Bugs on Pomegranate fruits and Tomato fruit
General None Given
They hatch real small and the 1st 3 pictures are as they are growing, the last I believe is fully grown. They get on my tomato plants and put like a waxy coating on them and they rot from the inside out. Since pomegranates are harder to penetrate I have found nothing wrong with the fruit except when the fruit cracks. I put my tomatos in barrels this year futher away from the pomegranate tree. When they are grown they fly over to the peach tree too, and they are very aggressive toward people.
I'd like to know what they are and how to get rid of them, otherwise no more growing tomatoes for me, it's not worth it since I can't seem to get any to come to full stage, I live in the desert if that helps.
Thank you

These are leaf footed bug, Leptoglossus phyllopus. The adults (the black ones in the images) have flattened tibia (lower parts of the legs, see image). The young (nypmhs) are orange, (see image).
These are true bugs and as such feed by sticking their syringe like mouthparts into the plant (fruit, leaf, stem) and sucking the food. They also inject a toxin and that is the part that causes damage.
Organic control: Use soapy water and a cloth and wash them into a bucket. This is effective as they tend to remain in place when challenged. That gives them the appearance of being aggressive. With a cloth or brush you could brush them into the soapy water.
There are no available biocontrol agents.
Chemicals: this from Virginia Tech (http://pubs.ext.vt.edu/3012/3012-1522...)
"Insecticides should target the nymph and adult stages. Very few insecticides will
kill the eggs of this pest. For most fruit and vegetable crops, a wide range of insecticides provide
control including pyrethroids (i.e., cyfluthin, bifenthrin, lambda‐cyhalothrin, cypermethrin, permethrin,
esfenvalerate, etc.), carbamates (carbaryl, methomyl, oxamyl), organophosphates (such as acephate),
and neonicotinoids (i.e., imidacloprid, thiamethoxam, dinotefuran, acetamiprid, and clothianidin).
Additionally, a number of insecticide products are available as mixtures of some of these different
materials"
I am assuming you are not a commercial grower and dont have a license. So, your option is a product like Sevin (Carbaryl) (someone correct me here please if I am wrong)
There is an entry on Bugguide.net saying chemicals did not work and a useful approach was little bags over the fruits which would keep them at bay

good luck and let us know how it goes.
