I'm not trapping though do keep a watch on hive fronts and this time of year forage sources like fruit and ivy.

how many, on finding velutina in their traps would kill them and then call the AH team?
Don't have much in the way of options really. It is illegal to catch and release AH (so if one ends up in your trap you have to leave it there).
Current protocol is to report with photo then put the whole trap in the freezer.

The lads have come up with the goods again
Nest found!
How do they track a hornet back to its nest? I’ve tried watching an individual bee from a hive on its flight and I soon loose it against the sky or vegetation.

Have a look at the jersey Asian Hornet group on Facebook. There is an endless parade of nests destroyed but somewhere in there is their method. Fascinating. AH don’t forage far from their nests which helps.

I read they actually trap and tag individual hornets in Jersey then release them.

I certainly am.
Me as well ... it would be good to have a defined plan that all beekeepers could follow ... I don't know now just what is best. Indeed - not just beekeepers - it's entirely possible that Joe Public down here may have been putting traps out ?

Triangulation usually. You don't need the complete flight path, just the general direction.
Set out a bait station in location of original sighting and monitor.
Note the direction the hornet flies off from here and mark flight line on map.
Then add bait stations at compass points either side of this direction and record flight paths from each station.
Eventually your map will have a number of marked flight lines which will converge at the location of the nest.
AH generally forages within 700m of the nest so search areas can be defined accordingly.

Telemetry is useful but is now generally reserved for research tracking purposes as it can be expensive/haphazard.
Hornets chew off the transmitters when they return to the nest so new ones need applying.
Also transmitters fall off. Many reports of AH nest tracked to a low bush only to find it is a detached transmitter.
Triangulation is cheap and easy.

Thank you for the explanation.

This being Asian Hornet Awareness Week, is very timely if anyone has a bit of time and would like to volunteer help with their local AH Teams.
There is a short quiz/exercise here for anybody who wants to check their knowledge about AH. Completion of the quiz and registration gives you extra insurance when out locating nests (separate from BDI ).
The quiz itself is extremely simple (it won't let you proceed until you pick the correct multi-choice answer) but it's still very useful.
Removed a few when I was living in France - one on my land 50m from my hives. Nests always way up in tall trees - which is not even an option on this quiz 🤷🏻
