Both attackers induced strong accumulation of phenolamide phytoalexins in the leaves. In addition, these phenolamides were directly toxic to brown planthoppers when added to artificial diet used for rearing of these insects in the laboratory. Our work proposed a new group of defense compounds in rice that is highly effective against various types of insects.
