The adult fecundity, egg hatchibility and nymph development of N. muiri China and N. bakeri (Muir), two sibling species of Nilaparvata lugens (Stl) were studied on several common gramineous crops or weeds by using the cage method in laboratory. The results indicated that the suitable hosts of N. muiri and N. bakeri were Leersia hexandra Swart and Leersia sayanuka Ohwi which are different from N. lugens whose suitable host was Oryza sativa. Both N. muiri and N. bakeri could complete their life cycle on rice but could not continue to propagate because the population trend indexes were only 0.2 and 0.02, respectively. The fecundity of N. lugens was significantly higher than N. muiri and N. bakeri. The highest population trend indexes of the three Nilaparvata species were 333.82 of N. lugens on rice, 82.06 of N. muiri on L. hexandra and 39.28 of N. bakeri on L. sayanuka, respectively.
