Abstract Apricot aphid, Myzus mumecola (Matsumura) (Homoptera: Aphididae), was recorded as a new pest of apricot in Hungary the spring 2020. Identification based on morphological and genetical (mitochondrial COI region) characteristics. M. most likely arrived last 2–3 years has quickly become widespread causing significant damage to young trees. Colony development, differences susceptibility be...
The effect of a recombination event in the genomic 3' end on the biological properties and competitiveness of plum pox virus (PPV) was investigated. Therefore, a fragment spanning the coat protein (CP) coding region and a part of the 3' non-translated region of a non-aphid-transmissible strain of PPV (PPV-NAT) was replaced by the corresponding region of a PPV sour cherry isolate (PPV-SoC). The ...
MOLNÁR ÁGNES MÓNIKA, LADÁNYI MÁRTA, KOVÁCS SZILVIA. 2016. Evaluation of the Production Traits and Fruit Quality of German Plum Cultivars. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 109–114. Due to the substantial damage caused in Hungarian plum orchards by the spread of plum pox virus (PPV), high-yielding, o en self-fertile German, Serbian and Romanian cultiv...
ABSTRACT Thirteen aphid species were tested for their ability to transmit Pennsylvania isolates of Plum pox virus (PPV) collected in Columbia (PENN-3), Franklin (PENN-4), and York (PENN-7) Counties, PA. Four species, Aphis fabae, A. spiraecola, Brachycaudus persicae, and Myzus persicae, consistently transmitted PPV in preliminary transmission tests. Two species, Metopolophium dirhodum and Rhopa...
Originally identified in Bulgaria in 1915, Plum pox virus (PPV) is the most damaging virus of stone fruit trees, including apricot, plum, peach and cherry. PPV steadily spread throughout Europe over the years since its discovery and at the turn of the century (1999-2000) it reached North America (USA and Canada). While many strategies to control the spread of PPV have been undertaken over the d...
Identifying the key factors underlying the spread of a disease is an essential but challenging prerequisite to design management strategies. To tackle this issue, we propose an approach based on sensitivity analyses of a spatiotemporal stochastic model simulating the spread of a plant epidemic. This work is motivated by the spread of sharka, caused by plum pox virus, in a real landscape. We fir...
Sharka, caused by Plum Pox Virus (PPV), is by far the most important infectious disease of peach [P. persica (L.) Batsch] and other Prunus species. The progressive spread of the virus in many important growing areas throughout Europe poses serious issues to the economic sustainability of stone fruit crops, peach in particular. The adoption of internationally agreed-upon rules for diagnostic tes...
This study was conducted in stone fruit orchards five provinces of the East Mediterranean Region Turkey between years 2009-2011. The aim to determine potential aphid vectors quarantine pathogen PPV (plum pox virus, family Potyviridae) that causes serious yield losses. During surveys, 542 orchard/nurseries were sampled and 6 species (Hemiptera: Aphididae) [Brachycaudus persicae (Passerini,1860),...
