parthanogenesis

[John Reed]

I am interest in knowing whether parthanogenesis has evolved in the male 
sex of any species.  I would presume not, for evolutionary reasons, but I 
would like to know for sure.  I would also like to know other peoples 
opinions as to why this has not occured.  My last question is simply: in 
what types of organisms does parthanogenesis occur?  I know it occurs in 
insects, what about other arthropods, plants (I believe it does), other 
animals, fungi?  Thanks for any replies.
