Rough transcription; for its reproduction, the wasp injects a cockroach with poison to paralyze it, then stings it in exactly that part of the brain responsible for its flight reflex to make it docile. After knibbling a bit on the cockroach's antennae and enjoying the hemolymph seeping out of the cockrach, the wasp takes the cockroach by its antennae and, even though it is much bigger than the wasp, directs it to its nest like a dog on a leech. In the nest of the cockroach the wasp lays an egg, which soon hatches a larvae that in turn proceeds to eat the cockroach alive while it is still dazed...And this is just the top of the ice berg.
The other day I encountered an example in David Goulson's recent book Silent Earth (https://www.goodreads.com/book/show/56470413-silent-earth) that I did not know yet about; the emerald cockroach wasp (ampulex compressa).
