It then exits and proceeds to fill in the burrow entrance with pebbles, more to keep other predators out than to keep the roach in. Williams in as a method of biocontrol.

Eventually, the fully grown wasp emerges from the roach’s body to begin its adult life. It delivers an initial sting to a thoracic ganglion and injects venom to mildly and reversibly paralyze the front legs of its victim. Journal of Comparative Physiology.

Ampulex compressa Fabricius The biochemical basis of this transient paralysis is discussed in a paper. The second sting is administered to the subesophageal ganglion SEG and is much more precise, hence the need for paralysis and is significantly longer.

The wasp actively searches for the SEG during this sting. Retrieved 7 December Not Exactly Rocket Science News. Archives of Insect Biochemistry and Physiology. Views Read Edit View history.

While a stung roach exhibits drastically reduced survival instincts such as swimming, or avoiding pain for about 72 hours, motor abilities such as flight or flipping over are unimpaired.

Adults live for several months. The concoction temporarily blocks the motor action potentials in the prothoracic ganglion by depressing cholinergic transmission through the increased chloride conductance across nerve synapses. In other projects Wikimedia Commons Wikispecies.
