Custard apple seems more fitting. They are extremely sweet.
Thats unfortunate about the pests. I know that planting hot pepper plants near vegetables helps to ward off insects but I'm not too sure about trees. Do you have a compost pile in your yard? That also helps immensely to "distract" bugs and rodents from things that are growing.
Yes, we have several compost piles/pits/surface layers. I'm not sure, it's a phenomenon of the 90s. When I was a child all the atis were healthy. I've never looked into it, but I'm just letting the tree be until a good mix of other trees comes up around it, to see how it will respond to company.
Mostly they are sprayed with chemicals these days.
