I used to have an issue with these weevils, but for about a year or slightly more they have almost disappeared.
I have a 4 year old sweetheart 8ft x10ft in the ground and a mauritius of the same age a little bit smaller, technically in a pot but grown through in the ground. Both trees used to be decimated by the weevils, with them having a preference for the sweetheart over the mauritius. But now I have no problem with them at all, very rarely I see the occasional lone weevil and squish it of course, but it's almost as though they have inexplicably gone away.
It seems that my trees have reached and passed some threshold where their ability to deal with the weevils (maybe in combination with established populations of predators - I have lots of spiders on these trees, they seem to love them) have dramatically increased.
I don't do anything special to control the weevils, they really just don't bother the trees anymore. Has anyone else had that experience?
Also the trees have flushed normally throughout this period with the young leaves having no issues with weevils.
Hopefully we are in line for a nice cool winter here in S. FL and production will be good.
