It sounds like the start of some Syfy Channel original movie, but scientists are preparing to win the war on agricultural pests by using voodoo wasps that can turn other insects into living hosts for their offspring. Zombieinsectwar go!
Parasitic wasps attack and kill pest insects, but many people don't even notice them or know of their important role in keeping pest numbers down. We owe them a lot. If it weren't for parasitoids and other natural enemies, we would be knee-deep in pest insects... If we can harness their full potential, they would be vastly preferable to chemical pesticides which broadly kill or poison many organisms in the environment.
This isn't the first use of parasitic wasps to help crop production; they were unleashed in California last year to save olive groves from fruit flies.
