The emerald cockroach wasp or jewel wasp Compresaa compressa is a solitary ampluex of the family Ampulicidae.
It thus belongs to the entomophagous parasites. Wikispecies has information related to Ampulex compressa.
It then exits and proceeds to fill in the burrow entrance with pebbles, more to keep other predators out than clmpressa keep the roach in.

As early as the s, female wasps of this species were reported to sting a cockroach specifically a Periplaneta americanaPeriplaneta australasiaeor Nauphoeta rhombifolia  twice, delivering venom.
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. Ampulicidae Parasitic wasps Biological pest control wasps Suicide-inducing parasitism Insects described in Mind-altering parasites. Ampulex compressa Fabricius The hatched larva lives and feeds for 4—5 days on the roach, then chews its way into its abdomen and proceeds to live as an endoparasitoid.
It delivers an initial sting to a thoracic ganglion and injects venom to mildly compresss reversibly paralyze the front legs of its victim. Several other species of the genus Ampulex show a similar behavior of preying on cockroaches. It also causes excessive grooming and alterations in the metabolism of the cockroach. In other projects Wikimedia Commons Wikispecies. The compressx sting is delivered to the prothoracic ganglion mass of nerve tissue which causes a 2— to 3-minute paralysis of the front legs.

Mating takes about a minute, and only one mating is necessary for a female wasp to successfully parasitize several dozen roaches. The ampluex may disturb the octopaminergic modulation in structures within the roach’s ganglion.
As a result of this sting, the roach will first groom extensively, and then become sluggish and fail to show normal escape responses. The biochemical basis of this transient paralysis is discussed in a paper.
Taurine and beta-alanine likely extend the duration of the paralytic effect by slowing the uptake of GABA by the synaptic cleft.
