Insect baits

Does anyone in our area already bait night scales? Two days ago I forgot an open jar of fermented pear jam in a birch tree. And today I knocked out a bunch of broken shovels the size of N. pronuba.

Catokals are already flying to bait even in Moscow: -)

Good evening
Advise who knows and uses, fixator for beetles in crown traps

I use ethylene glycol. I buy a can of antifreeze , which is usually a solution of ethylene glycol with different additives, and add 100 grams to each wine trap. Tested in hot countries, traps hung for up to 1.5 months and the material is of excellent quality, not rotten. The only negative is that large beetles dry very badly after spreading, the joints remain mobile, but this is a solvable issue.
You can use salt, but after it, the beetles are washed for a long time and often there is a plaque.

Thank you so much for your reply!
And with the color of beetles from this solution, nothing happens?

No, the color didn't change.

Ethylene glycol is quite toxic and gives the bait a bitter taste. It is justified if traps are rarely checked, or there is a risk of vertebrates eating the material. At the same time, it is better if it does not fall into the bait. For example, the bait is installed inside the trap in a perforated capsule-shifter, on a rod above the bottom, and the bottom is filled with a retainer (10% vinegar, with or without ethylene glycol, or another mixture). Beetles are attracted to the smell of bait and, in attempts to get it, fall into the retainer. The required concentration in terms of pure ethylene glycol is 1-2. 5%. The 2.5% concentration combined with vinegar and glycerin preserves the material for up to 2 months, even in land traps. The material from EG must be washed before being put into storage.
Regardless, glycerol can be used in the same concentration. It does not spoil the taste of the bait (rather, it improves), reduces moisture loss and has preservative properties, although less pronounced. It is preferred for simple traps with open bait and relatively frequent checking. A concentration above 3% is undesirable, otherwise even after washing the beetles remain elastic and shiny for a long time.
To prevent fungal damage to the bait, you can use propionic acid in a concentration of o,2-0. 5%, or worse, citric acid in a concentration of 1-3%. But they inhibit yeast fermentation, so they should only be used on baits that do not require maturation.

Where is glycerin sold and in what form ?

Where is glycerin sold and in what form ?

In the form of glycerin . Sold many places. Small amounts (up to 50 ml) are easiest to buy in pharmacies. It costs a penny. I've been buying good glycerin lately here:, but there you need to take from 2 thousand rubles. Pure glycerin is better. A number of washrooms also have it, but there are many other unnecessary things. Search for "food grade glycerin", "100% glycerol", etc.

Katokals are already flying to bait even in Moscow: -)

Come on and what are they? Well, very interesting.

Come on and what are they? Well, very interesting.

Moscow - fulmineya, Volgograd two weeks ago-fulmineya and promissa. There are probably a lot more species now.

Today I checked my hot spots - the whole forest stank. On catocalories - full 0 Too early for them yet.

It may be useful to someone. I visited relatives on vacation, they have a small farm in the village. After cooking the curd, they pour the remaining whey into a huge aluminum pot outside. In a couple of days, this pot is full of all sorts of moths and plus a few hawkmoth. And in a bowl of sour cream for the cat constantly flew and stuck in sour cream leptura

How can you catch ontofagus (kaloedov) in the Moscow region? Of course, I can guess about the bait, but I don't know in which biotopes to place it.

I think this bait has already been placed in all the biotopes for you. It remains only to pass and poperevorachivat stick. They gather there from below without any traps. In addition to kaloedov at this time of year, you will definitely find various interesting staphylins and carapiuziki.

I decided to try for the first time to cook a brew for bronzes. I bought three 1.5-liter bottles of cheap beer, three liter boxes of cheap fruit wine, a kilogram of sugar and live yeast. Is it possible to make something worthwhile out of this, or are the ingredients so-so?

The main ingredient is sourdough from oak. And with the yeast that you bought, a different brew is better

Yes, for bronzes, it's enough just to mix beer with sugar and salt, you can also add spoiled honey or jam there, but it's better to take beer unpasteurized, draught, at beer points. There, they have a drain formed during the sale process, they pour it for me for a nominal fee, or for free, where I buy beer on a post basis (I used to buy it, now I quit alcohol altogether). You can also use wine with sugar and salt, which is used as a preservative. No yeast is needed, and there is no need to wait either, just mixed, dissolved (carefully, foams), hung up on the same day, in the sun it will turn sour and ferment itself.
The most important thing here is the choice of location for the trap. If it turns out to be installed almost on the top of a tall, sprawling oak tree standing somewhere on the forest edge, then the bronze will be 100%, and if in the dark thicket of the forest and below, then the stump is clear that nifiga will not be caught there.

For some reason, in 100% of cases with this approach, I had a large bolt and a lot of small leafmakers. I threw it to the top more than once. No, if you are lucky and the sun will ferment the right oak spirit, and not moonshine, then, probably, there will be. But I've never been so lucky. Even during the sacred rite with oak leaven, it is not necessary once in a while. And without it-in 100% the product asks for its smell in the distiller, and not in the trap. Well, or maybe there are so many bronzes in your area that they are suitable for such a smell, but you should not generalize.

well, in general, I wrote about how I do and how I catch, so to speak, in fact. I've been using this method for 8 years, since 2012. wanders in principle always the same.
standard composition-draft beer (tikhoretsk, khadyzhenskoe, bavaria, etc.)+table salt+ regular sugar, sometimes I add honey or jam, sometimes wine.
For installation, I choose well-lit clearings or the edges of an oak forest, put them on tall oaks, beeches or hornbeams, according to the principle of the higher the tree, the greater the profit.
true, I do not throw traps, I myself am a tree climber))) at the same time, a good workout when all the muscles are working

You gave a 100% guarantee, and I added a comment in response. And if you have it already at home wandering, or after hanging out? And what does it smell like? Beer, moonshine or as on oak sochniki?

Well, as I already wrote, I prepare the bait just before going out into Nature. Once I prepared it a couple of times in advance, but I didn't like it, because the eggplant was inflated overnight, and once it even broke and the liquid leaked (or the cork was torn off then, I don't remember anymore). The smell is always about the same, very pleasant, not sharp (before the insects that get caught do not wander there). At least it doesn't look like moonshine, but it doesn't have much in common with oak juice, which has a sour, rather pungent smell. Yeast just the same and will give specifically alcoholic fermentation imho. And it's not really needed there. I've never used it, and I don't intend to. But there is one caveat - I almost always use draught, unpasteurized beer, which I take at beer outlets, and since I am not only an alcoholic, but also a beggar, I use the drain that is formed in the process of selling beer, which is poured to me almost for free or even for free and it is initially already far away not the first freshness (as it was by mistake slurped instead of beer).

And it doesn't start catching interesting species in large numbers on the first day, right? Is the smell of the first day very different from the smell of the second and subsequent days? I suspect that your brew gets the right microbes and the right smell already at the location of the trap, mostly from drowned people who used to feed on sochniki.

This method is not suitable for me - I catch live fish on a sponge soaked in mash, on the second day everything dries up and does not work. Therefore, the right smell should be brought immediately from home. The smell of beer does not roll, not to mention the smell of moonshine.

Yeast is different, and, accordingly, aromatic impurities to the ethanol released by them, too. Bakeries and pubs don't roll. And then there are other microorganisms. The fact is that with sourdough from oak juice, oak twigs, from the surface of red oak acorns or gledichii fruits, if you manage to take root it, the smell turns out exactly like that of oak sochnik, only much stronger. And everything is flying at him with terrible force. Sometimes you don't have time to move away from the trap, and it's already there. But, unfortunately, it is not always possible to conjure this wonderful fragrance.

Once I smelled a very similar powerful spirit in the bus cabin, where Bukharik opened a can of Revo energy drink. Perhaps you should try to catch this stinker, as a stable substitute for oak mash.

To be honest, I don't even know, since I usually fill out traps on the weekend, and check them out about a week later. so it is quite possible that everything happens as you write. we catch standard types of bronzes - most often Speziosa, Affinis, Kuprina, and sometimes Aurata. During the season, you can come across Cervuses, Cerdo barbels and several types of small flower barbels. Sometimes and only in certain traps rarely come across Gnorimus Balthersa, but as a rule always isolated. And the rest - hornets, butterflies, including Catokals, but which of course are no longer usable)))

phew, beee... although I am a buharik myself (currently not a drinker, but as you know, there are no former alcoholics), I would rather stop drinking altogether than pour such a poisonous abomination into myself, like all these jaguars, energy cocktails, etc. I don't even understand how you need to be a pervert to drink this))

Well, I would also be careful not to drink fermented oak juice. And the smell of a wet trap with hundreds of drowned people, let's just say, for an amateur. But insects like it. So it is possible that you will like the stinky in cans, you should try it.

Oh, I'm delirious, only alive...

live ones were ordered to me already, there was a very profitable exchange, of course, I tried to catch them for fermented bananas, for this I made a gruel with beer and jam,but the experience was not successful. only the stinging hymenoptera crowded all this bait in a tight crowd, and not a single bronze was there. and after a couple of days, everything dried up there...
what do you have against oak juice? well, just before it ferments? the same birch and maple are collected and drunk with might and main, why not try oak, it's not anchar in the end)))

And before it ferments, it doesn't really flow naturally. And it is not worth mutilating oaks for the sake of getting fresh juice. Oak generally tolerates injuries not very well, often initiated by fungi, and dies, and after 10 or more years. On natural sochniki, the juice flows out ready-made, sometimes it already splashes like champagne.

But I wrote this to the fact that if something does not smell particularly appetizing for a person, then this is a reason to refuse it as a bait for insects.

Bananas are a strange thing. When I caught the first live bronzes and put them in a terrarium together with oak branches, on which I pinned banana slices, the latter very quickly and powerfully smelled the right smell. I don't know if it was the branches or the beetles themselves that had previously consumed fermented oak sap. And so it was until the fall. Then, apparently, the culture of" aromatic " microorganisms was interrupted (the bananas stopped smelling) and the next year I could not get it, although I even introduced inoculates from the fruit trees, not to mention different branches. Recently I tried to repeat it - again a bummer. The irony is that proper fermentation suddenly occurs when it is completely useless (for example, in the winter in a tray with sprouting acorns), and when it comes time to make traps, it does not want to.

Live bronzorvok can be caught with a net, only long. And it usually takes a long time to find a suitable place where the beetles sit low enough. But if you can climb trees, it's easier for you.

There is such a recipe for bait for bronzes: one banana, one apple is crushed in a blender, water is added to a convenient consistency, 2-3 tablespoons of sugar, yeast, just before using a little salt, about a teaspoon. Bronzes fly even in cloudy weather.

and why is salt here? if you catch the living? well, if you do not live, then we also climb on sour beer only on the way) wine and beer are easier to make and no yeast is needed there.

Does anyone use pheromone traps? Maybe you have experience buying pheromones or general semiochemicals?
