Abstract: 研究了上海市水源涵养林内樟颈曼盲蝽(Mansoniella cinnamomi(Zheng et Liu,1992))的生活史和生物学习性,以及若虫的龄期划分和各龄若虫的形态特征.依据樟颈曼盲蝽若虫头宽值频次和形态特征,其若虫共分5龄,1~5龄若虫的头宽值分别为(0.23±0.03)、(0.34±0.02)、(0.47±0.03)、(0.57±0.02)、(0.68±0.03) mm,并详细描述了各龄若虫的形态特征.该虫在上海地区一年发生4代,以卵在叶柄、叶主脉及嫩梢皮层内越冬,具有明显的世代重叠现象.确定了樟颈曼盲蝽各世代的发生历期,编制了其在上海地区的生活史表,详细观察记录了成虫的羽化、交尾、产卵等习性和若虫的活动、取食及脱皮等习性.
