摘要
为明确福建漳江口红树林国家级自然保护区昆虫群落结构及多样性特征,在保护区上、中、下游的不同潮位(高、中、低)选取了桐花树、秋茄、白骨壤纯林以及桐花树-秋茄、白骨壤-秋茄混交林进行昆虫群落调查。连续8个月(3—10月)的调查共采集昆虫223种,隶属于11目62科。7、8月的昆虫物种最丰富,7月采集的昆虫个体数量最多,为1838头,8月的昆虫Margalef丰富度指数最高,达11.53091;3—5月和9—10月的昆虫物种丰富度较低,其中,3月采集的昆虫个体数量最少,为545头,昆虫Margalef丰富度指数仅为5.23744。共鉴定出直接危害红树林的害虫有13种,其中,11种害虫为害叶片,3种害虫为害枝干。白骨壤林分的害虫种类最多,共有8种,占害虫种类数量的61.54%。鳞翅目是漳江口红树林昆虫群落的优势类群,且昆虫的种类和数量随月份的变化趋势为7月>9月>8月>10月>5月>6月>4月>3月;主要害虫种类为棉古毒蛾、咖啡蠹蛾、素木绿刺蛾、荔枝异形小卷蛾等。
To clarify the insect community structure and diversity characteristics in the Zhangjiangkou Mangrove National Nature Reserve,investigations were conducted in pure stands of Aegiceras corniculatum,Kandelia candel,and Avicennia marina,as well as mixed stands of Aegiceras corniculatum-Kandelia candel and Aegiceras marina-Kandelia candel across different tidal zones(high,medium,and low)in the upper,middle,and lower reaches of the reserve.From March to October,223 insect species belonging to 62 families of 11 orders were collected.The period of June to August exhibited the highest insect species richness,with July recording the maximum abundance(1838 individuals)and August showing the highest Margalef richness index(11.53091).Lower species richness was observed from March to May and from September to October,with March having the lowest abundance(545 individuals)and Margalef richness index(5.23744).13 pest species directly damaging mangroves were identified,including 11 leaf-feeding and 3 branch-boring species.Aegiceras marina stands hosted the highest pest species(8 species,61.54%of total pests).Lepidoptera was dominant insect order,and the species richness and abundance of insects varied across months,showing a descending order of July>September>August>October>May>June>April>March.Major pests included Orgyia postica,Polyphagozerra coffeae,Parasa shirakii,and Cryptophlebia ombrodelta.
