The pests affecting strawberry crops will vary between protected and open field growing, and from northern to southern climate zones. Control techniques will also vary depending on crop conditions.
Strawberries attract very many species of aphids, and populations can develop too rapidly for parasitoids to perform well. Predators that will feed on a wide range of aphid species therefore offer better control.
Note that some beneficial mites or insects may require licences or permits for use in some countries and, therefore, some of the species listed below may not be available.
