They usually enter the stem end of the fruit where you can see some frass or light brown grounds left behind by the larva or worm.

 These can be easily controlled with sprays of either spinosad or Bt, both of which are organic sprays. Follow label directions and apply regularly. Add a surfactant such as a spreader/sticker or small amount of unscented liquid detergent. Spray the entire tree, particularly the fruit.
