中文摘要：马尾松腮扁叶蜂Cephalcia pinivora Xiao et Zeng是腮扁叶蜂属的一个新种［1］。主要分布在重庆和四川等地，严重危害马尾松。在重庆1年1发生代，成虫发生期约80 d，3月中旬开始羽化，雄虫先羽化出土，雌虫在羽化高峰期才开始出土。未交配雌虫能孤雌生殖。用2.5%溴氰菊酯等7种烟剂喷烟和3‰溴氰菊酯粉剂对成虫进行防治试验，结果表明，成虫羽化盛期后3～5 d（4月上旬）是防治成虫的最佳时机，烟剂防治效果好的可达80％以上，粉剂效果也可达86%以上。
英文摘要：Cephalcia pinivora Xiao et Zeng is a new species of genus Cephalcia, which attacked Chinese red pine, Pinus massoniana Lamb., and caused severe damage in Chongqing and Sichuang. This species had one generation per year. In late March, adults began to emergence, and the emergence of males is earlier than females. The life-span of adults can reach to 80 days. The unmated females could only produce male progeny by parthenogenesis. It was the most effective control period that 3～5 days after the peak period (early April) of adult emergence. The control efficacy reached over 80% with 2.5% deltamethrin aginist adults. The control efficacy reached over 86% with 3‰ Yulinbao DP against adults.
