Tekken
The Hawaii State Legislature is currently discussing legislation ( House Bill 2207 ), which may allow specific types of fish net to be used in protecting plants from damage by coconut rhinoceros beetle adults. This blog post provides technical information relevant to this discussion from my work as an entomologist at the University of Guam.
Background¶
Specifications¶
Modes of use¶
Nontarget bycatch¶
On Guam, I occasionally observed brown treesnakes and lizards entangled in netting. I did not observe insects other than CRB, birds or mammals trapped in the netting. However, it should be noted that populations of small mammals and birds on Guam are at low densities because of brown treesnake predation.
I currently operate a single tekken trap, baited with CRB pheromone, in a forested area in the Philippines where birds and small mammals are abundant. Since the trap was installed on December 25, 2025, only a single CRB and no other animals have been trapped.
