英文摘要： The life history and habits of Corythucha ciliata (Say) was observed in Shanghai, and its occurrence was investigated. There were five generations each year and overwintering adults could survive on trunks and branches in middle and late October in Shanghai. Adults began to damage in middle April and laid eggs at the end of April. The nymphae of first generation was found at the beginning of May, which duration was 17 to 18 d, and the whole generation duration was about 30 d.
