Chemo-ecologically mediated interactions among Candidatus Phytoplasma mah, its vector Cacopsylla picta, and their host plant Malus domestica

by: Christoph J. Mayer, Andrea Vilcinskas, and Jurgen Gross

In: BULLETIN OF INSECTOLOGY, Vol. 60, Nr. 2 (2007) , p. 209-210.

Abstract

Apple proliferation caused by the apple proliferation phytoplasma, �Candidatus Phytoplasma mali�, causes major economic losses in European apple production. The apple proliferation phytoplasma is naturally spread by the two leaf sucker species Cacopsylla melanoneura and C picta Hemiptera: Sternorrhyncha: Psyllidae It was investigated in a previous study that both psyllid species use chemical cues for orientation. In this study investigation were: carried out on the behavioural reactions of C. picta on volatiles from healthy plants and those infected with apple proliferation in respect to the infection status of the psyllids themselves and to their previous host experience. The influence of the apple proliferation phytoplasma on the volatile emission of apple trees was investigated by head space collection followed by gas chromatography coupled with mass spectrometry. The differences in the behavioural responses to the volatiles of infected versus non-infected plants as well as the respective differences detected among the volatile compounds will be presented and ecological interactions between the association of C picta and �Ca. P. mali� will be discussed.
