Insects hold thier breath

The scientists have recognized that certain insects, can send their breathing during the hours, even days. A new study shows why: too much air, to kill.
And insects breathe through the holes, called spiracles, in its whole body. Some insects close the holes from time to time. The scientists had thought, perhaps they have arrested to breathe to the loss of water or to adapt to environments with carbon dioxide, but no evidence supports sound idea.
The new study shows that if the oxygen we need is an insect, to tissue damage. The opening and closing of spiracles is in a way that airs carbon dioxide according to the identified needs, without the inhalation of oxygen.
The research was by Stefan HETZ Humboldt University in Berlin and Timothy Bradley of the University of California, Irvine. It is in 3rd February issue of the journal Nature.
Insect package corresponds to the lungs to a large part of her body. Hit the air industry throughout the body - an efficient system to vigorously breathing critters. The introduction of air and carbon dioxide is more than 100 times faster than through the blood, as with the people.
The researchers studied the dolls butterfly atlas moth night and found it manages to keep the oxygen constant.
"Historically, the physiologist, justified the spiracles open during the financial year to deliver more oxygen," Bradley HETZ and write. "We say it openly, because they are free from the need to close."
The scientists provide "evidence" that the insects, their breathing not acquire to oxygen as well as to prevent, said Thorsten Burmester from the Institute of Zoology at the University of Mainz in Germany. Burmester was not involved in the research.
"The hypothesis has serious implications for the way we believe that the breathing of the animals," Burmester wrote in an analysis of monitoring in the magazine
