I think it just stressed itself out trying to carry a load of fruit. The burnt leaf margins are curious; not sure what those are from. I might give it some time to recover from trying to hold a crop when it was already marginally healthy.
As long as you can get the tree to start growing (vigorously), the weevil problem will be mitigated. Right now, you have a few dozen leaves that are bearing the full brunt of the weevil onslaught.
