Periplaneta Japonica is the scientific name for a new and hardy cockroach species that’s made its way to NYC, and being naturally resistant to the frigid temperatures in the cold winter months, could pose a real threat. Fortunately, scientists have deemed it very unlikely that these “super roaches” will be able to breed with the cockroaches already in New York City, so their visit should be brief, NewsMax reports this Monday, Dec. 9, 2013.
The Periplaneta Japonica have seemingly invaded NYC, bringing even higher numbers to the troublesome cockroach population, and being resistant to the freezing cold — even being able to live out in the snow-laden temps — have some civilians worried. But experts are reassuring people that mating with the local roaches probably won’t happen.
According to insect biologists, the Periplaneta japonica species has long been recorded in Asia, but only recently have they made their way onto U.S. lands. Fortunately, these entomological gurus feel that the overall impact from these cockroaches entering the country should stay small, but admit that it is too soon to be sure we are threat-free.
"Because this species is very similar to cockroach species that already exist in the urban environment," Evangelista said, "they likely will compete with each other for space and for food."
This stringent competition among local NYC roaches and the super hardy Periplaneta japonica is hoped to keep overall cockroach populations low, especially in urban environments. The reasoning? Adds the source, "because more time and energy spent competing means less time and energy to devote to reproduction."
However, even without the possibility to breed with U.S. roaches, the recent unveiling of the Periplaneta japonica’s presence is still one to keep a sharp eye on. Says one entomologist and professor from Purdue University on these cold-resistant and frigid temperature-bearing bugs:
"To be truly invasive, a bug species has to move in and take over and out-compete a native species," he said. "There's no evidence of that, but that doesn't mean we shouldn't be concerned about it."
