A fitness cost resulting from Hamiltonella defensa infection is associated with altered probing and feeding behaviour in Rhopalosiphum padi

This study shows that Hamiltonella defensa infection alters aphid feeding behavior, leading to reduced performance on poor quality plants.

Partial-resistance against aphids in wild barley reduces the oviposition success of the generalist parasitoid, Aphidius colemani

This study shows that partial resistance in wild barley reduces parasitoid success by directly affecting the plant environment, not by reducing aphid suitability.
