| 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 |

| Abstract: |
| According to 4 times investigations in spring (25~30 April),summer (14~19 July),autumn (5~8 October) and winter (24~29 December), the species composition of insects is rich and has a great change in the four seasons.There are about 194 species of insects (including subspecies) in this area.The number of species in spring,summer,autumn and winter is 69,166,94 and 33 respectively.In spring,the dominant species are Polyrhachis dives and Cepora nadina et al.In summer,the dominant species are Oecophylla smaragdina and Xylocopa nasalis et al.In autumn,the dominant species are O. smaragdina and Lethe confusa apara et al.In winter,they are dominated by Rodolia pumila and Aiolopus tamutus et al. |
