Pyrrhocoris apterus (Heteroptera); Drosophila melanogaster


Research Focus:

In our group we are mainly interested in understanding insect seasonality – diapause; architecture of photoperiodic timer (at molecular, genetic and cellular levels), geographic variability of the photoperiodic timer, Juvenile hormone signaling in reproduction of insects.
The classical genetic models, such as D. melanogaster, display only poor photoperiodic response. Therefore we are trying to "bring" genetic tools to insect species with robust seasonal response. Our favorite organism is the linden bug (fire bug), Pyrrhocoris apterus. In this species we are mainly in terested in: endocrinology (neuropeptides, evolution of neuropeptide receptors), reproductive behavior, circadian clock, phylogeography of P. apterus and its adaptation.
