Blueberry maggot

The blueberry maggot (Rhagoletis mendax) is a species of tephritid fruit fly, which is a major pest of blueberry crops in North America.

Symptoms
Attacked fruit will be pitted by oviposition punctures, around which some discoloration usually occurs.

Treatment
If possible, wild and abandoned plantations should also be destroyed. Systemic organophosphates, such as dimethoate, are highly effective against most species, killing eggs, larvae and adults.
