摘　　要：[目的]为了给梨网蝽的综合治理提供有力的理论依据。[方法]2014～2015年,通过连续观察,研究重庆市园林植物害虫梨网蝽的生物学特性和发生规律,在室温下测定梨网蝽卵和若虫的发育历期和成虫寿命。[结果]梨网蝽在重庆一年发生5代,以成虫越冬,翌年4月中旬开始活动。一年有2次危害高峰期,分别在5～6月和8～9月。卵的平均发育历期约为12.41 d,平均孵化率为84.97%;若虫的平均发育历期为13.23 d,平均羽化率为74.43%;成虫寿命平均为15.96 d。[结论]在越冬成虫活动产卵之前进行化学药剂防治,能够获得良好的防效。[Objective]The research aimed to provide theoretical basis for the comprehensive treatment of Stephanotis（ Stephanotis） nashi Eaaki et Takeya. [Method] We studied the bionomics rule and the occurrence regularity of Stephanotis（ Stephanotis） nashi Eaaki et Takeya through continuous observation in Chongqing,2014 ～ 2015. And we tested the development period of egg and adult longevity of Stephanotis（ Stephanotis）nashi Eaaki et Takeya at room temperature. [Result] Stephanotis（ Stephanotis） nashi Eaaki et Takeya has 5 generations per year in Chongqing area,and it overwinters as adult. The overwintering adults begin to move in the middle of April in next year. There are two peak stages in a year,which respectively appear from May to June and from August to September. The average development period was 12. 41% and the average hatchability of egg was 84. 97%. The average development period was 13. 23 d and the average eclosion rate of nymph was 74. 43%. The average longevity of the adult was 15. 96 d. [Conclusion]Before the over wintering adults begin to more and lay eggs,chemical control can obtain good control effects.
