The invasive Turkestan cockroach is displacing the oriental cockroach in the southwestern US

09.12.2013
The Turkestan cockroach, Blatta lateralis (Walker), has become an important invasive species throughout the southwestern United States and has been reported in the southern United States. It is rapidly replacing the oriental cockroach, Blatta orientalis (L.), in urban areas of the southwestern United States as the most important peri-domestic species.

In 1978, the Turkestan cockroach was first reported at Sharpe Army Depot in Lathrope, CA, and it is now widely distributed throughout California and urban centers of the southwest.

This species is widely available for purchase on the Internet by animal breeders needing live insects. They are especially popular among reptile breeders because they are easily maintained in the lab, unable to climb smooth surfaces, breed in large numbers, and easy to handle.

However, even though Turkestan cockroaches are now widespread and readily available on the Internet, there is little information on their biology. In a new article in the Journal of Economic Entomology called "Life History and Biology of the Invasive Turkestan Cockroach (Dictyoptera: Blattidae)," the authors describe its life history and they compares this information with the closely related oriental cockroach.

Two parameters that might contribute to the success of Turkestan cockroaches compared with oriental cockroaches, the authors write, are that the developmental period of the nymphs of Turkestan cockroaches are shorter, and adult female Turkestan cockroaches produce considerably more eggs than do oriental cockroaches.

They also have a more rapid life cycle than the oriental cockroach, allowing them to become adults after five molts, whereas oriental cockroaches require between 7 and 10 molts.

"It will be interesting to follow the spread of the Turkestan cockroach in the United States," the authors write. "This may be the first time that an invasive urban pest species is widely distributed via the Internet and through the sale of live insects."

Members of the media who would like an advanced copy of the article should write to rlevine@entsoc.org or call 301-731-4535, ext 3009.

The Journal of Economic Entomology is published by the Entomological Society of America, the largest organization in the world serving the professional and scientific needs of entomologists and people in related disciplines. Founded in 1889, ESA today has more than 6,500 members affiliated with educational institutions, health agencies, private industry, and government. Members are researchers, teachers, extension service personnel, administrators, marketing representatives, research technicians, consultants, students, and hobbyists.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
