摘　　要：红树植物是分布于热带、亚热带海岸潮间带的木本植物群落,也是唯一能形成海岸类型的活的生物群体。近年来,红树林害虫海榄雌瘤斑螟对整个红树林海榄雌种群造成严重危害,对湿地红树林的保护与利用构成严重威胁。为了探索对红树林地区生物及周围环境不会造成危害、不污染环境和杀伤天敌的有效的害虫防控技术模式,2007—2009年采用寄生蜂、寄生蜂携带病毒的"生物导弹"结合Bt的生物防控技术手段,对深圳内伶仃-福田国家级自然保护区红树林害虫海榄雌瘤斑螟进行防治试验。结果表明,"生物导弹"防治区和Bt防治区的叶片被害率分别从防治前57.1%和67.7%下降到31.9%和38.1%,几种生物防治技术的结合对害虫的防治效果达到44.3%～74.2%,使红树林害虫海榄雌瘤斑螟的危害得到有效控制。Mangroves are woody plant communities which occur in the intertidal zones on tropical and subtropical coast.In recent years,the pest of mangroves,Acrobasis sp.,have done harm to the species of mangrove Avicennia marina,and posed a serious threat on wetland protection and utilization of mangroves.In order to seek effective pest control methods,including natural enemies,egg parasitoid,and insect virus combined with Bt,the techniques of biological control were conducted in Neilingding-Futian National Nature Reserve of Guangdong.The results showed that,field experiments from 2007 to 2009 confirm the techniques of biological control combined with parasitic wasps,insect virus ＂bio-missile＂,and Bt can effectively control the mangroves pests.Infected rate of leaves were decreased from 57.1% and 67.7% to 31.9% and 38.1%,respectively,and 44.3%～74.2% control effect were achieved.
