THERE MUST BE A SPECIAL SPOT IN HELL FOR MALTHUS:

Voodoo wasps that could save the world: Genetic breakthrough could enable scientists to unleash armies of insects on deadly crop pests (Steve Connor, 15 January 2010, The Independent)

The wasps are only 1 or 2 millimetres long fully-grown but they have an ability to paralyse and destroy other insects, including many of the most destructive crop pests, by delivering a zombie-inducing venom in their sting.

Now scientists believe they have made the breakthrough that will enable them to recruit vast armies of voodoo wasps to search and destroy farm pests on a scale that could boost crop yields without polluting the wider environment with insecticides.
