摘　　要：马尾松腮扁叶蜂是重庆市近年来马尾松林内发生较严重的食叶害虫,以幼虫取食针叶危害,1a发生1代,幼虫老熟后下地入土作蛹室,以预蛹态越夏越冬,翌年2月下旬开始化蛹,3月中旬开始羽化,4月下旬幼虫开始孵化,6月上旬幼虫进入暴食期并开始老熟下地。幼虫出现期约90d,雄性6龄,雌性7龄。运用5种水剂、5种粉剂、3种烟剂分别对幼虫进行防治试验,结果表明,2～3龄幼虫期是防治的最佳时机,灭幼脲III号和林虫净两种水剂,药效可达89%以上,杀虫双、甲氨硫磷、氧化乐果水剂单株注干药效都在90%以上;粉剂2‰多效杀虫灵、2‰森保I号、速效白僵菌药效分别为91.4%、80%、75.4%;烟剂敌杀死、灭杀毙药效分别为96.9%、85.8%。Cephalcia pinivora was an important leaf pest of Pinus massoniana in Chongqing. It had one generation a year and overwintered as prepupa in the soil and began to pupate in the last ten days of February the next year. In mid March , the adults emerged and the larva hatched in the last ten days of April. In the first ten-day of June they came down trees and went into soil. Larva durition was about 90 days, and there were 6 instars for male and 7 instars for female. Studies showed that application of liquid, smoke, power pesticide could effectively control this sawfly. During the larval period, the best control time was around the 2^nd and 3^rd instars.
