Bibliometric and Visual Analysis of Planthopper Research between 1980 and 2017

Planthoppers are highly destructive pests of rice.We carried out a bibliometric analysis of planthopper research from 1980 to 2017, to retrospect planthopper research progress in recent decades.We found that China leads planthopper research, and that the possible research frontiers are rice resistance or defence to planthoppers, mechanisms controlling planthopper winged morphs, resistance mechanism of planthopper to insecticide imidacloprid, Southern rice black-streaked dwarf virus vectored by planthopper, and molecular and genetic methods in planthopper research (dsRNA, RNAi and genomics).
