parasitoid species, Aphidius matricariae and Ephedrus cerasicola, may provide an alternative measure to pesticides control the rosy apple aphid Dysaphis plantaginea in organic orchards. As exploratory study, we tested if presence flower strips between tree rows could improve action three early releases––and other naturally present enemies––on colonies number aphids per tree...
