Yes, this is Trigonotylus. The genus is very difficult to determine, it is reliable only from the genitals of males.

15.12.2020 8:22, kovyl

I knew it! smile.gif Of course, I also did the drug. It turned out that this is caelestialium. At first, the fold of the aedeagus membrane was mistaken for a spicule, but after staining (and only membranes are well colored with this dye), I realized that it was not there.
And another question: how do you distinguish between females?
Thanks!

15.12.2020 23:37, Triplaxxx

Well, Trigonotylus caelestialium is probably the most common species of the genus. And as far as I know, there are no females, unless they are collected during mating.

16.12.2020 8:55, kovyl

Of course, it is the most common. But since I have never dealt with bedbugs before, it is not so easy to identify even ordinary species. And to check for all the signs, I make preparations.
And if the females were gathered directly together with the males (mowing)? I think they can be considered a single species? Especially since it was collected on the field. It is unlikely that there is a great variety. And there were no males of other species of this genus.
By the way, I had a similar question about E. integriceps - how to reliably distinguish between females? (the males were perfectly determined by the drug).
And in general, I don't really like the drawings in the green volume, they are very sketchy...

16.12.2020 23:38, Triplaxxx

Well, if the females were collected together with the males, then with a high degree of probability they can be considered one species (in most cases). By the way, this trick with Nabis does not work, it is necessary to dissect everyone.

What is E. integriceps? Eurygaster integriceps? If so, then to identify the species of this genus, you do not need to dissect them, they are already well distinguished.

17.12.2020 8:41, kovyl

Yes, Eurygaster integriceps. They probably differ well, but since I just started dealing with bedbugs, I decided to play it safe.
As for the drugs, there is still a question. Here, as I understand it, is Eurydema ornata and its preparation. Probably a bad angle? Just trying to match it with the one given in the determinant (green volume) and somehow not very similar.

The green determinant shows a view of the external part of the male pygophore and the external parts of the female sexual structures (ovipositor valves, etc.). To view all this, most often you do not need to dissect anything. These signs are often used to identify bedbugs.

18.12.2020 7:53, kovyl

1 -- probably Adelphocoris sp., too poor photo quality and poor angle;
2 -- yes, Oncocephalus pilicornis Reuter, 1882;
3, 4 -- yes, Rhyparochromus vulgaris (Schilling, 1829);
5 -- Beosus quadripunctatus (Muller, 1766);
6 -- the photo is rather weak, but judging by the whiskers, Scolopostethus affinis (Schilling, 1829) .

Yes, this is Megacoelum, but I will not say the type: their color is variable, and the pubescence is not really visible.

Yes, it is difficult to say anything definitely from such a photo - you can't see any antennae, no dotted lines, and the size is unclear. Habitually, it can be assumed that this may be an Orius sp. (reliable only on the male genitals), or, alternatively, Lyctocoris campestris (Fabricius, 1794).

18.01.2021 14:13, kovyl

Unfortunately, it was not possible to capture the dotted line. Size-2 mm.

If the middle and hind legs are dark, it is almost certainly Orius niger (Wolff, 1811), male.

Well, yes, the shape of the parameter within the scope of variability.

Regarding the photo:
1 -- Nabis sp., if it is a male, it is necessary to straighten and examine the paramers, and if the female-to prepare the vagina;
2 -- unfortunately, the dotted line is not normally visible, if the scutellum is not dotted-Deraeocoris lutescens (Schilling, 1836), and if it is dotted, most likely Deraeocoris serenus (Douglas & Scott, 1868) .
