Aphis codecodesubordo Fulgoromorpha, especially the small ones. Tonggeret was once classified as a wereng (under subordo Auchenorrhyncha) but now has been separated by taxonomy. Due to the exclusive life of the plant, a number of its members become an important pest in the cultivation of plants. In addition to being a direct feeder, the aphis is also a vector for the transmission of a number of important plant diseases, especially from the viral group.

Some books still use the name Auchenorrhyncha to call Fulgoromorpha.

Brown planthopper (Nilaparvata lugens) is one of the most dangerous and harmful rice pests, especially in Southeast Asia and East Asia. These small insects suck the liquid plants and also spread some viruses (especially reovirus) that cause tungro disease).
Javelin beetles eat the planthopper and their children while a number of bees play the role of egg predators. This natural predator can control the population of planthopper below the threshold of the aphis population, especially the growing season with the number of pests slightly, thus preventing the outbreak of the main virus.
