Features of light catching

And this is not a blockage, these are specific answers to the question of Wave Storm, whether the season has started, or whether it's too early yet. The bottom line is that in the surrounding regions, moths flew (to the light or just like that-it doesn't matter), so it makes sense to shine. This information does not have to be personally useful to You

In the Kharkiv region, just a few days ago, xanthomelas were already flying in full force...

And this is not a blockage...The bottom line is that in the surrounding regions, moths flew...

Uh-huh, especially about the departure of polychrome flowers and it is in this topic. Such "specific answers to the question", perhaps, for some time have become relevant only in this topic http://molbiol.ru/forums/index.php?showtop...0&#entry1659658 , which has long been virtually a "conversation for three". However, this is my opinion, which coincides, as you can see, with the opinion of Djon (a).

Dear colleagues! I apologize if there were already similar questions in the topic, but I will still ask: maybe someone had experience using black UV DRV lamps like this: http://lipetsk.regmarkets.ru/product/468cc...872caa413c6bfc/ can you tell me how effective they are compared to DRL 250, and whether they affect the eyes and skin? Should I buy it?

1) Only stab DRL are quite effective, I am not ready to enter into disputes about the security of these devices, with elementary protection and the ability of the "catcher", the thing is completely safe. This is followed by entire DRL (preferably Philips). Unbroken DRLks are also very good, sometimes they turn out to be no worse than "beaters", it all depends on the fishing conditions. The Blacklight lamp on the test behaved much worse than the entire DRL (under equal conditions, two screens were 10 m apart). The experiment was a one-time one.
2) Any blue light negatively affects the eyes, vision can be "planted" by passing the summer in sunglasses with blue lenses.

AndreyU5, thank you for the detailed answer. The usual DRL is good, no doubt, and I use it, like many, but it also has a number of disadvantages. Paired with the throttle at start-up, it consistently overloads my 0.7 kW generator. Yes, and many species "do not bite" on it, although they literally fly nearby and feed on flowers. Therefore, 2 main thoughts: reduce the load on the generator by getting rid of the throttle and lure those who do not respond to the DRL.
I thought about using the DRV 250 in conjunction with such a black DRV. Can you say anything about this combination?
Can someone else respond?
Thanks!

but it's really hard for me to imagine which of them can develop under the influence of blue light.

For the especially gifted, "Blue light is the shortest-wavelength range of visible radiation with a wavelength of 380-500 nm, which has the highest energy. The name "blue light" is essentially a simplification, since it covers light waves ranging from the violet range (from 380 to 420 nm) to the actual blue (from 420 to 500 nm). Since light waves in the blue range have the smallest length, they, according to the laws of Rayleigh light scattering, are most intensively scattered, so a significant part of the annoying glare of solar radiation is due to blue light. It is the blue light waves that are scattered on particles smaller than the wavelength that give color to the sky and ocean. This type of light scattering affects the contrast of the image and the quality of distant vision, making it difficult to identify the objects under consideration. Blue light is also scattered in the structures of the eye, impairing the quality of vision and causing symptoms of visual fatigue."
The harmful effects of blue light on the retina were first proven in a variety of animal studies. By exposing monkeys to large doses of blue light, researchers Harwerth & Pereling (Harwerth & Pereling) found in 1971 that this leads to a prolonged loss of spectral sensitivity in the blue range, resulting from damage to the retina. In the 1980s, these results were confirmed by other scientists who found that exposure to blue light leads to the formation of photochemical damage to the retina, especially its pigment epithelium and photoreceptors.

Than to buy DRV Black light, try this one - https://ru.aliexpress.com/store/product/Ult...0612.0.0.AoC0lb
It also has the right to exist and radiation harder than that of Black light, something like the "children's version" of a pricked DRL.
She won't lose the Gena for sure, but I can't guarantee the rest......

We use this lamp constantly, sometimes it works no worse than the DRL-250 (sometimes!!!) sometimes there are many flights and interesting species that do not fly on the AWL:

China also offers the following:

Do Vesenitsy fly to the light or not?

ENO, this is all theory, but I'm interested in practical experience. In the diodes, I don't see if there is a generator, and the question was about a specific type of product.

I am well acquainted with various uv housekeepers, and I started with them in the pre-car-generator period. They catch very well-I agree, often those species that ignore the DRL. It was based on the experience of their use that I suggested that a lamp with a similar light, but more powerful (DRL or DRV Blacklight) can in some cases be more effective than a conventional DRL, for example, on a moonlit night and at the same time safer than a beater.

I apologize if I missed the topic.
Do Vesenitsy fly to the light or not?

No, they are daytime, although the cases are different sometimes and not so arrives.

I am writing here about my another attempt to catch on the LED strip. It was on March 28, 2017, but this time not in the steppe, but in the floodplains of the Dnieper near the village of Korsunka. The day was quite warm, the temperature at 5 pm in the region of 20 degrees. The sky was both cloudless and moonless. I don't have a frame for the screen yet, so I fixed it on the bike (although, as I see it, people here fly to the screen, just laid out on the ground. The screen is just needed so that butterflies land on it and they can be clearly seen on it, right?). The ribbon is wrapped around a plastic bucket of condensed milk or dessert.

I turned on the tape at about 19:06, when the sun was setting, and waited until 20: 40. Alas, the result for butterflies is zero. A couple of times, as it seemed to me, some small butterfly calmly flew around the ribbon and did not even think to sit down anywhere (or maybe it was not a butterfly). And I don't understand what they want?

The light shone from the sunset, as Gornostaev's article says. The LED strip is cold white, two meters long, 1 meter at 14.4 W, a total of 28.8 W is obtained - quite a lot. There was a small clearing to the right, and a lot of open space to the left. Among the plants there are poplars, mulberries, willows, willows, rose hips, all kinds of mint, lemon balm, reeds, cattails, reeds, clovers and other meadow and wetland vegetation, and a little further from this area-vegetation of dry sands. But the fact remains that the screen was empty except for a few midges. And a frog came hopping in at half past eight (a croaker, as Hierophis suggested).

A few photos from the test site:

- So. I often just put the screen on the ground.
- According to my observations, immediately after sunset, butterflies fly in autumn. And in the spring they fly when it gets well dark.
- A good result occurs when the weather changes from cold and windy to calm and warm. With stable warm weather, the summer is weak, with cold weather, there is no summer at all. In addition, when the sky is clear, the nights are colder and correspondingly cold. years weak. And yet, according to my observations, in the Crimea, in the steppe, the summer more or less begins somewhere in May, and in March it flies well only in the forest zone.
Thus, the reasons could be as follows: clear sky, cold night, unsuitable for March biotope.

By that time, even we had a lot of nocturnal lepidoptera flying out at much lower temperatures, and it was in the steppe. Although I don't know how they do with phototaxis, I didn't shine, but I looked out for sleeping people during the day. But Vaughn Djon has already caught up to a fig or more on Khortytsia, so it's clearly not about the time of year. Whether you are shining in the wrong place, or in the wrong place.

Dear forumchane, please explain.
In many places I have seen references to egg cells in light traps. What they are for is clear. It is not clear how to then extract the catch from there

Roman, I don't understand the question. Egg trays or their sections for 10-15 pcs. are placed under the screens and the butterflies in them find shelter and stay. otherwise, they would have flown away. You pick it up, look at what's hidden, and if necessary, shake it off in the stain. Especially effective if you are not constantly standing at the screen. they hide and stay there.
Did I answer?

Please advise lamps suitable for light fishing and powered by a 12 V battery.

Alexander, it is clear that they are hiding, it is clear that you are shaking it off, it is not clear how to do this in practice...
we simulate the situation:I have a tray for 10 eggs under the screen, I check it and see two butterflies at different ends of it, I need both butterflies.
the question is how to make sure that both are in the stain.
the tray is uneven and it is difficult to pick out the butterfly carefully, and if it passes with one, then the second, third,.... just from these movements they will wake up and hurry to get out, whether at night or in the morning. as it seems to me. or am I wrong?

I used this method all last year, very successfully, Vasily Sergienko "svm" recommended it to me. Very effective. The butterflies are very tight there. you turn over the trays, they're all sitting like cute things, I looked back and put them down. some of them sit in trays all night, turning them over twenty times. there are many more butterflies lingering in the trays than on the screen. And remove from the tray is not a problem, try it, the questions will be solved by themselves

I'll try

Please advise lamps suitable for light fishing and powered by a 12 V battery.

Something like this. It uses a standard 8 W fluorescent tube. If desired, it can be replaced with a UV tube of the following type: such.

Please advise lamps suitable for light fishing and powered by a 12 V battery.

The simplest option - a piece of diode tape is wound on any suitable cylindrical frame, for example, on a piece of plastic pipe. The length of the tape depends on the capacity of the acc.
If the battery is leaded, you also need a discharge indicator to avoid over-discharging the battery.
I used such a kit - acc. from the uninterruptible power supply 7 A / h + 1.2 m of tape + a homemade indicator with an audible alarm.

Please advise lamps suitable for light fishing and powered by a 12 V battery.

Zhenya, I'm sorry you're tired of diaries . Decided to switch to night mode?

Please advise lamps suitable for light fishing and powered by a 12 V battery.

And I would recommend a housekeeper for 28-38 W, 6000k, I can give you a converter)

Diodes seem to be more economical, and the "housekeeper" loses half the light somewhere inside its squiggles. Only in the kit you must have UV diodes, you can buy them on the radio market or through an intern. Yesterday I watched the first arrival of a shovel on the window in the season (the 75 W incandescent light bulb of Ilyich is on in the room). View of HZ, the balcony has not yet been printed and, accordingly, I have only seen the underside.

In my humble experience, almost zero years on the housekeeper, I tried to shine a 55W lamp, 6500k. But paired with the UV housekeeper delux ebt-01, the result is not bad enough. It is clear that they fly on UV, and the usual housekeeper is just for illumination.

Recently communicated with a colleague who shines a xenon lamp from a car, the reviews are very good.

Gentlemen, I think that Vasily Feoktistov suggested the best option. if there is no car, then in the field from the inverter, the most important thing is a black tube. Of course this is not DRL but infections are flying!

I forgot to add it. I have a 12 v 12 m/a battery that is enough for a black tube + 8 W backlight for 5 hours. Without illumination with its temporary inclusion on 7.

Of course they fly and they do it well
I've been using it in the fields for several years now this installation (3 12-volt lamps of 9 watts each + such a lantern, in which there are two UV tubes of 8 watts each).
Here here its 12-volt part is described in detail.
All this business + the necessary equipment for collecting is placed in an average backpack. I got into the el-ku and drove, and quickly put it in place
But for some reason I don't fly anything on the LEDs, for the life of me (I tried)

Vasily, I lived near you, a black tube as you wrote is fine if there is no car. Ladies and gentlemen, today is a holiday, let's meet in the church!

Happy holiday
I ran this case actually not in the vicinity of the city of Zheleznodorozhny, but much further along our railway: in the vicinity of Omutische Square (der. Starye Omutischi), which is under the Cockerels. Oh and I love those places
And in the vicinity of Fryazevo (Esino Square) I often visit: the places there are a lot of fungi, and in entomological terms they are quite promising.
In general: it is very nice to meet fellow countrymen

And katokal in general is better to lure with a brew, the result will be many times more noticeable than with any lamp, even you will not have to wait for the night.

Katokal day is very good to look for in those places where there are ss. ki human. I have one place in my city: a convenience store that sells beer. And accordingly, the nook behind it, where all fans of this drink release their bladder So: in 2011, C. nupta, C. fulminea, C. sponsa, C. promissa were collected there en masse. In my opinion, these species should be caught in such places, and not try to lure them to the light

Very specific... hmm... I don't think many people have such a biotope at hand. A brew works in any forest. Catocals fly to it in dozens right after sunset, when you can still see everything without a flashlight.

And what in my case is not a brew? The real "brew" itself is. Just about the genus Catocala it is not necessary to say that representatives of this genus fly to the light They, in addition to light, fly to much more....

- So. I often just put the screen on the ground.
- According to my observations, immediately after sunset, butterflies fly in autumn. And in the spring they fly when it gets well dark.

Yes, the sky was clear, but without a moon, starry. So, it's better that there are clouds. The weather during the day was very windy. There, in the lowlands, the wind was very light, but as soon as the Sun went down, I personally felt cold immediately. But is it objective to judge the cold by human feelings? By the way, when I got home, and this is somewhere at 22: 20, it was 12 degrees. Perhaps there, in the plavni, the temperature is lower, because it is still a lowland.

Although I don't know how they do with phototaxis, I didn't shine, but I looked out for sleeping people during the day. But Vaughn Djon has already caught up to a fig or more on Khortytsia, so it's clearly not about the time of year. Whether you are shining in the wrong place, or in the wrong place.

Not so, or rather so, but not only. The screen is needed first of all to increase the area of the light spot, and only then everything else. And the tree frog is a noble one, many people are looking for it all their lives, but they can't find it.

Djon'a on Khortytsia, as I understand it, has oaks, and the oak is the most eaten by butterfly plants (it has the most species). But there are also quite a few species on poplars and willows (in second and third places after oak).

Last night, when the first dustpan of the season landed on my window, there was a full moon, plus a bunch of burning windows in the house, plus a bunch of several powerful grenades in the lanterns very close by. IMHO when there are years, the results will be in any weather, except for severe cold and rain. According to my observations, it flies most closely at the moment when a long period of non-flying weather (at least a week) abruptly changes to flight weather.
