Flying in tune: Buzz brings mosquito pairs together

12.07.2006
Human beings are not the only animals keenly attuned to the high-pitched buzzing of mosquitoes--in fact, researchers have discovered, mosquitoes of both sexes are themselves highly responsive to the sounds of other mosquitoes and enter into complex mid-flight pre-mating duets that serve as a means of sex recognition.

The findings are reported in the July 12th issue of Current Biology by Gabriella Gibson of the Natural Resources Institute at the University of Greenwich and Ian Russell of the University of Sussex.

It has been known for decades that the highly specialized hearing organ of male mosquitoes enables them to detect and locate females. In the meantime, the potential for female responsiveness to sound has been overlooked, mainly because their antennae are so much simpler in form. Nonetheless, their auditory sensitivity is among the best of all insects analyzed thus far. Gibson and Russell have now demonstrated that pairs of flying Toxorhynchites brevipalpis respond to each other in a feedback-like interaction, such that each alters its own flight tone in response to the flight tone of the other. This interaction continues until the tones converge, in the case of male-female pairs, or dramatically diverge, in the case of same-sex pairs.

This flight-tone communication effectively serves as a mechanism for bringing together mosquitoes only of opposite sexes during pre-mating encounters and may hold the key to understanding how closely related species recognise con-specifics--that is, members of their own kind--because, the authors suggest, it is unlikely that identical sex-specific flight tones will be shared among different mosquito species.

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.
