You'd need a uv-b tube and some spider mites - ain't got any at the moment, thank fook lol
Put the spider mites in a container of some sort then apply the uv-b and see what it does to them. How much, how long is needed before it effects the mites and will the dose of uv-b adversely effect the plants?
Or use the uv-b tube and manually run it through the plants to expose the underside of all the leaves and the critters to uv-b light
Obviously it would be easier to do this if the plant was defoliated!
I am sure someone on here can help you out. lolI wonder if there is a place where you can get spider mites
A spider mite is technically classified as an arachnid so maybe you answered your own questionDid you read also the science paper that it is referring to?

It is is very unclear for me.
For example it says this: Lethal effects of UVB have been reported for spider mites, in which UVB irradiation strongly decreases survivorship and egg production. However, there are no reports that describe lethal effects of UVB or UVA (315–400 nm) on insects, although UVA irradiation slightly decreases adult longevity in the lepidopteran Helicoverpa armigera.
A spider mite is an insect... so what do they mean?
I had to visit Wikipedia for all this informationA spider mite is technically classified as an arachnid so maybe you answered your own question
Insects and arachnids are both Arthropods so you could look up uv affect on arthropods
I have heaps of spiders around my house you can have some big hairy cunts too if you want to experiment on them.I had to visit Wikipedia for all this information
Will do more research as it is an interesting field.
As a specialist (you know all the official words at least)... would there be a way to get spider mites or other mites somewhere?
I read on Wikipedia that the mites that are hurting plants are Red Spider Mites and the Two-Spotted Spider Mites. You can fight them with predatory Mites. If I would buy those predatory mites and do the test on them, would it be the same? Or is any specific type of mites different (I mean will one species be killed by UV-A and the other species not?)A spider mite is technically classified as an arachnid so maybe you answered your own question

I'm allergic to the uv so I hire in a professional .....I have this bulb used in a handheld to protect the plants in my greenhouse. Oct./nov. it get's pretty wet here and usually you get but rot and PM like crazy. I've lost a whole run because of bud rot and 3 days before there was absolutely nothing.
With the painter suit, the thick gloves and the sunglasses I surely looked like some sort of mad professor, lol!
If you have already spider mites or something similar it will probably take a while until they dissapear. The eggs they have hidden under the leaves are may not affected but the mites will be affected and with the time their eggs too. So depending on ambient temps maybe between 20 and 60 days. These beasts reproduce themself pretty fast with 30°C ambient temps so it maybe takes two or three generations.
I have usually no mites or other insects in my groom cuz with neem cake and some diatom earth in the soil you can keep them away easily. Neem cake aginst all sucking insects in the arir and diatom earth to destroy any soil living insect like some sort of tripse or fungus gnats larvea. These bulbs also emit some visible blue light so its no wonder they will fly around if they can. It maybe needs more time like with more harmful UVC but over time insects will for sure dissapear.
It's better used to prevent your groom against any manifestation as to remove/kill insects immediately. And if you want something with even stronger effect you can install a small 11w UVC ponds clearer bulb running24/7 inside the air intake hose. Such systems are used for clean rooms to keep them free from any flying pathogens or spores. You get them as 1U cfl bulb, 7, 9 or 11w but I'm sure you can get even bigger ones. But these bulbs are potential dangerous so keep them away from children. But when you have you tent in a cold garage or wet basement they do a pretty good job.

In my garden UV via agromax pure uv was not remotely as effective as micro biological innoculation of phyllo and rhizosphere.I have this bulb used in a handheld to protect the plants in my greenhouse.

Near UV means 400-410nm, that's so called black light which has fluoro effects(disco, pinkish nail, teeth, ...).In my garden UV via agromax pure uv was not remotely as effective as micro biological innoculation of phyllo and rhizosphere.
For some fungus UV is a signal to induce sporulation.

Effect of light on the growth and sporulation of Botrytis cinerea
Sporulation of Botrytis cinerea Pers. ex Fr. was stimulated by near ultraviolet light. Infrared, red and yellow light were also slightly effective, but blue and green light were ineffective.

But doesn't it hurt the plants as well?i just blast them with my diy uv-c clean light a few times in veg
