Abstract
Field experiments during 2 consecutive rice crops showed the relative abundance of common rice leafhopper and planthopper species as Nephotettix spp. > Sogatella furcifera (Horvath) > Nilaparvata lugens (Stal) > inazuma dorsalis (Motschulsky). The Nephotettix spp. and S. furcifera were more abundant during the early stages of plant growth, while I. dorsalis and N. lugens tended to be more numerous toward crop maturity. All diazinon-treated plots had significantly lower leafhopper and plamhopper populations and low tungro virus infection in comparison with untreated plots. This virus disease is transmitted by Nephotettix impicticeps (Ishihara) and is nonpersistant in the vector. The proximity of virus-infected plants and the insect’s ability to alternately infest diseased and healthy plants appeared to be main factors in the spread of this virus.
