How to control the number of birds cicadas

Greater rigor cicadas spend part of their lives as larvae, digging holes in the ground. When the time comes, the larvae come to the surface and turn into winged birds chirping. In this case, the biological clock controlling the conversion of cicadas have a rather unusual: the larvae come to light every 13 or 17 years. Such a strange and long cycle life Seen a long time, in the XVII century, but still a satisfactory explanation for this was not. Environmentalists from Cornell University (USA) have put forward an interesting hypothesis, believing that through their life cycle cicadas manage the Read more [...]

Giperparazity overheard SOS-signals plants

Scientists have found that biparasitic riders can "eavesdrop" chemical signals SOS-infected plants, which are the addresses to their helpers - parasitic riders caterpillars. The paper was published in the journal PLoS One. Riders called parasitic wasps that lay their eggs in the caterpillar's body - their larvae eat the larvae of butterflies inside and use their body as a cocoon. Destroying tracks, riders help plants survive - this principle is used in some countries to control pests.It is known that by eating caterpillars, some plants produce specific volatile compounds - SOS-signals, Read more [...]
