A role of adipokinetic hormones in insect lipid metabolism
BÁRTŮ, Iva
This PhD. thesis summarizes the effect of adipokinetic hormones (AKHs) on a spectrum of mobilized lipids in model insect species the locust Locusta migratoria and the firebug Pyrrhocoris apterus. The results revealed that mobilization of diacylglycerols and fatty acids from the fat body into the haemolymph is not uniform and suggested there is partial specificity of individual AKHs. This could contribute to the answer of the question why some insect species have more than one AKH. The results of the thesis are supplemented by studies of AKH effect on lipid metabolism in stress conditions elicited by insecticide treatments. Co-application of AKH and insecticide enhanced the effect of insecticide

Physiological mechanisms of aging in maless of model insect species
PROVAZNÍK, Jan
Trade-off between reproduction and longevity is a widely accepted fact, yet proximate mechanisms are scarcely understood. In this work I tested differences in lifespan between diapause and non-diapause males of a model insect, the linden bug Pyrrhocoris apterus. Also the role of juvenile hormone in regulation of longevity and immunity (measured by relative phenoloxidase activity) was assessed. In addition to that, I examined if juvenile hormone is the mediator of reduction in longevity induced by mating.

Insects. Series of creative lessons for art education on the primary school.
KANKRLÍKOVÁ, Eliška
This diploma thesis presents theoretical and practical materials for primary school art teachers. It deals with the theme of ?Insects? and how it can be taught to pupils from the third to fifth class of primary school. The theoretical part examines the biological, didactic as well as artistic aspects of the topic. The last chapter concentrates on the project method in art education. The theoretical part is followed by a concrete art series consisting of six art activities described in detail. The work is completed with a rich picture appendix, including a CD with motivational PowerPoint presentations.

Ecological education in nursery school
MRÁZKOVÁ, Kristýna
Mrázková, K.: Ecological education in nursery school Insects and spiders as model taxon within ecological education in nursery school An educational proposal for work with pre-school children aimed at closer familiarization with life of insects and spiders has been elaborated. The submitted proposal has been developed into eleven incorporated sections connected through a motivational fairy-tale "Little George among beetles". Six of these sections have been tried out and in terms of field-test results and gained experience the implementation of remaining five is now being arranged. Work and grapho-motive sheets for children of pre-chool age have been also designed and presented with each topic.
