Device for measurement and regulation of edible insect breeding conditions
Dvorský, Adam ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This work focuses on the design and realization of a measuring and regulatory system for successful breeding of edible insects with a focus on the mealworm (Tenebrio molitor). For the correct setting of the system, the first part of the work is detected and described the general conditions of insect breeding. The description is mainly focused on the mealworm, its development and basic breeding conditions (temperature, humidity, etc.). This information is further used for the development of breeding equipment, the basic concept of which is further established at work. The device is controlled by espressif's ESP32 microcontroller. The work acquaints with its programming and the connection and programming of basic components for the proposed system. Experimental measurements verify the functionality of measurements and regulation in the breeding box. The regulation is accurate to tenths to hundredths of ° C.Last but not least, the design is compared with existing devices.

Hmyz - (staro)nová potravina: ekonomické souvislosti a marketingová strategie
Poul, Marek
POUL, Marek. Insect – (old)new foodstuff: economic context and marketing strat-egy. Bachelor thesis. Brno: Mendelova univerzita v Brně, 2020. This bachelor thesis deals with entomophagy, therefore usage of insect as a source of nutrition. Thesis comprises of topic-related literary research together with ran-domly selected Czech and foreign companies, which are analysed using the 4P method. Thesis also includes a comparison of foodstuffs containing insect compo-nent with their counterpart, in which insect component is not present. The main objective is to propose a marketing strategy for Czech company WormUP, which is engaged in insect foodstuff production. For these purposes, SWOT analysis was used to subsequently create four marketing strategies.

Vliv krmiv na výnos jatečního materiálu hmyzu (Tenebrio molitor)
MUCHKA, Lukáš
Bachelor thesis consists of theoretical and practical part. The theoretical part of this work deals with the consumption of edible insects both in the world and in the Czech Republic. Furthermore, the advantages and disadvantages of the consumption of edible insects and their nutritional value are described. It also includes characteristics of the mealworm (Tenebrio molitor). An important part of the thesis is the practical part, whose aim was to determine the effect of different types of protein feed in the breeding of mealworms. Here their effects on the weight yield of insect slaughter material were compared. The experiment was carried out using four types of protein feed: plant protein (soy), animal protein (dehydrated eggs), complex feed (feed for aquarium fish) and mix of the above feed. Breeding took place in the months of October - December 2019. Two experimental generations of adult insects were bred for egg production. The subsequent egg separation produced separate generations of insects which were fed for fifty-two days. The experiment found that the best results in the breeding of mealworms are achieved by insects, which are fed with a mix of feed in which the largest amount was harvested. Successful breeding of edible insects, however, requires the interplay of several conditions. The choice of feed is one of the important criteria to be addressed. This work is a basic study which can be followed by more detailed experiments.

Optimization of breeding of darkling beetles due to possible use in human nutrition
MAJEROVÁ, Tereza
This thesis was created to find a suitable substrate for feeding the larvae of the darkling beetle (Zophobas morio) intended for human consumption, as well as to find out if the larvae contain, among other substances, gluten. This species is very suitable for entomophagy for its breeding simplicity and nutritional composition especially rich in fats and proteins, similar to its relative, mealworm beetle (Tenebrio molitor). The topic of entomophagy is currently up-to-date due to the growth rate of the human population, whose needs are increasingly burdensome for the environment. At the same time, insect production is cheaper and more efficient than the production of the conventional meat (beef, pork, poultry) and also consumes less water. For the purpose of the experiment, 540 larvae were kept under the same conditions, divided into groups of 15 individuals with a total initial weight of 1g. 9 repetitions were made for each of the four selected substrates. The experiment lasted 3.5 months and during this time 8 measurements (weighing) were performed. The larvae feeding on substrates containing gluten were growing faster in the first half of the development, but there was no statistical difference between the final weight of the larvae on the different substrates, the average weight of one larva was between 0,7248 g and 0,8048 g. Laboratory analysis failed to detect the presence of gluten, the protein content ranged from 25 to 34%, the fat content was between 49 - 61%, these values are eventually compared with the results of other authors.

Insects as human food
Augustinová, Šárka ; Frouz, Jan (advisor) ; Pivnička, Karel (referee)
Insects as a traditional source of food widespread in tropical and subtropical regions offer significant nutritional, economical and ecological gains not only to rural communities. Western bias against insects led to gradual reduction of usage of insects as food without any compensation for lost sources of nutrition and other benefits. Current efforts of the Western world to prevent starvation of population and undo the consequences of inconsiderate human interventions into the environment are often futile and ineffective. One of possible answers to these global problems could be reestablishment of insects as a food source for the native population. Insects offer a renewable source of protein with nutritional values as high as 3186kJ per 100g of solids which exceeds the values of most species traditionally cultivated. The protein content varies throughout the various insect species from 30% in wood-worms to 81% in wasps of the genus Polybia. Moreover, the quality of these proteins is very high and the high values of the amino acids contained outperform the FAO recommended designs. Many species contain important minerals such as calcium, sulfur, iron, phosphor, magnesium and zinc and are as well rich in B vitamins, niacin, riboflavin and thiamin, which are often not incorporated enough into standard meal...

Návrh marketingové strategie - hmyzí protein jako běžná součást lidského jídelníčku
Kopúnová, Kateřina
This bachelor thesis deals with the creation of a marketing strategy for products containing insects, some of which are included in the list of novel foods thanks to new legislation in the European Union. The aim is to design marketing strate-gies based on SWOT analysis, which would help to increase sales of insect prod-ucts in the Czech Republic. This SWOT analysis is based on a literature research dealing with entomophagy, namely its history, current practice, environmental and nutritional aspects compared to the meat and legislation in the European Un-ion. Another source was an analysis of companies in the USA and the EU, which are already engaged in the sale of these products, and also the results of a question-naire survey, which was attended by 445 respondents. The result was the creation of 4 marketing strategies, and on one of them were also calculated the costs.

Využití trubčích larev jako potenciálního zdroje výživy pro člověka
Kolatková, Zuzana
The thesis is focuses on possibilities of harvesting drone brood, it‘s conservation and processing – especially in home conditions. It deals with some nutritive aspects of samples of dry basis of the drone brood which was gained by various methods of dry-ing. Primarily by it‘s fat content, of some mineral substances, micronutrients and heavy metals. Regarding the mentioned samples, furthermore there are monitored the diffe-rences in the microbial profile of the observed samples and differences, which happen after some time of the storing. With respect to the samples of dry basis and the final product in the form of a nutrition ball, there was performed a sensory evaluation and a questionnaire survey.
