Ampulex sinensis SaussureChlorampulex striolata Saussure, Sphex compressus Fabricius, This has been unsuccessful because of akpulex territorial tendencies of the wasp, and the small scale on which they hunt. It also causes excessive grooming and alterations in the metabolism of the cockroach.
Wikispecies has information related to Ampulex compressa. Over a period of 8 days, the wasp larva consumes the roach’s internal organs in an order which maximizes the likelihood that the roach will stay alive, at least until the larva enters the pupal stage and forms a cocoon inside the roach’s body.
The second sting is administered to the subesophageal ganglion SEG and is much more precise, hence the need for paralysis and is significantly longer. Retrieved from ” https: Views Read Edit View history. The emerald cockroach wasp or jewel wasp Ampulex compressa is a solitary wasp of the family Ampulicidae. Retrieved 7 December With its escape reflex disabled, the stung roach simply rests in the ampuelx as the wasp’s egg hatches after about 3 days.
When they are injected together in a ratio of Development is faster in the compdessa season.
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. The concoction temporarily blocks the motor action potentials in the prothoracic ganglion by depressing cholinergic transmission through the increased chloride conductance across nerve synapses. It then exits and proceeds to fill in the burrow entrance with pebbles, more compresxa keep other predators out than to keep the roach in.
The wasp actively searches for the SEG during ajpulex sting.

Mating takes about a minute, and only one mating is necessary for a female wasp to successfully parasitize several dozen roaches.

The second sting inhibits the cockroach’s ability to walk spontaneously, or of its own will, but cockroaches can right themselves and swim while under the influence, and when startled, will jump but not run.
