Seasonal occurrence of microsporidia in moths of the lawn grass cutworm, Spodoptera depravata, was investigated from May to October in 1984. Moths were collected by light traps at Sayama, Chigasaki, and Sagamihara in the Kanto district. The percentage of infected moths increased as the season advanced i.e. from 9.2% in spring to 14.5% in the autumn generation, while the spore density of microsporidia per adult decreased as the generations advanced. The spore size of the microsporidia isolated in the present investigation ranged from 3.37 to 4.46μm by 1.85 to 2.50μm. Of seven stocks selected from these microsporidia, three stocks were infectious to the silkworm, Bombyx mori, and two of the above three induced a systemic infection similar to that of Nosema bombycis.
