Toxic gases and efficient catching in tree crowns

I have long read and seen on TV channels about the study of the crown fauna of trees in the tropics. But it is there that most of the species diversity of insects lives. People in gas masks with funnels and balloons on their backs in the morning, during the rising air currents, walked through the forest. Noxious smoke billowed upward. From there, thousands of new species rained down. They were caught by huge cones and simply spread out sheets. The amount collected was simply staggering.
Where would you get such a gas installation? In stores for summer residents, they offer only banal sprayers..

This method seems to make sense only in the tropics. There, the death of a dozen kg of insects will not play a piano for populations and species. But in our country, for example, this is a crime and also not very effective (I think so).

As for environmental OCD pollution, this method of collection is usually used for scientific purposes, and it is also associated with other types of pollution (chronic!) not comparable.

Ether will not work (too flammable), rather chloroform. In this generator, the pipe is very hot, and the creation of smoke from the insecticide occurs under the influence of a small explosion of fuel (a thin trickle of poison is sprayed to the state of smoke by air).
I think the chloroform will just evaporate very quickly...

P.S. I just reread it and realized that I didn't explain it well on my fingers. I'll try to find a disk with instructions from this device at work tomorrow and show you a picture.

Neither ether nor chloroform will work - at operating temperature, the generator will turn into a flamethrower.

You just forgot about the banal carbon dioxide. From it, insects do not die, but fall asleep, and then wake up quite normally.
True, warmbloods behave "somewhat" differently...

Colleagues, the method of processing crowns with SwingFog devices (SN-50 and others) is an excellent method that gives fantastic results (especially in the tropics, but also in the EU (Latvia, Germany). The method is harmless to the environment - peritroids decompose into water and carbon dioxide within half an hour. And "tons of insects" do not die at all!!! They come to life and run away. Except for those that you can collect in an hour or half an hour. Peritroids only temporarily put invertebrates to sleep (as well as frogs, lizards, and other crabs)! I smoke myself for a long time and professionally. I can post photos of what it all looks like, and videos too. If you have any specific questions about the collection methods, please write to us and I will be happy to answer them. And such species that fall from the crowns or cracks of the bark, such other ways to catch oh, how difficult!

In fact, descriptions of the technique exist and have long been published in Western journals. I'll look for photos at home and put a couple of them on. What seems to be the most important thing? Security! Yourself (the importer). surrounding people, as well as the environment. Regardless of the model of the "dymovik" used, it is necessary to observe increased vigilance in terms of fire safety when working with it. In short, the "dymovik" tends to turn into a flamethrower that shoots fire (i.e. burning kerosene) to a height of up to 20 m (depending on the model). Accordingly, it is easy to burn down a tree (or an entire forest) if you do not follow the precautions described in the manual for using a particular unit. You should always have a couple of dozen liters of water with you (for extinguishing) and an assistant who will help in case of problems. You also need a first aid kit. Although nothing like this has ever happened to me, I have witnessed the most unpleasant moments when fishing with a "dymovik". The area where smoke removal is carried out must be prepared in advance - grass, roots, and decks must be removed. This will make it easier to collect fallen insects, and escape routes will be free for you.

And where to buy peritroids is not for me. You can buy them here in the EU. As for you, I have no idea.

You can buy pyrethroids in a container of one liter or 5 liters of ready-made solution or concentrate, so you need to take it. They sell offices for the control of household insects. But as I understand it, they prefer it for cashless payments.
The composition is classic-permethrin or cypermethrin. you can look for small vials in OBI-type stores, but the pyrethroid concentration is specifically reduced for safety reasons. And in the field, it is still better to use a slaughterhouse.
However, do not expect any miracles, immediately and a lot, from pyrethroids. This is still a rather complex type of fishing, which requires persistent and massive application to get a total result.

Here, in fact, is my short note about this method on the website of coleopterists (provided with several photos): http://www.zin.ru/animalia/coleoptera/rus/fogging.htm

There is a summary of the essence of the collection method and about chemicals, too.

And the smokestacks themselves are better to take in Germany, swingtec company, www.swingtec.de. It sells pest control equipment (the main use of "smoke detectors") and sells these units at the manufacturer's price. Various units are offered - from portable (such as SN-50, which is considered optimal for individual fees), and stationary (which are mounted on a car platform and from which, for example, in the United States, reservoirs are fumigated to kill mosquito larvae, etc.

By the way, the features of using this method include: 1) you need a complete calm (so that the "smoke" lingers around the object being smoked for a while) and 2) there should be no rain.
