Madagascar Hissing Cockroaches (Gromphadorhina portentosa) have evolved biological structures specifically designed for territorial combat. This experiment attempts to discover under what types of stimuli will cockroaches exhibit this behaviour, and whether the age and sex of the individual cockroaches affect this behaviour. The habitat and population were changed to determine the appropriate stimuli, and the age and sex of cockroaches engaging in behaviour were recorded. This experiment attempts to learn more about the Madagascar Hissing Cockroach, which are actually little known despite their global status as popular pets. Although this purpose doesn't really benefit the greater good of humanity, the fact that cockroaches in general are not all pests need to be clarified. After viewing this project at the Vancouver District Science Fair, many people's attitudes changed about these amazing and harmless insects. Therefore, this project also aims to educate people about the true nature of this species. Their territorial behaviour, including their defining characteristic, hissing, is their most interesting aspect, so people who know more about it will be more likely to connect with these cockroaches. This project is both about discovery and education, and it aims to do as much as possible for these interesting and misunderstood animals.
