I wish I knew more about peaches. Having grown up in S Florida, I just don't know that much about them because they are not typically grown down here. If anyone can help me positively identify the type of bug that is ruining my peaches from the inside out, please leave a comment or email me. Based upon preliminary research, I think I need to spray the peach blossoms next year, so the larvae don't crawl into the blossoms then lay dormant until the fruit ripens. This is so frustrating because the tree has a few hundred peaches right now and they ALL have these bugs.
