São abordados: Posição sistemática, Habitat, Distribuição geográfica, Morfologia externa, Morfologia interna dos sistemas digestivo, excretor e reprodutor, Reprodução e desenvolvimento pós-embrionário e Aspectos comportamentais. / A detailed morphological and biological study of the cookroach Hiereoblatta cassidea (Eschscholtz, 1822) (Dictyoptera, Blattodea, Blaberidae), some taxonomic data, some notes ot its behavior, as well as, their inborn responses to the challenge with the environment, are given.

Mating behaviour of cockroaches is spectacular phenomenon with three different mating patterns traditionally distinguished. The most common and probably ancestral is type A - female climbing. Then it is type B - male climbing and type C - no climbing. Mating type was described in around 30 Blaberidae species. As it is the only cockroach family where all three types are present, it is an interesting model group for studying evolutionary questions. The main goal of the thesis was detail exploration and description of mating sequences in 21 Blaberidae species, 17 of which haven't been examined in this aspect before. An intrageneric diversity in mating patterns (genus Pycnoscelus) was described for the first time. Moreover, in case of P. tenebrigera, it was not possible to assign its mating pattern to any of the three traditional types. Multidimensional statistical analysis and biological interpretation of qualitative behavioural elements revealed two well separated clusters of mating sequensces. Consequently, we propose to distinguish only two types of mating pattern - ancestral type (identical with type A) and derived type. We also discussed the relationship between wing reduction and occurence of derived mating types. Evaluation of quantitative behavioural elements revealed positive correlation between...
