Precopulatory behavior in firebug Pyrrhocoris apterus
 Křivánek, Miloš ; Jarošík, Vojtěch (advisor) ; Stejskal, Václav (referee)
The existing research works, dealing with pre-copulatory behaviour in Pyrrhocoris apterus (L.), show that this behaviour follows a simple pattern of mating. The aim of this work is to extend knowledge regarding this type of behaviour. Results were obtained by processing the video footage to monitor the behaviour of individuals of the Central European population (the Czech Republic) as occurred in the respective copulatory zone. Changes were observed in the occurrence and mating activity of each sex depending on climatic conditions and time. Furthermore, the course of individual phases of the mating behaviour, based on mutual interactions and under the influence of external factors, was also observed. These results were supplemented by adding data gained from laboratory experiments, taking place at a temperature of 22 ± 4 řC and involving a long- day type photoperiodic reaction. Based on the results gained, it had been revealed that the climatic conditions significantly influenced the course of behaviour. Individuals of both sexes are physically active during the photo-phase when the intensity of this activity changes in the course of the circadian rhythm. Females display a higher sensitivity to any variation in climate. Males who are influenced by the presence of receptive females show greater locomotive...
