Endophytic fungi is an endosymbiont that lives within host plant tissues and does not necessary cause any harm to plants. This type of fungus are important as mediators in plant-herbivore interactions. One of the endophytic fungi in rice is <em>Nigrospora</em> sp. The effects of <em>Nigrospora</em> sp. on the biology and demographic statistic of <em>Nilaparvata lugens</em> Stál (Hemiptera: Delphacidae) were studied in the laboratory. We used<em> Nigrospora</em> sp. culture powder was used to inoculate the fungi to rice seeds by mixing 10 g of flour endophytic per 1 kg rice seeds. The mixture was then stored in damp and dark storage. Results showed that the rice seeds treated with endophytic fungi showed some resistance to<em> N. lugens</em>. Eggs and early stages of nymph mortality was increased, higher than the control. Endophytic fungi also affect the nymphs growth rates by slowing it down, prolonging <em>N. lugens</em> life cycle, preoviposition period as well as delayed the age at first reproduction. <em>N. lugens</em> population growth is effected by <em>Nigrospor</em>a sp. in laboratory scale. Thus, it has the potential as an alternative way to control <em>N. lugens</em> population. In addition, inoculation of endophytic fungi could be a useful method for protecting rice plants from <em>N. lugens</em>.
