Ladybug biology and invasion ecology

Ladybugs are remarkably popular for its conspicuous appearance and valued as predators of plant pests. Also they are known for their extraordinary sexual activity. One ladybug species, the harlequin, became a major invasive species. In our research, we study a wide range of topics, including ladybugs coloration (heredity of coloration, phenotypic plasticity, antipredatory and protective function coloration), foraging ecology of ladybugs, toxicity of ladybugs for predators, microorganisms and other animals, sexual selection in ladybugs (male mating success dependence on the coloration, size and order of mating, paternity testing using molecular genetic techniques). We are also interested in faunistics and taxonomy of ladybugs and their phylogenetic relationships. We study phylogenetic relationships of ladybug species using molecular genetic techniques. We also deal with the spread of the harlequin (Harmonia axyridis). We study its impact on the diversity of native fauna, its presence in the vineyards and how this affects the quality of wine. Furthermore, we study biology, ecology and spread of other invasive species of insects in the Czech Republic and their food requirements and cold resistance.
