I know nothing about growing blackberries but have an unknown thornless variety growing in Kona, Hawaii; they were ravaged by Chinese beetles, so I have completely netted an open air quonset frame they're growing in (with canes 1.5cm diameter and 25ft long!). I've had a few delicious berries on last year's miniscule canes (before I started treating the plants well). Now the Chinese beetles are vanquished but am wondering if excluding bugs (AND bees) via the netting, will I have no more berries (i.e. do potentially self-pollinating blackberries still require bees?). Thanks, aloha.
Do Blackberries Self Pollinate?

Most cultivators of Blackberries are self-fruitful and do not need pollinators.
Honey Bees are naturally attracted to cane berry fruit and wind also aids in pollination.
I have listed a few links for you with more information.
