@ Bob:
Thanks Bob! In fact the garden is full of a kind of green crickets similar to grasshoppers, they resemble this one, it is called "tettigonia caudata":
Mine, they jump from one plant to another, I've captured some, but I don't think they're so voracious, otherwise I wouldn't have leaves for a long time. I also saw a few light brown crickets, but I saw it very rarely and they are really hard to catch.
Are your crickets : green or brown?
@ Pier:
Thanks Pier! Unfortunately,, besides the insect of the photo, I don't see any other insects, usually grasshoppers arrive here in autumn and have a gray-brown color. Now the second growth is starting and I hope to understand what the leaves eat.
@ Charly:
Thanks Charly! I have a few small holes in every leaf and also in the leaves of vegetables, but some tobacco leaves lacked almost half a leaf! Fortunately it happened at the end of cultivation!
Update after the 14th Week in Garden
Hello everyone!
Sunday, August 4th 2019, the 14th Garden Week for my plants is over. During the week, Thursday, in anticipation of a strong storm, I finished the harvest of the Top-stalk leaves of the Costello harvesting them with the whole stem hanging them in the cellar:
Usually, for me, the Top-stalk leaves are more difficult to cure by harvesting them leaf by leaf and bagging them, so I treat the Top-stalk leaves by hanging the stalk so that the leaf "dies" slowly without the risk of drying green or other issues.
But this year, those few top leaves that I harvested and bagged, they treated very well! Like the other leaves and perhaps better: a beautiful canary yellow - unfortunately I didn't take photos so you have to believe me on the word

-..
So, now I have the temptation to remove the leaves as soon as the green clears and bagging them after washing them. All this is above all to have clean leaves, I hate having black, sticky fingers every time I handle the leaves.
A few words about Criollo
This is a strain that I had difficulty treating yellowing in the plastic bag, part of the leaf turned brown and "sweated" while other parts of the leaf were still green. And this is the typical result:
So, about three weeks ago, I decided to harvest the plants with the still stuck the Mid-stalk leaves and hang them in the cellar, also because I needed that space in the ground to transplant Brussels sprouts.
For now the cure in the cellar is going well, no signs of mold, hanging plants can be seen on the right in the previous image, that of Costello hanging in the cellar
And these are the first dry leaves stripped on Sunday:
The color is uniform, very different from the yellowed leaves in the plastic bag: this is a card-box with Low-stalk leaves and some Mid.stalk leaves:
I will speak in the next update of how I am treating the Prilep.
Bye Bye
