Just some thoughts and I am way out on a limb here so shoot 
anything down in flames.

Cameron have you noted the day-night temperature differences? 
80-55 deg F is indicated as ideal by P. Bosland. Peppers of the 
World.

If they are going to drop I don't believe pollinated or not is 
going to make any difference.

Small brush, Qtip, fingers, insects or any other means should
not make any difference if the pollen grains are transferred. 

Possibly self incompatibility plays some part in no fruit set 
but if the insects (bees) are busy manual pollination is most 
likely a waste of time.  

My three plants are full of flowers at the moment but
unfortunately they will have to be transplanted in my move to
another house.  Time will tell how they recover and I'll report
on any fruit set.

Many plants exhibit such characteristics see hops which has a 
narrow latitude band in which it can be grown. 

Anyone with any experience of second or third generation plants 
becoming aclimitised to local conditions?
