摘　　要：棉蝗在长乐沿海木麻黄林分中曾两度暴发成灾,通过多年观察分析,认为棉蝗暴发成灾的诱因主要与害虫生物学特性、寄主、生态环境及经营管理等因素有关。The outbreak of Chondracris rosea rosea occurred twice in the casuarina stands along the coast in Changle County. Factors such as the bionomics of the insect, host, environment and management were correlated with the outbreaks.
