Problems with Berries: Soft and MushyIt caused by blueberry maggot fly. This insect, closely related to the apple maggot fly. Deposits eggs just under the skin of the fruit from late June to August.
Eggs hatch into fruit-devouring maggots that later drop to the soil and pupate over the winter.
To reduce the number of maggots that pupate in the soil though the next winter, blueberry need to be harvested frequently and destroy any infected berries can be found.
Another control is to trap adult flies on sticky red spheres like the ones used to trap apple maggot flies.
Hang 1 trap per highbush plant or 1 per several lowbush plants before the first berries turn blue.
