Cacopsylla melanoneura is a univoltine psyllid vector of 'Candidatus Phytoplasma mali', the etiological agent of apple proliferation (AP), a severe disease in European apple orchards. The influence of 'Ca. P. mali' on the fitness of C. melanoneura was studied. In the spring of 2007, male-female pairs of field-collected adults were exposed to 'Ca.

Abstract
Cacopsylla melanoneura is a univoltine psyllid vector of 'Candidatus Phytoplasma mali', the etiological agent of apple proliferation (AP), a severe disease in European apple orchards. The influence of 'Ca. P. mali' on the fitness of C. melanoneura was studied. In the spring of 2007, male-female pairs of field-collected adults were exposed to 'Ca. P. mali'-infected or healthy 'Golden Delicious' apple shoots. Exposure to these diseased shoots did not affect the life span of the adult psyllids. However, significantly fewer eggs were laid on the diseased shoots. Furthermore, fewer of the eggs that were laid on the infected plants hatched. Data suggest a detrimental effect of AP phytoplasma on the fitness of C. melanoneura. © 2009 Elsevier Inc.
