Hi Juanse:

The wild blueberry is different and because it is not planted
there are no late "varieties", but there are late clones found in
patches through the field.

I really do NOT have a very good idea, but I can offer this:

1.  For another year you could get the growers to investigate
the product sold by Pherotech (look it up on the net, it is a
company in Vancouver, Canada that makes insect pheromones)
for spraying on crop to increase the bee pollinators.  I think
that nasonov gland pheromone is the main ingredient.  The
growers here do not think it is economic, but the average
yield here for wild blueberries is about 2,500 kg per hectare
with a maximum of about 7,000.  I think it must be higher
with highbush blueberries.

2.  It does work here if I have two fields more than 2 km
apart and I switch the hives between fields.  The bees are
forced to reorient and the first crop they see/smell is
blueberries.  It only works for a short time and it is a
lot of work and so I charge extra to do it.

If you happen to go to the sprayed apples to see if the
bees are working them could you post to the list.  I would
be interested to see if you find that they avoid sevin
sprayed apples the way they do sevin sprayed blueberries.
