MOSCOW, 6 Jul – RIA Novosti. Insects with large reproductive organs can cope with them during sex due to the unusual nature of their rigidity, said Japanese and German biologists, speaking at a meeting of the community of biologists and experimenters in the British Brighton.

“How this discovery can be useful in practice? We have not yet tried to use it in some other areas, but I believe that understanding how you can control the movement of the tube in a narrow passage can help us to create a harmless catheters or hypodermic needles,” said Yoko Matsumura (Matsumura Yoko) from Keio University in Yokohama (Japan).

Many insects have very long reproductive organs with a very bizarre shape and the device – for example, the length of the penis in males of many species of beetles exceeds the length of the body several times, and their shape often take extremely whimsical forms that mirror the structure of the sexual passages in females. Biologists often think about how the insects manage to control the work of such a complex and large bodies when mating. © A. M. Herrera and M. J.

Matsumura and her colleagues, the Ukrainian-German biologists Alexander Filippov, Alexander Kovalev and Stanislav Gorb from the Donetsk physical-technical Institute and the University of Kiel (Germany), figured out how the insects manage to cope with their exaggerated sexual organs, creating a computer model of a penis bugs insects species Cassida rubiginosa. Scientists have found a clam, puncture the head partner before mating

As shown by their calculations, these beetles can control their penises and not to break them when mating due to the fact that their rigidity differed at the beginning and at the end of the reproductive organ. According to the researchers, the penis Cassida rubiginosa noticeably softer at the tip than at the base, which helps them to pass through a narrow and winding simplemente females, similar to the spiral in its form.

Form and the device of the penis and female genital organs faster and stronger things change in the course of evolution, and their physical properties, as the scientists write, are rarely studied by biologists when studying the process of emergence of new types of insects and other living beings. Therefore, the model of Matsumura and her colleagues, and received data, as I hope the report will help us better understand how and why this happens.
