Default Odd Rasberry Problem

I have Red Latham - 2nd year which should mean I am getting fruit.
The only thing I got was hundreds of 1 to 5 'kernal' berries - really
strane looking to see a rasberry with only one kernal. Not sure why
the berries did not fully fruit. The only thing I noticed was that
during pollination time there were dozens of huge bees (not honey bees
- never seen this kind before) on the flowers. I thought they were
doing good but I suspect that they harvested all the pollen thus I
have no berries.

I guess I will cut all the fruited canes down and thin out and top off
the new canes for next year. This crop is a wash.

Any clue what would cause this.

I have some other fall gold and other red rasberries and they are
doing fine but are in another spot and did not get bothered by the
bees. Makes me want to net my Red Latham rasberries next year.

I am near the fruit belt of Zone 5 around Lake Michigan in NW Indiana.

Any comments welcome.

Rick

Poor pollination.

Huge and black? May have been carpenter bees. Huge and 'honeybee'
colored? May have been bee-imitating flies. Not the most effective pollinators
of raspberries. (I have been lucky to have had honeybees working my plants.)

Poor pollination can result even with plentiful bee visits if the relaltive humidity
is too dry. Too much rain during the flowering period is a problem as it limits
the number of bee visits.

Yes, huge and black. Humidity has been dry this year and we have not
had too much rain in the last month either. It looks like it could be
a combination of all the above. I wish I could cover the rasberries
next year to prevent the black bees from comming back but then I risk
some pollination loss. Live and learn.
