In double cropping fields, there has been a risk of increase rice stripe viral disease outbreaking as the vector, small brown planthopper that overwinter in barley fields increases. Especially rice cultivation in Honam region has two types of cropping system such as rice only cropping in a season and double cropping both of rice and barley. In double cropping system, harvesting of barley could induce migration of the vector from barley to rice field. We found that the vector's density was different in rice fields by distance from barley field. The vector's density in rice field was highest 63 numbers within one meter from the neighbor barley field, and the numbers reduced greatly as the distance from barley field increases. The disease incidence according to rice cultivation methods was different, Donjin 1 was appeared to be a susceptible variety showing 2.4% and 2.5% of disease incidence in direct and transplanting cultivation, respectively. The small brown planthopper in a nearby rice field reach peak 3 days after the barley field was harvested.
