Updated Koldo Belaska trap design for honey bee hives

In Spanish field tests, a simple tubular trap positioned at honey bee hive entrances reduced yellow-legged hornet attacks by approximately five times, allowing bees to forage normally while capturing the invasive species and minimizing effects on non-target organisms. The trap, a modified design by Spanish beekeeper Koldo Belaska, consists of a horizontal mesh tube placed at hive entrances, with vertical "chimney" tubes at both ends to trap hornets.
