science daily (apr. 27, )-- dutch ecologist roxina soler and her colleagues have discovered that subterranean (地下的) and aboveground 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. this way, aboveground insects are warned that the plant is already "occupied".
aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. this messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for, the same plant.
in recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean insects and 'vice versa (反之亦然). it seems that a mechanism (機制) has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. this avoids unnecessary competition.
