The researchers from INRA say it's bullshit, but hey, business is businessContrary to popular belief, the focus on entrapment of foundresses does not provide real solutions in the fight against the expansion and predation of the yellow-legged hornet.
As I understand the principle, all the insects that come in through the cone and can come out through the holes in the grate are safe. So the big insects that go there are eaten by the hornets, as well as the bees not fast enough. It's free massacre.
The quantity in the cagot is substantial. After that we will say that the insects disappear.
Any trap captures indiscriminately ... whether it's this sophisticated trick or a spilled bottle with jam and honey at the bottom or a blue lamp for other insects.
In a sense it's silly it reminds the so-called nets fishermen supposed to sort
This does not detract from the problems posed by Asian hornets against bees.
It seems to me that more interesting solutions exist but I'm too lazy to look ...
