Insect baits

In addition:
SKATOL (3-methylindole), f-la I, mol. m. 131,18; colorless. crystals (in the air and in the light gradually darken) with a strong fecal smell (in a large dilution, the smell of jasmine); t. pl. 95-96 °C, t. kip. 265-266 °C/755 mm Hg; steam pressure 0.26 Pa at 20 °C; solution. in ethanol, miner. oils and other organic solvents, poorly dissolved. in cold water, well-in boiling water. Amphoterene. If necessary. with magnesium compounds and with the latter. under the action of alkyl halides, indolenine derivatives are formed
Skatol is found in some plants, cam. - ug. resin, is formed during the rotting of protein b-B.
Scatol is obtained by Fischer reaction by heating phenylhydrazone propionic aldehyde in the presence of ZnCl2, H2SO4 or CuCl, etc. methods.
Qualities. reaction to skatole-purple staining with Ehrlich reagent (alcohol-hydrochloric acid solution of n-dimethylamino-benzaldehyde), red staining of pine splinters moistened with hydrochloric acid. Skatol forms hydrochloride, t. pl. 167-168 °C, picrate, t. pl. 172-173 °C.
Skatol is used in perfumery in a very large dilution to impart a floral smell to products and as a fixative; in very small amounts, it is used as a component of some products. essences.
LD50 3,5 g / kg (rats, orally). L. A. Heifitz.

and where can I buy it

In chemical reagent stores. Maybe, but I'm not sure...

where can I buy it?

Easier and cheaper-get it naturally)))

We were in the Polar Urals. My friend went to the big one near the tent. They provided themselves with Aphodiuses. Here-where is manure in the Arctic circle? And we got the beetles! Don't make faces.

according to the time of day, I'm going to Chang Mai, the hotel will be in the wild, in the rainforest, I want to ask dung must be caught on a flat area in the light or can be in the forest

And why make a lie? I, for example, not only do not disdain, but also on the labels without embarrassment and indicate - "on (in) human excrement."

dobrovo time of day, I'm going to Chang Mai, the hotel will be in the wild, in the rainforest, I want to ask dung must be caught on a flat area in the light or can be in the forest

In the forest and in the open area there should be different species, IMHO. I.e. you should catch both there and there.

is it possible to use human feces to catch dung beetles the same as cow dung

scarabaeinae, try it, maybe all

is it possible to use human feces to catch dung beetles the same as cow dung

The faunal composition should be different, because a cow is a herbivorous animal, and a person is an omnivorous creature, eats all sorts of filth that is full of emulsifiers, stabilizers, dyes identical to natrural (E116, E 158) and many others.
According to my observations, human feces give much poorer collections compared to cow or horse manure.

sometimes the human body gets something that doesn't fly well on manure.

For example, in the Crimea fly:
Gymnopleurus mopsus,
Sisyphus schaefferi ssp. boschniaki,
Creophilus maxillosus (night only)

Once Savchuk posted photos of these species that fed on the corpse of an animal.

here is an example of a dung trap

When checking traps, many are taken out and lying around. I wonder who does this? Someone wrote that squirrels can. I haven't seen any squirrels. Goats are walking, birds are pecking at something. Maybe the "pioneers" who go to the forest on excursions... But upside-down traps also happen to beetles...

Is this the kind of trap that all dung beetles are caught in? And whether such dung beetles as copra 25 mm are caught, onity

Can be taken out by birds like crows and magpies. Can take out foxes, dogs and other creatures. Pioneers can do it too. There are a lot of critters around the traps.

How to save traps from shepherds, mushroom pickers and other evil spirits
http://molbiol.ru/forums/index.php?showtop...%E2%F3%F8%EA%F3

Some animals - hedgehogs, crows, foxes and all other animals. I have on Sakhalin pulled out glasses in places where there were no people at all.

Some animals - hedgehogs, crows, foxes and all other animals. In my Sakhalin region, they took out glasses in places where there were no people at all.

Now it is very fashionable to install automatic video cameras that turn on from the motion sensor. In our case, it will be possible to find out in detail who pulls out the cups and how. I'm afraid, however, that the camera will be stolen faster

And if you put 100 traps and a camera next to each one, I wonder how much the total cost will be?

I think your approach is too straightforward... In order to understand who the attacker is, just one is enough. You may have to wait a little longer. In this case, time largely replaces quantity, and if you plan the experiment correctly and choose the location, then the time will be reduced.

yes, who just does not pull them out.. who cares, it won't change anything )

and can onites,copra

can onites and copra be caught in such a trap?

And where will their relatives go...???

Dear friends, Tell me. Interested in collecting hymenoptera. Does it make sense to grow umbrella plants on the balcony? Let's say the same dill. Or will there be only a few flights? Or are yellow plates on the same balcony more effective? The house is located next to the forest park.

... good evening to all!
Please tell me.If you catch moths on taste baits, will they not be distracted/deterred by a bright constant light source from near a burning light bait with a canvas?)
If you recommend catching one thing, which method is more effective?

It won't be too distracting. If you catch on one thing-then of course to the light. It's just that there are some species that either do not fly to the light at all,or fly less willingly than to bait.

Good afternoon!!!!!!!
Please tell me if there are any other baits for attracting Click Beetles. I have heard that many species fly to the light, is it true ???

in my opinion, not many fly to the light. Better window traps.

Catocala sponsa and Catocala promissa fly very poorly to the light, but at the moment it is easy to fly next to the lamp. At the same time, they are not distracted or afraid of the light at all.

Pheromone traps for bark beetles are the best, although where to get them is unknown... They fly to the light.

Better soil and, as mentioned above, window.

Soil, in my opinion, is not very good. Not many species are found. In general, we need a comprehensive approach. But the most effective option is windows + manual collection. Light is also not to be ignored.

Good night, everyone!
Who has experience catching hawkmoth on flavor baits?...Or is it more rational to use light traps for this purpose?
If we talk about taste traps, what exactly do hawkmoth prefer in the "menu" or do the "dishes"described in this topic above also work to attract them?

Very many hawks do not feed at all, and those that feed are adapted to feed on the fly, with hovering over the flower. Therefore, the use of baits, IMHO,
does not seem rational. In the light of many hawk moth fly well and very well.

Soil, in my opinion, is not very good. Not many species are found. In general, we need a comprehensive approach. But the most effective option is windows + manual collection. Light is also not to be ignored.

And even more effective combination: window + soil + mowing + manual harvesting = the key to success!!!

well, duc and I about the same thing is better to combine. But if you choose either this or that , I would choose light. although why choose-catch on everything!

Less water, more vinegar, how much is not a pity - (ground beetles climb like crazy, even those that I did not see) Vodka with glycerin can not be poured (tested, expensive, but the result is the same) Pleasant fishing for everyone!
