Bug fight: the emerald ash borer vs. parasitic wasps

“It's a tiny wasp, you know, the tip of a pin size. And it comes along, finds an emerald ash borer egg and lays its egg inside that egg. And then it hatches and emerges as a wasp. What we say is, if you've ever seen the movie Alien, where the thing comes bursting out of the dude's chest…that's how parasitoids work.” ― Chris MacQuarrie, Research scientist for the Canadian Forest Service at Natural Resources Canada Since its arrival in North America in 2002, the emerald ash borer has killed millions of ash trees, with billions more at risk.
