TheNewLandscape, I hope you get some fruit to form for you soon. Your planting zone there should be suitable for this heat loving tropical plant. Mine, unfortunately, died in this past Winter and never came back. I left it out in the pot because I simply had too many plants to move inside my home during the cold this past Winter. I also noticed when mine fruited last year, there was a lot of white cottony stuff on it. I think it's the white flies. For some reason, the white flies love to attack it. I harvested a couple of fruit before the infestation got worse. We all loved the taste of it, but it was too delicate plant to have for me around here. It would be nice if you have some pictures to share of your plant. Have you thought of using a brush to hand pollinate the blooms? I think I did that to my blooms as suggested by some forumer in this thread here and had some success to get fruit formed that way for me. Hope to hear some good news of your fruit forming for you soon.

Well it appears to be the caterpillar of some kind of butterfly or moth. There are thousands of species so the fact it doesn't look like your other ones doesn't signify. The Insect Forum might be able to help, or The Butterfly Gardens Forum

Hi John, are you saying you have sugar apple seeds to give for SASE?

Start using soil building. Look up chop and drop and permaculter. Also use biochare. It takes a few years to build but it is worth it and it's better for your trees. For now I would use a 10-10-10 and start putting spent coffee grounds around the tree.
