Lineages of the common bedbug Cimex lectularius associated with bats and humans separated from each other tens or hundreds of thousands years ago. Currently, they are genetically isolated and some degree of postcopulatory reproduction barrier has been shown. This thesis aims to test the possible mechanisms of precopulatory isolation. Possible differences of semiochemicals between the host lineages were examined by experiments in arenas (four shelters, two unconditioned, one conditioned by scent of specific lineage and one by scent of non-specific lineage, put together in one arena, to which one bedbug male was introduced every time). For the experiment, six breeds (three from bat lineage and three from human lineage) which originated from different parts of Czech Republic were used. |
