The whitebacked planthopper Sogate/la furcifera (Horvath) (Homoptera: Delphacidae) (WBPH) is a serious insect pest on rice whole Vietnam. However, the knowledge of development biology of the WBPH on different rice varieties is still limited. The objectives of this study were to determine some biological characteristics of WBPH in different temperatures. The results indicated that life cycle of the WBPH reared at 25°C was 28,3 days longer than that at 30°C (24.5 days). Longevity and fecundity of the adults at 25°C were higher than those at 30°C. As results, the WBPH is better development at 25°C than at 30°C. These data are important for prediction of WBPH development in the field.
