Small Round Holes in Tomatoes is Tomato Fruitworm

Q. I found about 4 to 5 tomatoes with holes in them. I have been getting ripe tomatoes for about 30 days and found these with holes in them during the last two days. I searched for bugs, eggs and leaf damage but did not find anything. Any ideas?
Probably tomato fruitworm damage

A. The 3/8-inch diameter and larger holes in your tomatoes look like damage from the tomato fruit worm. These are worms, or caterpillars, are about an inch and a half long and 3/8 of an inch wide. They eat holes mostly in tomato fruit, usually when they are green or when they turn red but are still hard or firm. Frequently the fruit becomes rotten from these holes.

Organic sprays of Bt or Spinosad when the fruits are starting to form will prevent this.
