Zhodnocení výskytu škůdců jabloně v okolí Nosislavi
Fröhlich, Pavel
Significant pests of apple trees were observed in orchard near Nosislav in 2016. Pheromone traps were used for the observation of Cydia pomonella and white sticky traps were used for the monitoring of Hoplocampa testudinea. The others pests were monitored by the visual inspection. The abundance of Cydia pomonella was higher this year than in 2015 and it was high to mass degree. First adults were discovered 5th May and the last 16th September. The abundance was find out with two maximum at 16th - 30th May and 11th - 19th July. The abundance of Eriosoma lanigerum and Diaspidiotus perniciosus was high to mass degree. The occurrence of Aphis pomi and Dysaphis plantaginea was medium degree and for Hoplocampa testudinea it was low degree.

Škůdci jabloně v okrajové části Drahanské vrchoviny
Popelková, Eliška
Bachelor thesis is aimed at pests occurring in apple-trees in marginal part of Drahanská vrchovina. Apple-tree pests research was conducted by pheromone traps in village named Dzbel at Drahanská vrchovina in season 2018. In thesis I dealt with four species, Cydia pomonella (Linnaeus 1758), Pandemis heparana (Denis & Schiffermüller, 1775), Lymantria dispar (Linnaeus, 1758) and Euproctis chrysorrhoea (Linnaeus, 1758). From monitored species the most abundant was Cydia pomonella in number of 86 individuals which were captured in pheromone trap for him and 117 individuals which were captured in pheromone trap for Euproctis chrysorrhoea. Males by Lymantria dispar were captured during the season in number of 11 and male by Euproctis chrysorrhoea was captured just one. Pandemis heparana did not appear in the garden. Not only targeted species were captured, but also nontargeted species, seven of which were Noctua fimbriata (Linnaeus 1758) and were captured in trap for Euproctis chrysorrhoea. Also, three species were found, from each only one. In trap for Euproctis chrysorrhoea were caught Oligia strigilis (Linnaeus 1758), for Lymantria dispar were Lymantria monacha (Linnaeus 1758) and for Cydia pomonella was caught Pasiphila rectangulata (Linnaeus 1758).

Škodlivost obalečů na slivoních a jabloních na ošetřovaných a neošetřovaných dřevinách
Pražanová, Žaneta
The occurrence of Cydia pomonella and Grapholita funebrana was observed in 2015, in the village Újezd u Černé Hory near Blansko. Monitoring was performed at two study areas. Pheromone traps were used for monitoring. Cydia pomonella and Grapholita funebrana were detected on the both study areas. C. pomonella was occurred from 10th May to 6th September and G. funebrana was occurred from 4th May to 6th September. Totally 113 individuals of C. pomonella and 221 individuals of G. funebrana were caught on the treated trees. Totally 141 individuals of C. pomonella and 251 individuals of G. funebrana were caught on the untreated trees. In the one pheromone traps were caught 15 individuals C. pomonella, 13th June and 21 individuals G. funebrana, 1st August.

Methodology for evaluation of pest resistance to zoocides by biological methods and antiresistance staregies
Kocourek, František ; Stará, Jitka ; Zichová, Tereza ; Hubert, Jan ; Nesvorná, Marta
The methodology contains description of biological methods for evaluation of pest resistance to zoocides arranged according to world standards. The methods are verified on case studies on pests with proved resistance to insecticides or with high risk of selection of resistance in Czechia, as pollen beetle, Colorado potato beetle, cabbage seedpod weevil, cabbage stem flea beetle and codling moth. The methodology contains survey of basic principles of insect resistance management and proposals of antiresistant strategies for pest mentioned in the case studies. The methods for evaluation of resistance are utilized for resistance monitoring performed by state administration or other organisations. Recommendations given in antiresistant strategies are utilized for pest management in winter rape, potatoes and apples.

Neo-sex chromosomes and adaptive potential in tortricid pests
SÝKOROVÁ, Miroslava
Although most of moths and butterflies possess high number of small undifferentiated chromosomes, in the family Tortricidae extraordinary large Z chromosome has been observed. In this study, the physical mapping of this sex chromosome in the major pome fruit pest Cydia pomonella (Tortricidae) revealed a fusion between an ancestral Z chromosome and chromosome 15 in Bombyx mori reference genome. Furthermore, the sex linkage analysis by qPCR has shown that the rearrangement originated in common ancestor of tortricid subfamilies Olethreutinae and Tortricinae. As the Bombyx mori chromosome 15 contains several genes involved in detoxification pathways and insecticide resistance, this fusion could have facilitated adaptive evolution and radiation of tortricid pests.

Use of \kur{Notch} gene for the production of genetic "sexing" lines of codling moth.
ŠVELLEROVÁ, Hana
The codling moth, Cydia pomonella, is the key pest of pome fruit and walnut orchards in the temperate regions of the world. The extensive use of insecticides for a control of this pest has resulted in the development of resistance to these chemicals, and there is an increasing demand on the use of environment-friendly control tactics, such as the Sterile Insect Technique (SIT). Codling moth SIT relies on the mass rearing and release of genetically sterile both males and females into a wild population. However, male-only releases could significantly reduce costs of the mass rearing and increase SIT efficiency. In this thesis I focused on the use of a temperature-sensitive mutant allele of the Notch gene for production of genetic "sexing" lines of codling moth.
