Coworker says smashing Japanese beetles will attract more? (lemmy.world)

Hello,

I recently had a coworker mention, " You can't just smash Japanese beetles because it will only attract more through a pheromone they release when dying."

Is this actually a thing or is he misremembering some old gossip's tale?

Thanks, DrHugsyMcFur

Wasps can emit alarm pheromones that inform other wasps that it's in trouble. Smashing it can I think also cause this. https://phys.org/news/2015-12-arms-social-wasps-alarm-pheromones.html

Those are colony insects that have a cooperative survival strategy. Japanese beetles don't do that as far as I'm aware.
