Plum Curculio Burrows in Plum Fruits

Q: Why do all of the plums on my plum tree have bug holes in them? The tree was full, but the plums were no good. 

A: Damage to the plum probably came from the plum curculio, a weevil-like insect. It sticks its nose into the young fruit and feeds, and then lays eggs in the wound. The young curculio changes to a grub that feeds on the plum. They can be controlled with a fruit tree insecticide.
