One of the animals that can bother bees is the toad (Buffo) which you have
in great abundance there.  A toad will sit in front of a hive and devour
bee after bee.  Protection usually involves putting the hive up higher.
 
In North America, bears can be a real threat, and beekeepers use electric
fences to fend them off.  In Africa there must be a number of animals which
eat bees... one would be the honey badger, which will crawl right into a
hive and eat the whole thing.
 
Rats and cockroaches will raid hives, and making the hive entrance just big
enough makes the bees more able to defend it.
 
Bee diseases can be prevented by an aggressive breeding program,
concientious cleanliness, by good inspection, national quarantine on
imports and enforced destruction of diseased hives.

Pesticides threaten bees, and to protect them a comprehensive program of
coordination between beekeepers and farmers is needed.  This is
particularly so where mixes of different crops occur in the same area...
grapes and apples etc. and the farmers of one crop might want to spray
while bees are in the area for another.
