Phoenix canariensis pests

This is my first participation in this forum. I give you the good morning
We have a serious problem with Phoenix canariensis in a garden in Queretaro, Mexico. There are 21 of which 5 are already practically dead, and another 3 or 4 have some symptoms of pest or disease. We found some larvae and pupae that may be the cause. I'll show you in the following photos.
Yesterday I was looking for possible causes. No I did not find palm weevil. I found some larvae and pupae. Pupa size is between 2 and 3 mm. and larvae between 4 and 5 mm. The pictures of the palms are the April 4 and larvae and pupae are from yesterday.
I found only one adult, but I'm not sure he is part of the problem. It is in the upper right and is 2 mm.
Could you help us with the diagnosis. We would find a way to stop and fight early, before they continue destroying more palms.

Just looking at this really quick I think I see secondary infestation after the plant is dead or rotting. To me it looks like Fusarium Wilt in the second palm and the bottom palm. Maybe Fusarium is killing them?

The winged insect looks like a termite.

I'm sure is a fungal infection.

The larvae is tipical in death palms, it is not the problem.

You must spay systemic fungicide and if is posible, water with the fungicide.

The fusarium infections start in the roots.

If the palm is infected, is very dificult save it.

Always the best is destroy the infected palms and make preventive treatmens in the healthy palms.
