摘　　要：金绿宽盾蝽Poecilocoris lewisi Distant在北京1年1代,以5龄若虫在侧柏(Platycladus orientalis Franco)附近的落叶和石块下越冬,翌年4月上中旬陆续从越冬处爬出,取食侧柏嫩叶。5月中旬5龄若虫开始羽化,6月初为羽化高峰期,6月中下旬羽化期结束,5月到8月为成虫期,7月底到8月中旬交配产卵,8、9月份若虫由1龄发育至5龄,9月中下旬为5龄若虫高峰期,11月5龄若虫开始转移越冬。Based on the field observation and lab rearing, the bionomics of the stink bug, Poecilocoris lewisi Distant, was studied in Beijing. P. lewisi is univoltine in Beijing. The matured （5th） nymphs overwintered in the defoliation and under the stone near Platycladus orientalis Franco in November. The matured nymphs dispersed from overwintering sites in early April of next year and fed on fresh leaves of P. orientalis. Adults emerged in mid to late May and didn＇t lay eggs until late June. Nymphs developed from 1st to 5th instars in August to September. In late September, the matured （5th） nymphs achieve the peak.
