French scientists have discovered for the first time in insects, namely in the pea aphid, the ability to use solar energy to generate light in the same way as do the plants during fotosinteza.Gruppa with the head of Alain Robishonom, Agrobiotehnologicheskmy Institute in Sophia-Antipolis, discovered in 2010 else aphid capable of producing carotenoids, i.e. pigments that are essential for different zhivotnyh.Ot these substances depends, in particular, the immune system and production of multi-vitamins. They can be produced by fungi, bacteria, plants, but in animals aphid was the only species that has this ability - the rest are all prepared food these veschestva.Robishon colleagues tried to find out why it took the pea aphid produce carotenoids. Aphids can change color, depending on the vernal conditions. Provided cold offspring of aphids turns green when the temperature returns to the very best - about 22 degrees - are beginning to prevail in the colony orange and yellow individuals in the same lack of resources - even belye.Uchenye measured the concentration of ATP (adenosine triphosphate) - the energy "currency "living organisms, and found that the green aphid, which was recorded the highest concentration of carotenoids produced a lot of ATP. In addition, it was found that the insects to produce more light than in the dark ATP. "This is akin to the work of photosynthetic archaic system" - the scientists say. Though, note that additional experiments to confirm that this is still photosynthesis, and the data support this possibility.
Robishon colleagues believed that insects, photosynthesis is used as an energy source with a shortage of resources, and to survive the migration from one plant to another.
