Pest and tree heath

Eric starts with ...
Hi guys,

I have a few pest eating my precious trees could you help me identify them and maybe find a healthy way to control them? Every trees plant are done as follow: We have clay soil so i dig a large whole, add, gypsum, blood and bone, mushroom compost mixed with coarse sand and imported loamy soil, make a mount of it, plant the tree, water, cover with cypress mulch.
1- I got ants walking inside the soil around the trunk on my Apricot low chill. I put diomateous Earth on there path but it doesn't seems to make much effects.
2- My chestnut Reilly looks like it's dead. Had buds showing during winter then zip nothing else. See pix. its actually on constant drip system with the tree wrap containing water in it.
3- My cashew nut tree (not from your nursery) suddenly it's leaves crumpled. See pix.
4- Peach and Brazilian Cherry leaves have families of insects black and white I never seen before with little hard white eggs below leaf. See pix
5- Orange tree has an ugly caterpillar every now and then. See pix. I usually squish it on the leaf and leave it there.
6- Same orange tree I think its leaf miner chewing the leaves? See pix.
7- Same orange tree a single insect i am unsure of identity. See pix
8- On the pear tree, just an insect I am not too worried about but I am not sure. Just in case you identify it as a pest. Let me know.

I have renamed all pictures for easy look.

In a previous questions i asked about the Raspberry heritage bareroot and what to do with the primocane to cut or not to cut. I left it as told and the whole bed of raspberry is blooming. Just need to get the fruits to mature. Thank you.

I wish you a merry christmas. and see you in the new year.
