The morphological characteristics, life history and biological properties of Mansoniella cinnamomi were observed based on systematical investigations both in field and laboratory. The results showed that M. cinnamomi had 6-7 generations a year in Zhejiang province, and overwintered with eggs in leaf stalk and vein. Adult and nymph could be found simultaneously from mid-May to December. The breakout mechanism of M. cinnamomi was discussed, and the control methods were put forwarded based on its biological properties.%通过林间调查和室内试验对樟颈曼盲蝽的形态特征、年生活史、各虫态习性进行了较为系统的观察描述,结果表明,樟颈曼盲蝽在浙江1年发生6～7代,以卵在香樟叶柄和叶脉内越冬.自5月中旬起至12月,若虫和成虫同时可见.对该虫的爆发机制进行了探讨,香樟高密度、大面积连片种植可能是诱发樟颈曼盲蝽大规模爆发的重要原因,并围绕其生物学特性提出了防治策略.
