• Field and laboratory experiments were conducted to assess the validity of the theoretical model; A_t=1-exp (-α・N_A・L・P), where A_t is the percentage of rice hills infected with rice dwarf virus (RDV), α is the number of hills infected successfully by a vector per day, N_A is the total number of adults per hill that have immigrated, L is the mean longevity of the adults in the rice field and P is the percentage of infective individuals. The calculated value obtained by substituting observed values for the parameters in the model showed close agreement with the observed value for A_t. Management of RDV infection in rice fields based on the relationship between the proportion of infected hills (A_t) and the product of parameters (α・N_A・L・P) is also discussed.
