I have added four dataframes on singe canvas. Within Arc environment everything works perfectly but when I export the map to .eps or .pdf or .jpeg two of them are working properly while the other two show a white background which destroys the look of the map. properties of the dataframes are same. kindly give ideas.

This is a known issue: http://support.esri.com/es/knowledgebase/techarticles/detail/17336
Basically it's a problem with using a raster layer in the inset maps. If you can only use vectors on your insets the transparency works.
