Both pathogens were distributed throughout a broad range of environments including forest and riparian stands and probably became naturalised in the country. The two species differed in their frequency and elevational distribution. P. multivora was less frequent, but commonly occurred in the lowest regions such as Central Bohemia and South Moravia, i.e. areas which generally exhibit a high level of invasion. This species was isolated primarily from Quercus robur and found to be involved in oak decline. Moreover it poses a high risk to other forest trees. P. plurivora was distributed in a broad range of elevations over the entire area. A substrate specificity was detected in P. plurivora - the isolates from forest trees were more aggressive to such trees than the isolates from ericaceous ornamental plants.

Suffruticosa and B. microphylla) in a nursery in South Moravia in August 2010. These symptoms were suggestive of box blight on Buxus spp. Characteristics of the visual symptoms, microscopic features, and identification of the isolates using DNA sequencing are described. The causal agent was isolated and identified as Cylindrocladium buxicola Henricot by means of morphological, cultural, and molecular characters. The effect of five commercial fungicides on C. buxicola in vitro was studied. The most effective fungicides (kresoxim-methyl, azoxystrobin, and mancozeb) inhibited conidia germination and mycelial growth (kresoxim-methyl, myclobutanil, and penconazole) of C. buxicola more than 96%.

The highest concentration of B. bassiana yielded the highest H. cunea mortality in all three host plants. The combination of B. bassiana and plant extracts caused the highest H. cunea mortality in all host plants. The difference could be attributed to the nutritional effects of host plants on total physiological status of larvae. To prove this point, the digestive enzymatic assessments were studied and it was pointed out that a statistical difference of α-amylase, protease, and lipase activities exists among larvae feeding upon different host plants. Thus, a combined application of an entomopathogenic fungus and a botanical insecticide may be beneficial for the control of H. cunea.

M. aeneus, M. viridescens, M. subaeneus, M. atratus, and M. coracinus were recorded throughout the observation period, while M. nigrescens was recorded just in 2009 and 2011, M. carinulatus and M. maurus in 2010 and 2011. M. aeneus was the most frequent species of all compared samples (2009-2011). Of the accompanying species, M. subaeneus and M. viridescens were markedly more frequent in this study. Considering high resistance of M. aeneus to esteric pyrethroids, it could be helpful to distinguish among the individual Meligethes species occurring in field samples intended for laboratory testing.

An example is given in order to understand better the calculation. The medians show that the timing is similar at different latitudes despite local phenological differences. The difference in median flight times between Finland and the Czech Republic was five days on average, but phenological differences are about a month, shown by a comparison of temperatures, the monitoring of buds on spruce, and by the stage of the carrot plants. During the attack by T. apicalis the carrot plants are younger towards north what is unusual in Psyllidae. In extreme north locations as Finland the genetic triggering for flight could not be realised by the strong declining of temperatures. Flight occurs here substantially later as to local photoperiodicity but is the earliest as to phenology, including carrot plants. The very small plants during flight are much more damaged here than the well-developed plants in central Europe.

In barnyardgrass (Echinochloa crus-galli) we investigated how fatal germination was influenced by the depth and time of seed burial. The proportion of germinated seeds decreased with burial depth to 0-20% at ≥ 0.1 m depth which is fatal for seedling establishment. The percentage of fatal germination was greater for the seeds buried during the spring season than during autumn. Germination was influenced by seed pre-treatment, after ripening or stratification. Spring ploughing of non-dormant seeds below 0.1 m depth induces fatal germination, decreasing in this way seed bank of barnyardgrass.
