Do any fruit trees attract fewer wasps than others?

[PassTheTwiglets]

I want to plant a fruit tree to grow as a fan/espalier along my fence. I was going to go for a plum tree because we love plums, get through lots and I read that they are the easiest to train/require less pruning than other trees. But then I remembered the wasp issue - the kids are terrified of wasps and the tree will be right next to where we eat outside. Do apple trees attract fewer wasps or is any fruit tree going to attract them?

::adopts sagacious expression::

Twiggy - In my unscientific observation, plum trees do seem to attract more wasps, but I suspect that's because the fruit tends to be ripe or over-ripe at the height of wasp season and the wasps are attracted to the fermenting sugar. We get wasps buzzing around the apple tree if there is any damaged fruit on it. The RHS has advice here.

Is there nowhere else you could put the tree?

Wasp traps like this work quite well, as long as you remember to keep them topped up and empty out the dead wasp soup.

Thank you, Maud! No, it has to be against that fence, absolutely nowhere else it can go. It's taken us 2 years to get round to digging the hole in the patio and now I think it's too late to plant a tree! I think I will go for an apple. We have a plum in teh front garden anyway, it's just that everyone in the neighbourhood comes and nicks them!
