In old days every farmer in our village had a beehive - the honey and pollination services were both much appreciated. My father has always taught me that killing a bee is a horrible crime.

Can you support those claims?
Oh... Another reference: http://www.pnas.org/content/99/26/16812.full - you can check references [6,7] yourself.
Edit: I apologize - since I did limit my rant to honeybees initially.
The 2nd reference is the best so far, it provides some quantitative information about how dominant the honey bee is as a pollinator of commercial crops.
Personally I think bees are hugely important and it's quite sad the way bee populations have been mistreated, but it doesn't help to overstate the case (the case for being kind to bees is already very strong).
My ancestors managed to create arguably the best bee btw :) [http://www.wordiq.com/definition/Apis_mellifera_carnica]
For instance I had pancakes for breakfast this morning. The eggs were from non-native chickens, the milk from non-native cows, the flour from non-native wheat, the canola oil I cooked it in from non-native rapeseed, and the butter I put on it from non-native cows. However all is not lost, I used maple syrup from native maple trees, and put blackberries in it that might have been native. (The baking powder and salt are chemicals that to the best of my knowledge do not come from animals or plants, native or otherwise.)
Edit: When I looked up blackberries I found out that there are several hundred species, and some of the popular ones for cultivation are not native. So I don't know whether that was a native berry.
Which is to say: they're so important that local populations of pollinators are inadequate to requirements, so they have to be supplemented by these mobile colonies.
Bees are actively used for guided pollination, which is not possible with most other insects (not withstanding some experiments with bumblebees in greenhouses). Interesting fact is that you will often find the phrase "crop xxx requires yyy hives" while describing the role of bees in pollination.
