Estigmena chinensis Hope (Coleoptera: Chrysomelidae) has been recorded damaging green standing bamboos in natural stands and plantations. The borer damage is frequent in solid bamboos of small dimensions and solid parts or thick walls of large hollow bamboos. The effect of temperature and relative humidity on the development of eggs and survival of adults was studied in the laboratory. Results revealed that the population of bamboo borer E. chinensis is greatly affected by the variations in temperature and relative humidity. At 30°C temperature and 70% relative humidity mean longevity of males and females was 11.5±0.23 and 13.5±0.20 days respectively. The study also concluded that the development of eggs was most favorable at 30°C temperature and 70% relative humidity.
