• Effects of temperature and host stages on spore form of Entomophthora sphaerosperma in Nilaparvata lugens were investigated. In each host stage, at the range from 15 to 25℃, the fungus formed more resting spores rather than conidia in proportion to the decrease of temperature. At each temperature, it formed more resting spores rather than conidia in the old nymph than the young one, in the adult than the nymph, in the macropterous than in the brachypterous adult, and in the young macropterous female than the aged macropterous female. The mortality due to this fungus was higher at lower temperature in each stage, and at each temperature it was higher in the old nymph than the young one, in the adult than the nymph, and in the macropterous than the brachypterous adult. This tendency coincided with the tendency of resting spore formation.
