Jakefruit,
Thanks for the research. I'm always learning from others here. I haven't seen that insect fortunately. Peaches are the most challenging fruit I grow, I get why they're one of the most highly sprayed fruits.
I have found that the healthier you can make your tree, strong rootstock, proper nutrients, and right growing conditions, the less insect damage you get as the trees mature. Peaches benefit from extra calcium along with your usual macro/micro nutrients.
