摘　　要：首次发现和报道了褐袋蛾Mahasena colona Sonan对红树植物桐花树Aegiceras corniculatum的危害。通过室内饲养和野外观察,对褐袋蛾的形态特征、生物学特性进行了初步研究。结果表明,褐袋蛾在广西1 a发生1代,有可能是由越南一侧红树林传入,该虫耐水淹和耐饥饿能力都较差,不大可能在广西红树林内大面积扩散,但对无瓣海桑存在一定的威胁。Mahasena colona was first reported in Aegiceras corniculatum. Based on the field observation and lab rearing, the morphological characteristics and bionomics of Mahasena colona were studied. The results showed that M. colona occured one generation a year in Guanxi. It may be introduced from Vietnam. Its abitity of resistance to flood and starvation was poor and the possibility of large area spread in mangrove forest in Guangxi was little,but it was still a threat to Sonneratia apetala.
