Climate change and global warming are directly effecting the population dynamics of insects of medical importance and insect pests of agricultural commodities during the last few years. The outbreak of some insect-borndiseases and decreasing yield of agricultural products are both caused and results of climate change are known everywhere in the world. Recent reports of honey bee diseases and out breaks, as well as increase in the incidence of CCD(Collapse Colonial Disease) are causing great concerns and pose big problem for our bee keepers in many countries in North America and Europe. These important infectious diseases are possible carried and propagated by bee mites primarily by Varroa mites, which have recently experienced increasing populations in USA and UK includes some European countries. Recently some Asian honey bees adapted to live in the urban areas as the example of Apis dorsata move to Mae Fah Luang Campus more than 30 colonies and even in Chulalonkorn Campus more than 10 colonies increase from few colonies in the the last few years. Apis florea have been found more than 161 colonies this year in Kanchanaburi (River Kwai province) this year(2009). The discussion of some wild honey bees migration will concentrate on research program of our bee research unit of the university in Thailand.
