When they are injected together in a ratio of Several other species of the genus Ampulex show a similar behavior of preying on cockroaches.

As a result of this sting, the roach will first groom extensively, and then become sluggish and fail to show normal ampulwx responses. Williams in as a method of biocontrol. Wikispecies has information related to Ampulex compressa. It is known for its unusual reproductive behaviorwhich involves stinging a cockroach and using it as a host for its larvae.

The metabolic change is thought to preserve nutrients for the wasp larva. Eventually, the fully grown wasp emerges from the roach’s body to begin its adult comressa. The biochemical basis of this transient paralysis amlulex discussed in a paper.

Not Exactly Rocket Science News. A study [3] using radioactive labeling demonstrated that the wasp stings precisely into specific ganglia of the roach. The wasp actively searches for the SEG during this sting.

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 first sting is delivered to the prothoracic ganglion mass of nerve tissue which causes a 2— to 3-minute paralysis of the front legs.

The wasp, which is too small to carry the roach, then leads the victim to the wasp’s burrowby pulling one of the roach’s antennae in a manner similar to a leash.

The wasp proceeds to chew off half of each of the roach’s antennae. 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. Researchers have simulated this zombie state by injecting procaine into the SEG. They compresa determined using extracellular bipolar electrodes that neuronal activity was less in stung cockroaches.

Taurine and beta-alanine likely extend the duration of the paralytic effect by slowing the uptake of GABA by the synaptic cleft. The flying wasps are more abundant in the warm seasons of the year. The wasp has a metallic blue-green body, with the thighs of the second and third pair of legs red. This has been unsuccessful because of the 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. 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. Basically, it limits the effectiveness of octopamine, the neurotransmitter that controls muscle contraction in sudden movements.
