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."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
