A

Science Daily -------- Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean（地下的）and above ground herbivorous（食草的）insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. Thus, aboveground insects are warned that the plant is already “ occupied”.

                     In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean residents and vice versa（反之亦然）. It seems that a system has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition.

       Through the “green telephone lines”, subterranean insects can also communicate with a third party, namely caterpillars（毛虫）. Parasitic wasps（寄生的黄蜂）lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, The communication between subterranean and aboveground It is still not clear how widespread this phenomenon is.

       This research was carried out at the Netherlands Institute for Ecology by Roxina Soler, Jeffrey Harvey, Martijn Bezemer, Wim van der Putten and Louise Vet. was funded by the Free Competition of NOW Earth and Life Sciences.
