the genus Periplaneta) can be found. Researchers[7] using radioactive labeling demonstrated that the wasp stings precisely into specific ganglia of the roach. It then exits and proceeds to fill in the burrow entrance with any surrounding debris, more to keep other predators and competitors out than to keep the roach in. Distribution 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. [5], The wasp has a metallic blue-green body, with the thighs of the second and third pair of legs red. The wasp actively searches for the SEG during this sting. When several references are cited, they may give conflicting information on the status. Web. The specimens collected were prepared, identified, labelled and added to the biological collection located in the “Acervo Biológico da Amazônia Meridional” of the Universidade Federal de Mato Grosso, in Sinop, Mato Grosso. [9] The venom is reported to block receptors for the neurotransmitter octopamine.[10]. This insect presents a metallic body colour pattern, usually in blue or green, and this colouring is responsible for A. compressa being popularly known as “jewel wasp” or “emerald wasp.”. and YUSTIZ, E., 1983. When they are injected together in a ratio of 10:7:4, the effect was longer lasting. Title. Synonym. Williams in 1941 as a method of biocontrol. Basically, it limits the effectiveness of octopamine, the neurotransmitter that controls muscle contraction in sudden movements.[13][14].

In the burrow, the wasp will lay one or two white eggs, about 2 mm long, between the roach's legs[3]. A. compressa was introduced to Hawaii by F.X. [ Links ], BUYS, SC., 2007. Over a period of 8 days, the final-instar larva will consume the roach's internal organs, finally killing its host, and enters the pupal stage inside a cocoon in the roach's body. With its escape reflex disabled, the stung roach simply rests in the burrow as the wasp's egg hatches after about 3 days.

As a result of this sting, the roach will first groom extensively, and then become sluggish and fail to show normal escape responses. Most of the >130 species occur in the tropics, particularly in the Old World, and fewer than 15 are known from the New World; fewer than 5 species are native to Europe or the United States, though the Old World species Ampulex compressa has spread to virtually everywhere that its host roaches (esp. The flying wasps are more abundant in the warm seasons of the year. [2][3] The wasp, which is too small to carry the roach, then leads the victim to the wasp's burrow, by pulling one of the roach's antennae in a manner similar to a leash. It thus belongs to the entomophagous parasites. Link to the Code of Intellectual Property (Legifrance). EOL has data for 3 attributes , including: geographic distribution includes Synonym. A total of 23 wasps were reared, which attacked about 80 cockroach hosts. ... Ampulex sinensis De Saussure, 1867 . Distribution. 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. The wasp is mostly found in the tropical regions of Africa, South Asia, Southeast Asia, and the Pacific islands. Introduction to Ampulex compressa: scientific and common names, protected status (red lists, regulations), biological status in France, historical and contemporary.
