Bionomie mer přenášejících phytoplasmy,působící proliferaci jabloně
Němcová, Pavlína
This article tries to generally summarize questions about Apple Proliferation Phytoplasma and how the phytoplasma is transfered. Especially the morphology and bionomy of insect vectors are described. The Apple Proliferation is significant disease caused by Candidatus Phytoplasma mali. Usually the apple trees are affected by the disease. The sensitivity and reaction of each variety and rootstock are different. The symptoms of disease can be very variable and the disease changes to its latent phase very often. The symptoms can almost disappear and than come back again (The Recovery Syndrome). Members of Cacopsylla genus are signified to be the main Phytoplasma vectors. The article is aimed to C. picta and C. melanoneura where the transmission of AP has been proved and C. mali where the transmission of AP is supposed. The second part of the article describes my own research of presence of AP vectors in Ratíškovice willage in 2005. The presence of AP vectors was not proved in this location.
