I can't help with the ID....but I can confirm having seen this before.  I have had good success with Neem Oil spray to control it.  Mango trees of any size won't really be adversely affected by this. But if you have a young/small tree, it can prevent the tree from thriving.

Its very manageable.  My largest tree, which has been in the ground for about 17 years, is about 10 feet tall.  And,  it can be kept smaller than that with additional pruning.

Pickering or Angie would both due and you'd be very happy with either of them.  Of course, my personal favorite should also receive consideration.  That would be Maha Chanok.

Samuel.....well what would you expect.  Like the license plates say.....Je me souviens........she remembers from where she came!

And my in laws come fully equipped with their VR....or as we call it, RV.

Never tried it, but Murahilin and I tried grafting lots of really excellent mangosteen scions onto both G. intermedia and also G. Livinstonei.  Some of Murahilin's intially looked like they were going to take.  Mine all died straight away. His were not far behind though.  Not sure if the issue was grafting expertise (or lack thereof more precisely) or excessive heat or something else.

And FYI Gerry....its not Possum Arse carambola.  It's Possom Trot.  There is, or at least was, an old time nursery in Miami called Possum Trot Nursery.  This was a seedling selection of carambola that was made by the folks at that nursery.  Its a pretty good fruit and nicely sized and shaped.  Many people that have tasted it have said that it compared favorably with the best carambola fruit they have had.  Possum Arse.......lol...indeed.

So let me say that Tony, if you have experienced rotten taste when eating black sapote, then the fruit was probably rotten.  The fruit that we ate when Lycheeluva and Murahilin were over was a small fruit and despite apparent observations to the contrary, it was not fibrous.  The taste was not like mango bloom.  It has a mild sweetness and rich sort of vibe which is somewhat piudding like.  I have two trees.  This is from the larger of my trees and was an airlayer that I bought at one of the Broward Rare Fruit and Vegetable Council sales about 17 years ago.  I have no idea where the original plant was from which it was layered.  However, this fruit does have a representative quality in flavor and texture is better than some I have tried.  I also have a small tree of the Joyner Everbearing (a graft that I did myself from material I got at Gene Joyner's place).  I have to agree with Oscar that Black Sapote is worlds more flavorful than Coco Plum.  Although I have some Colombian friends that swear that there are sweet ones, I have never encountered any. They are grown in landscapes all over our area and I have literally tasted thousands of fruits, both dark and while skinned.  The best ones are like sucking on bland gelatinous cotton....if there were such a thing.  However, I keep tasting. One day I might be able to report a finding of something better.

Murahilin tried to get me interested in cherries for my yard.  He claimed that there were these new, low chill varieites.  Frankly, he severely tempted me as I would kill to be able to grow cherries.  I am very interested in seeing how you do with these.  I will appreciate some photos updates....when you get the chance. From what I have read, however, I might as well try to fruit durian as the least of the chill requirements for these cherries seems to exceed the meager chill hours that we get in Zone 10B.

Bien venue, Samuel.......check out this new forum with all of its new, much more up to date options and fomatting and you will see why this is light years better than the old Garden Web Forum.

Gerry...my apologies for the mistake.....but the beauty of this new forum is that you can edit your posts after you post them.  So I did.....now you can delete your post, if you so choose.

I still have lots of Monroe avocados on my tree.  Excellent avocado....one of the best later season Florida fruits.
