During the vegetation seasons 2012–2015, symptoms of severe infections by a rust disease were recorded on plants of the ornamental species Centaurea macrocephala. Based on morphology, the pathogen was identified as Puccinia jaceae or Puccinia hieracii, which have recently been considered as synonyms. However, substantial differences between P. jaceae and P. hieracii in nucleotide sequences of the ITS2 region provide evidence for the molecular identification of the specimen as P. jaceae.

 The presence of Cherry virus A (CVA) in the germplasm collections of sweet cherries and plums was studied. CVA was detected using the specific RT-PCR assay in six of eight sweet cherry and one of four plum cultivars. Specifity of amplicons and distant position of cherry and non-cherry isolates was verified by sequencing and phylogenetic analysis. Results indicate that the cherry landraces and cultivars could be infected by CVA more than it has been assumed.

A survey of viruses on capsicum plants in the Czech Republic was carried out in the years 2006–2010. Altogether, 375 leaf samples with symptoms suggesting viral infection were collected both from open fields and greenhouses. These samples were examined for the presence of Alfalfa mosaic virus (AMV), Broad bean wilt virus-1 (BBWV-1), Cucumber mosaic virus (CMV), Pepper mild mottle virus (PMMoV), Potato virus Y (PVY), Tobacco mosaic virus (TMV) and Tomato spotted wilt virus (TSWV) by ELISA. Viruses detected in the samples were AMV, BBWV-1, CMV and PVY. The most prevalent were CMV and PVY which were present in 24 and 29% of tested samples, respectively. In some cases a complex infection of two viruses was detected. Gene sources of resistance against CMV and PVY are mentioned. The relation of virus occurrence on aphid incidence is discussed.

Ornamental Species

Ornamental aquaculture is one of the main sources of non-native species worldwide. Unintentionally transported “hitchhiking” organisms have been previously recorded; although most of these species are transported from tropical regions, here we report on the first accidental transport of the zebra mussel (Dreissena polymorpha) in a shipment of ornamental Aegagropila linnaei (Chlorophyta) from Russia to the Czech Republic. This invasive mussel is listed on the national blacklist of alien species in the Czech Republic and can be easily released in outdoor garden ponds together with A. linnaei. Since the Czech Republic is known to be a gateway for aquatic ornamental species from a European perspective, re-export to other European countries is also possible. Thus, the spread of D. polymorpha via this pathway cannot be excluded. This finding should be of importance to conservationists, traders, decision-makers and other stakeholders.

Symptoms of viral infection were observed on plants of pepper, cv. OL 228, raised from commercial seeds of Czech origin in a greenhouse in the year 2002. Infected plants showed mosaic or mottling on leaves, and necrotic depressions on fruits. Straight, rod-shaped viral particles of about 300 nm, indicating a tobamovirus infection, were found by electron microscope. ELISA produced negative reactions for <i>Tobacco mosaic virus</i> (TMV) but positive reactions with an antiserum to <i>Pepper mild mottle virus</i> (PMMoV). In biological characterisation using pepper cultivars with the L1, L2, L3 and L4 tobamovirus resistance genes it was found that the Czech isolate of PMMoV belongs to pathotype P1.2. This is the first report of PMMoV in the Czech Republic. Its distribution, however, may still be limited as a survey did not reveal other infections in the main pepper producing areas. As PMMoV spreads with infected seeds, the possibility of its chemical deactivation by NaOH was tested and confirmed.

Damage caused by the Goji berry gall mite, Aceria kuko (Kishida, 1927) was observed on the leaves of Lycium chinense Miller (Solanaceae) in Brno in August 2016 and on L. barbarum L. in Popovice in September 2016. Aceria kuko is a pest of Asian origin which is common in China and occurs only sporadically on Goji berry plants in the European Union. This is the first observation of the Goji berry gall mite occurrence in the Czech Republic.

The species composition, frequency and abundance of insect pests (Coleoptera) occurring outside a grain store were explored. Wheat bait traps were used for pest monitoring; they were changed every month from April to September. For the first time the outdoor occurrence of primary and secondary stored-product pests was documented in the Czech Republic. Seven species of Coleoptera were found outside the grain store. Pest abundance and frequency were in high correlation. The primary pest Sitophilus granarius was dominant.
