Stressful times in a climate crisis: how will aphids respond to more frequent drought?

D. J. Leybourne, K. F. Preedy, T. A. Valentine, J. I. Bos, A. J. Karley

This study uses a meta-analysis to show drought reduces aphid fitness globally, linked to lower plant vigour and higher plant defenses.

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

D. J. Leybourne, T. A. Valentine, J. I. B. Bos, A. J. Karley

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

D. J. Leybourne, T. A. Valentine, J. I. B. Bos, A. J. Karley

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

Partial-resistance against aphids in wild barley involves phloem and mesophyll-based defences

D. J. Leybourne, T. A. Valentine, J. A. H. Robertson, E. Perez-Fernandez, A. M. Main, A. J. Karley, J. I. B. Bos

This study identifies phloem and mesophyll-based defenses in wild barley that contribute to partial resistance against aphids, involving increased defense gene expression and altered amino acid composition.
