A researcher at Vanderbilt University may have discovered how American cockroaches can avoid their own "zombie apocalypse."
Ken Catania, a biologist and professor at the school, recorded interactions between the cockroaches on video and their predators ̵
"It's a kind of famous interaction in biology circles and beyond," Catania told Fox News.
An emerald jewel wasp will temporarily paralyze the front legs of an American cockroach and "weave its sting through the cockroach's throat into its brain," essentially "zombified," he explained.

"When the poison becomes effective The cockroach becomes passive and can be channeled through its antenna into a hole where the wasp drops an egg and then sealed the exit with debris, "he wrote in an online study Wednesday in Brain, Behavior and Evolution." "The cockroach has the ability to run, run or fly when properly stimulated, but it tries not escaped as it is slowly being eaten by the developing wasp larva. "
Adult American cockroaches Catania found that they were often" surprised by the wasp "in match matches, in situations where a cockroach surprises and having no time to defend themselves, the survival rate is only about 14 percent.
Catania's study found varying survival rates for interactions between emerald jewel wasps and American cockroaches. In his research, he found that the mistakes can use certain tactics to avoid a cruel fate.
If American cockroaches occupy an enormous position, they can attack their attackers, he explained. The cockroach "will most often hit the wasp over and over again."
Catania said he had heard of the cockroach sniper tactic in passing, but it has not been investigated yet.
"It takes a couple of hits to convince the wasp that there is a simpler cockroach," he said. He said he had hind legs with "really intimidating spikes" and likened them to a "spiked club" that you use for self-defense.

"People often talk about how important it is to be fast when they are prey," he said Catania. "Here's two thousandths of a second difference."
Catania believes his findings could be useful for a variety of reasons.
"It's not only fascinating to understand how the world works and how predator-prey interactions work." however, it could also be useful for educational purposes.
