摘要:

通过对山口红树林保护区昆虫春季(4月25日~30日)、夏季(7月14日~19日)、秋季(10月5日~8日)和冬季(12月24日~29日)的4次调查,结果表明昆虫物种组成较丰富,1年内共有194种(含亚种)昆虫在该地区出现。同时其季节变化也很明显,春季、夏季、秋季和冬季的昆虫物种数分别为:69,166,94和33。春季的昆虫以双齿多刺蚁(Polyhachis dives)、淡紫异色粉蝶(Cepora nadina)等占优势,夏季以黄柑蚁(Oecophylla smaragdian)、竹木蜂(Xylocopa nasalis)等占优势,秋季以黄柑蚁、白带黛眼蝶中泰亚种(Lethe confusa apara)等占优势,冬季则以小红瓢虫(Rodolia pumila)、花胫绿纹蝗(Aiolopus tamutus)等占优势
