摘　　要：为了明确甘肃省景泰县梨茎蜂的年发生规律和日活动规律,利用黄色诱虫板于2011—2012年采用五点取样调查梨茎蜂的为害情况和生活史。定期取样和诱捕成虫监测表明,梨茎蜂在甘肃景泰一年发生一代,以蛹在被害枝条内越冬,主要为害梨树新梢,品种及树龄不同,新梢受害程度各异。梨树盛花后,连续晴天且上午9:00气温达到21℃,成虫开始出枝为害,成虫出枝期为4~6天。综合上述得出,防治梨茎蜂的关键时期是梨茎蜂成虫发生盛期、成虫出枝期。In order to determine occurrence regulation and of Janus piri in Jingtai, Gansu Province, the damageand life history of J. Piri were investigated by the five point sampling from 2011 to 2012 with yellow trap board.The results of periodical sampling and trapped adults monitoring showed that J. piri occurred one generationevery year and mainly damaged fresh treetop. Pupa overwintered in the damaged branches. Different varietiesand trees at different ages had different damage degrees. The adults began to damage the pear shoots when itwas sunshiny and the temperature was above 21℃ at 9：00 am from the end of April to the beginning of May,and the damage period was 4~6 days. The results indicated that it was the key period for controlling the adultsof J. piri when adults occurred at the peak and got out of the shoots.
