Determination of basic nutritional parameters in edible insects
Korček, Jakub ; Štursa, Václav (referee) ; Diviš, Pavel (advisor)
In this bachelor thesis is dicussed nutritional value of chosen insect species. Analysed samples consisted of worms, crickets and locusts. Analysed parameters were: total nitrogen, crude protein, total lipids and content of chosen elements. Total lipids were, after homogenization, determined by Soxhlet method, using diethyl ether as a solvent. Prior to protein and element determination, samples did undergo Kjehldal digestion process, using sulfuric acid. Weiniger catalyst was only added to samples digested for protein measurement. Element content was determined by optical emission spectrometry with inductively coupled plasma (ICP-OES). Crude protein was determined by Kjeldahl method. The highest protein content was determined in crickets. (75 ± 5) %. Locusts contained the highest lipid content (33 ± 2) %. We also found out, that samples were rich in calcium, potassium, manganese and zinc, which are all important elements for the proper functioning of our body. The results of this thesis prove, that insects can present nutritionally important food.

Beetle armour
Polášková, Lucie ; Ryška, Pavel (referee) ; Vaněk, Vojtěch (advisor)
The bachelor's thesis deals with the creation of an author's accordion book, examining the relationship between textual and pictorial communication of information. The narrative is thematically set in the stylized realm of insects, where it works with the metaphor of the exoskeleton of the beetle as a portable armor, architecture, or outline. The fictional story deals with the life cycle of a beetle. He wonders how beetles are born and how do they leave the world? The aim of my bachelor thesis is the realization of an atypical prototype of an accordion book, which is located on the border of a building kit, a toy and a book. The realization of the prototype will use traditional techniques, including digitization and image post-production.

Cryptids
Dvořáková, Dana ; Turek, Filip (referee) ; Sterec, Pavel (advisor)
Cryptids, video which is studying animals, its shapes, moves and the environment , where they find themselves. The video is looking equal to all entity without any difference, document varied life as same as passing death or rot as well. It also speaks about collaboration and the microworld, which creates perfect unit. Silent mutual conversations.

The Amputee
Sedlák, Ondřej ; Sedlák, Jan (referee) ; Gabriel, Michal (advisor)
Cut out the insect body, which in turn draws attention to detail and a separate form object, it becomes a piece of the unknown, futuristic world, who is a snippet of an enlargement of our macrocosm. Statue focuses on the unusual and the idea of the individual and points to a less pronounced nature.

Control unit for monitoring of climatic conditions in the breeding of edible insects
Chmelař, Vít ; Šandera, Josef (referee) ; Adámek, Martin (advisor)
This bachelor thesis introduces the problematics of edible insects, Arduino platform, sensors and peripherals that will be used to construct a device which monitors conditions of breeding of insects. It describes the different type of sensors and their principles. It discusses the SPI and I2C communication, which is used for communication with peripherals and describes the selected sensors and peripherals with which will be builded the device. Measured values are displayed on devici and savet to memory card.

Scientific literature with the theme of insects in the practice of kindergarten
Faltusová, Kateřina ; Laufková, Veronika (advisor) ; Kadrnožková, Monika (referee)
This master's thesis entitled "Utilization of educational literature on the topic of insects in the practice of preschool education" is divided into theoretical and empirical sections. The aim of the thesis is the development of scientific knowledge through the use of children's educational literature in the preschool environment. The theoretical section outlines the characteristics of preschool-aged children with respect to the topic of the thesis, issues related to environmental education in preschool education, characteristics of literature for children, utilization of educational books in preschools, and an analysis of the Framework Educational Program for Preschool Education in relation to the thesis topic. The objective of the empirical section is to create lessons using educational literature about insects that contribute to the development of scientific skills in children. Additionally, it seeks to determine the popularity of educational books about insects based on the age and gender of the children, as well as to map the reading environment of the children. The results of the practical part were verified based on pretest and posttest, participant observation of children, a questionnaire for parents of pupils, and activities aimed at assessing the popularity of books. The action research...

Retence živin u drůbeže při zkrmování diet s podílem moučky z larev potemníka moučného
Kudlová, Lenka
The aim of this diploma thesis is, if the inclusion of 20 and 50 g/kg mealworm meal (TML) in diets for poultry has an effect on nutrient retention, gastrointestinal morphometry and digesta viscosity. Furthermore, a digesta microbiology of laying hens and biochemical blood parameters of broilers were monitored. The collected samples were subjected to laboratory analysis to determine the nutrient retention, gastrointestinal morphometry, digesta viscosity, digesta microbiology and biochemical analysis of blood. The nitrogen retention was not affected by mealworm meal in broilers (p > 0.05). The nitrogen retention was the highest in the control group in laying hens (p < 0.05). A lower width and height and the highest muscle height of the gizzard, but a longer colon, (p < 0.05) were found in control group of laying hens compared to the experimental groups. No differences (p > 0.05) were found in the villi height of the ileum. The digesta viscosity in broilers was not affected by (p > 0.05) experimental diets. The highest value of digesta viscosity in laying hens was found in the group with inclusion 50 g/kg TML (p < 0.05). No differences (p > 0.05) were found in the microbiology of the digesta between the compared groups of laying hens. Significant differences (p < 0.05) in biochemical blood parameters were found in the concentrations of ALT, total bilirubin, urea, creatinine, glucose and α-1 globulin between control and experimental groups of broilers.

Hodnocení významu druhově pestrých směsí trav, jetelovin a bylin pro biodiverzitu
Fiodorová, Daniela
The aim of the study was to evaluate the species composition and proportion of agrobotanical plant groups in an established species-rich vegetation whitch was set up in 2022 in the first year of growth. Furthermore, the research aimed to determine the feeding value, diversity index, equitability and to assess the honey yield of the vegetation. The study investigated whether the date had an effect on the occurrence of pollinators in the vegetation and which groups of pollinators were most frequent. The vegetation was monitored using phytocenological imaging in a 1 m2 square plot in the centre of the experimental area. Insect abundance was assessed by observation directly in the plot and also by trapping in yellow trays. The recording in the first year of growth of the vegetation mixture showed high infestation. A total of 28 plant species were observed in the experimental plot. The agrobotanical group of herbs was not the most represented by number of species. The date had an effect (p<0,05) on the occurrence of Apis mellifera and the order Diptera. The order Diptera was the most abundant order during observations of infestations and pollinator capture.
