| Research Abstract |
Hyphantria cunea has a sibling species in the North America. We investigated the mode of speciation and the effect of global warming on the life cycle adaptation, the two aspects that colonizing species faces and undergoes adaptation after colonization, i.e., competition and adaptation to lacal climatic condition. The results suggest that the two sibling species are distinct species and the reproductive isolation is effected by differentiation in circadian clock and seasonal life cycle. The transition from bivoltine/trivoltine life cycle steadily moves northerly year by year, probably pushed by global warming.
