Eva Diehl, Elvira Sereda, Volkmar Wolters and Klaus Birkhofer Effects of predator specialization, host plant and climate on biological control of aphids by natural enemies: a meta-analysis Journal of Applied Ecology 50

Specialist predators alone or assemblages of specialists and generalists had the strongest effect on aphid populations, especially when either feeding on grasses and herbs or when exposed to extreme weather events. The control of aphids by natural enemies is most promising in grass and herb crops, whereas it is less suited for controlling aphids in legume crops. Facing climate change, the effect of extreme weather events on aphid control by natural enemies will have further implications for developing management strategies for aphid control in the future.
