Since 2002, when the first lecture on entomophagy took place at Mendel University in Brno, till today, participants of these educational lectures were asked to fill questionnaires in order to evaluate interest in entomophagy in Czech Republic and pick suitable species. Analyses of nutritional value of selected species were also performed during this time. The questionnaire was divided into several parts - suitable species, sensory properties, difficulty of breeding and processing and respondents own attitude to the consumption of insect species. For the purpose of this study the questionnaire was evaluated using the semantic differential, so to create a comprehensive picture of each insect species. Based on evaluation of more than 5,000 questionnaires, certain developmental stages of seven species of insect were selected for further evaluation: Tenebrio molitor (TM) larvae, Zophobas morio (ZM) larvae, Gryllus assimillis (GA) nymphs, Locusta migratoria (LM) nymphs, Galleria mellonella (GM) larvae, Bombyx mori (BM) Pupa, Apis mellifera (AM) bee brood, while cockroaches were completely excluded for use in entomophagy. Although they are easy to breed and are available all year-round, consumers showed relatively great disgust. For all of these species, basic nutritional values were analysed, as well as content of amino acids and fattty acids. All parameters were statistically evaluated using ANOVA-1. Each species appears to be suitable for entomophagy for a different reason. Generally speaking, AM, TM and GA were best accepted considering the sensory aspect, nutritional values are interesting especially in BM and GM and TM wins with simplicity of its breeding.
