The green rice leafhopper, Nephotettix cincticeps is an insect vector which transmits virus diseases of rice plant causing severe damage to the rice and its damage both quality and yield of rice. Survival rate of overwintering N. cincticeps in Alopeculus acquadis among 15 species of the winter crops and weeds was 37.8% and its most preferred. Density of N. cincticeps in environment-friendly agriculture area which cultivated Astragalus sinicus as a green manure crop in winter season increased in number wintering pass in Alopeculus acquadis and Astragalus sinicus as host plants, because of control of N. cincticeps was not enough in the previous year. Survival rate of N. cincticeps was higher mainly in habitation mixed with rice straw, Astragalus sinicus and Alopeculus acquadis as winter habitation. It warmed due to the effect of the keeping warmth inside of a rice paddy field and the bank around a rice field covered with rice straw or Astragalus sinicus. Also, habitation conditions were optimal for survival because of growing Alopeculus acquadis as the major host plant of N. cincticeps in that place.
