The Biosystematics Laboratory
In consideration of threats to biodiversity on the earth, especially related to tropical deforestation and global warming, the Biosystematics Laboratory is engaged in various fields of fundamental biology, in order to elucidate and conserve biodiversity on the levels of individual, species, and community. Since insects comprise more than 70 per cent of the known species of all kinds of animals, our research focuses primarily on their morphology, taxonomy, phylogenetics, and biogeography. We are also expanding our research interests to behavioral ecology, molecular phylogenetics and conservation biology including risk assessment and control of alien species.

The main research subjects are:
Phylogenetic systematics, biogeography, molecular phylogenetics and environmental monitoring of butterflies;
Biosystematics and ecology of Cynipoidea (Hymenoptera);
Biology and phylogeny of beetles, especially of the superfamily Scarabaeoidea;
Phylogenetic systematics and ecology of Tachinidae and other higher flies

The current main research projects are:
Inventories of tropical Asian insects (TAIIV) ;
Ecology and risk assessment/control of alien insects;
Phylogeny and biogeography of wood-feeding insects distributed in the areas of Gondowana origin based on mitochondrial DNA sequences;
Red Data Book of insects

The current research subjects of graduate students are:
Evolutionary biology of Papilionidae (Chilasa group);
Studies on the saproxylic insect communities in Sabah, Malaysia;
Phylogenetic systematics and biogeography of Pieridae (Cepora, Eurema)
Phylogenetic systematics and biogeography of Nymphalidae (Limenitidini, Charaxes, Tirumala);
Phylogenetic systematics and biogeography of Tachinidae (Phasiinae);
Phylogenetic systematics of Drosophilidae (Phorticella s. str.)
