Khmer farmers are awaiting the import of Apoanagyrus Lopezi, a parasitic wasp that will help farmers alleviate mealybugs infestation, from Thailand.
Thai farmers have already use the wasp as a natural pest control. It's much cheaper and overall healthier than pesticides, but could become an invasive species like the cane toads of Australia.
If you've ever seen parasitic wasp, it's like something from the Alien movies. The will lay their eggs in a host. When the egg hatch it will eat away at the host until it matures.
