Are there any publications or unpublished data on pheromones available for Boris schneideri (Insecta: Coleoptera)?
Let me know if you find anything! That's on my list as a potential next rare new for Britain species in the Caledonian Pine Forests!
I don't think one has been identified yet, although it would be a good indicator species of course. A good place to check is http://pherobase.net/database/family/family-Tenebrionidae.php
Hi Dmitry, I have never read or heard about pheromones of B. schneideri.
Ditto Max - I'm not aware of anything, but would try it on our B. unicolor here in the colonies!
Boros is rather common in Latvia. Any chance to identify the pheromone if I will be able provide alive material?
Max, just visit us to see the habitat. This species is very easy to find and recognize its larvae
The same is true of our (North America) Boros unicolor in many places. However, as easy as it is to find larvae, adults are generally quite uncommon in collections. Larvae of B. unicolor are typically found beneath bark of dead Pinus spp. (mostly standing); most commonly breast-high and lower.
Potentially we could do some preliminary GC/MS analysis on the pheromone if someone were to provide us with living specimens. The import regulations might be a bit restricitve in the UK for this though. We could also get others to send us a gland extract stored in solvent to have a look at. I don't know much about tenebrionid pheromone glands, do you think they are abdominally secreted?
Imago or larvae - this is the question. Larvae are no problem to find and ship to UK. But imago are some kind of short-living (not sure they will survive 3 weeks in post).
Anthicidae (also tenebrionoid beetles) bear mesothoracial glands. So perhaps this is true for Boridae as well.
If they can be reared from larvae and will emerge sucessfully then that is ideal. I don't know about how difficult they would be to rear?
According to my personal experience they are rather easy to rear. I will ask my colleagues about imago first - perhaps somebody can provide imago and I will add larvae.
I have about 20 larvae (various ages) and 4 imago specimens of Boros schneideri. I need an address to ship them (at Monday).
Dmitry
Ooh! Dmitry, if you find any information, it will be interesting for me too. Regards.
Vladyslav, Boros scheideri is rather easy to collect in Latvia and W Russia. Perhaps the situation in Ukraine is same. If you know the microhabitat - this species is everywhere!
I do not know about all Ukraine situation, but in the Carpathians it's the very rare species.
I am rather sure this species is everywhere where there are pine forests. At least in N Europe
Yes, I understand. But in the Carpathians a pine is almost no. That because I wanted to know about effective pheromone and try to find in spruce forests.
O! I set traps in an oak forest just a few days ago. May be it will lucky)))
