外来害虫椰心叶甲入侵灾变的生态学基础及控制技术体系

椰心叶甲Brontispa longissima(Gestro)是一种重要的寄生在棕榈科植物上的害虫,2002年入侵海南并暴发成灾,导致椰子、槟榔等严重减产,严重威胁我国椰子、槟榔产业的健康持续发展,同时对南方沿海地区的绿色生态安全和热带自然景观构成了巨大威胁。经过10多年的研究,在阐明该虫发生危害规律和入侵成灾机理的基础上,研发和集成创新了应急防控与持续控制关键技术体系,并较为广泛地应用于南方椰心叶甲入侵发生区域,取得了显著的效益。

Ecology basis and control technology system of invasion and outbreak of alien pest Brontispa longissima

Palm leaf beetle Brontispa longissima (Gestro)] is an important Palmae plant parasitical pest. It invaded Hainan in 2002, then broke out, resulted in serious reduction of coconut and betel nut production, and seriously threatened the healthy and sustainable development of the industry of coconut and betel nut in China. At the same time, it posed a huge threat to the green ecological security and tropical natural landscape in the southern coastal areas. After researching for more than 10 years, the key technology system of emergency control and sustainable management were developed and integrated based on clarifying the occurrence and damage rule, and the invasion mechanism of the pest. The technology system has been widely used in the invasive area of the pest, and achieved remarkable benefits.
