Spotted Lanternflies Outsmart Birds with Pungent Toxin
In a bizarre display of survival tactics, spotted lanternflies have been found to produce a foul-smelling toxin that deters birds from making a meal out of them. According to research from Penn State University, these invasive insects store the bitter compound in their bodies, which is derived from the tree of heaven, their preferred food source.
Studies have shown that when birds are deprived of feeding on sap from the tree of heaven, they are more willing to eat the lanternflies. In fact, researchers found that birds, including nesting house wrens, were less attracted to lanternflies that had fed on the toxic plant compared to those that hadn't.
The toxin, known as quassinoids, was accumulated in the lanternflies' bodies by the insects themselves when they fed on tree of heaven. When researchers tested different life stages of the spotted lanternfly in controlled environments, they found that adults produced higher concentrations of quassinoids after consuming the toxic plant.
To test their theory, researchers also used suet cakes with and without lanternflies that had fed on tree of heaven to gauge the preferences of birds. The results showed that most bird species preferred the lanternflies that hadn't fed on the toxic plant, while house wrens were particularly reluctant to feed their young with them.
The research suggests that this pungent toxin provides the spotted lanternfly with a natural defense against avian predators, giving it an edge in its battle for survival. And it's not just the adults that benefit – the eggs of spotted lanternflies also contain quassinoids, which are inherited by the offspring from their mothers.
As researchers look to find ways to control the spread of these invasive insects, one promising strategy is the introduction of parasitic wasps from China that can safely curb populations without harming native species. With the Philadelphia region likely due for another big wave of spotted lanternflies in the future, this natural approach may be just what's needed to keep their numbers under control.
While the spotted lanternfly infestation has subsided somewhat since its peak during the COVID-19 pandemic, experts warn that it will continue to fluctuate and expand. By studying the behavior of these insects and developing effective strategies for controlling them, researchers hope to bring an end to the devastation they cause in our ecosystems.

spotted lanternflies are literally outsmarting birds with a toxic compound 
i mean what's next? other insects gonna start using mind control on humans too 
and we're still dealing with these invasive species? it's like the world is just one big disaster movie 
.
. It's kinda wild that they can store this quassinoid stuff in their bodies and it repels birds, but at the same time makes them more vulnerable to predators themselves? Like, what's up with that? 
I feel like these little bugs are like the ultimate underdogs - no one wants to mess with 'em because of that yucky smell, but at the same time they're still gonna spread and cause trouble. Can we just get rid of them already?! 
they produce this yucky toxin that repels birds lol what a clever move for an invasive species 
i mean who needs predators when u got ur own built-in defense mechanism 
so yeah researchers are trying to find ways 2 control the population without harming native wildlife 
hope they come up w/ a solution b4 it's too late & our ecosystems r left in ruin 
sounds like parasitic wasps could be a game-changer for us 
And can we talk about how these little guys are like the ultimate ninjas? They store this toxin in their bodies, and then BAM! They're like, "Hey, birds, stay away!" 
i mean who knew they had a toxic trick up their sleeve lol but seriously can we just appreciate how clever these little bugs are? i mean they're like "hey birds, i've got a stinky secret and you're not getting any sap out of me today" 
and it's working too! 
i'm all for finding natural ways to control their population like introducing parasitic wasps from china that's a solid plan imo 
.
. Introducing parasitic wasps from China could be a game-changer in controlling those pesky lanternflies populations 
Who needs a cape when you've got quassinoids?
