What does the First sting do to the roach?
The first sting in the thorax causes a transient front leg paralysis lasting a few minutes. This paralysis prevents the cockroach from fighting with its front legs, thereby facilitating the second sting in the head. A postsynaptic block of central synaptic transmission mediates this leg paralysis.
What strategies does the American cockroach use to protect itself from the emerald jewel wasp?
In general, the cockroach pushed the leg against the wasp, securely lodging the spines against the wasp’s body and legs, and then simultaneously turned while moving its leg caudally.

Do wasps lay eggs in roaches?
The jewel wasp enslaves cockroaches, stinging their brains in ridiculously precise spots and injecting mind-controlling venom. The wasp then leads its zombified roach to a chamber, where it lays a single egg on its perfectly relaxed host and seals it inside with pebbles.
Do wasps lay eggs in cockroaches?
