Milk thistle is grown in the Czech Republic as a medicinal herb; silymarin is isolated from its achenes and used for the production of liver and gallbladder medicine. The quality and content of the active compound is influenced not only by environmental factors, but also by pests and pathogens. The occurrence of pests of milk thistle variety Silyb was observed in two localities during the years 2011 2013. In the year 2011 the mycoflora of seeds of four milk thistle varieties was determined. Representatives of 15 species were isolated from the seeds, most of them saprophytic. 21 fungal species were isolated and identified from milk thistle plants during the vegetation; Septoria silybi among the most important ones. Possibilities of protection of milt thistle against pathogens are discussed.

Results of an analysis of dipteran pests composition and changes of their importance in agricultural, horticultural and ornamental plants during the 20th century are given. Even 89 Diptera species have been registered as pests of these plants (1.1 % of all species known in the Czech Republic). Of these ca 14 (16%) species caused regular and important and other 23 (26%) species occasional damages. The remaining 52 (58%) species are unimportant, local and sporadic pests. Only small changes (10% maximally) in the species composition of more important dipteran pests have been registered during the century.

Abstract This epidemiological study monitored the occurrence of the coccidia genus Eimeria and their species composition over a oneyear period at an organic sheep farm in the Czech Republic. Individual faecal samples were collected from thirty lambs and thirty ewes once a month throughout the whole survey. As a result, 348 and 333 samples from ewes and lambs respectively were evaluated using the faecal flotation technique. The overall prevalence of eimeriosis was 75.7% and 54.0% for lambs and ewes respectively. Four Eimeria species (E. ovinoidalis, E. crandallis/weybridgensis, E. parva, and E. intricata) were identified in both, lambs and ewes, during this survey. The most prevalent species was E. ovinoidalis, with an overall prevalence of 84% in ewes and 85% in lambs, followed by E. parva and E. crandallis/weybridgensis. The oocysts faecal output was seasonal. The highest oocysts per gram levels were detected in February (139 000) and May (250 000) in ewes and in February (1 949 900), March (326 000), and May (187 700) in lambs. The intensity of Eimeria infection differed significantly (P < 0.0001) between ewes and lambs during the monitored period.

AbstractThe distribution and ecology of desmids in wetland habitats in the Czech Republic were studied during 2003–2007. Samples were taken also from various aerophytic habitats and temporary pools thet had not been sufficiently studied before. Altogether 110 desmids taxa were found in 31 samples which were ordinated on the basis of their desmid species composition using a multivariate statistic method. The discussion focuses on the most interesting findings and on the factors that influence the distribution of desmids in different types of aerophytic habitats.

AbstractThis paper aims to analyze the regional cooperation which ensures stability and good relations to neighbours and other V4 countries and helps to enforce collaborations across Europe in many fields such as education, tourism and economic development. Another field of activity of the Visegrad Group is a joint positioning in international tourism which will be addressed in this article on the background of the current coronavirus crisis. The empirical part consists of a SWOT analysis for Visegrad group challenges and a PASTA Analysis with which the effects of the coronavirus pandemic on the tourism industry in the V4 countries are researched. Lastly, recommendations for possible further actions in times of the coronavirus will be given, and potential future collaborations with the WB6 and EaP countries, also with regard to tourism, will be dealt with briefly. This article summarizes aspects related to tourism market, transport, cultural offer, economy, industry, and environment. The particular focus is also paid to political, economic, sociological, technological, legal and environmental factors of the Czech Republic, Poland, Hungary and Slovakia and how the current coronavirus and the resulting measures against the spread of it affects the tourism industry in the Visegrad Group countries.

Application Rates

Cattle slurry is frequently used fertilizer on grasslands, but little is known about its effect on plant species composition. The aim of this study was therefore to assess effect of different application rates of cattle slurry (S0 &ndash; 0, S1 &ndash; 60, S2 &ndash; 120, S3 &ndash; 180, S4 &ndash; 240 kg N/ha/year) on the plant species composition of three-cut grassland. The study was performed over 6 years on moderately moist upland Arrhenatherion grassland in the Czech Republic dominated by Alopecurus pratensis, Trisetum flavescens, and Poa spp. Species composition recorded in treatments with application of cattle slurry in rate up to 120 kg N/ha/year was similar to the unfertilized control. During first three years, species richness was similar in all treatments and then decreased the most in S4 followed by S3 treatment. Cover of short forbs increased in S0 and decreased with an increase in slurry application rate which supported tall grasses. Application of cattle slurry up to 120 kg N/ha/year can be considered as suitable compromise between maintenance of species rich grasslands and requirements of farmers for sufficient forage production.

First Time

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.
