A new mechanism of plant protection from pests
Researchers from the Institute of chemical ecology max Planck (MPG ICE) and Swammerdam Institute (SILS) in the Netherlands have discovered a new defense mechanism of plants against pests.
It turned out that the wild tobacco Nicotiana-specific pest are caterpillars of the hawk moth Manduca sexta, are able to select a group of volatile chemicals that attract to the scene of predatory bugs of the genus Geocoris,
Also interesting is the fact that they have been allocated of the substance are not a strong attractant to predators, but stonovyatsya those in contact with the saliva secreted by the caterpillars.
Earlier, a group of scientists from the Institute of chemical ecology max Planck (MPG ICE) has found that substances contained in the saliva initiate hawk and the other security reacii the plant, changing the opening time of flowers, which changes drastically the spectrum of pollinating species.
