本研究基于中国鳞翅目50科小蛾类昆虫的寄主植物数据，探索小蛾类昆虫与其寄主植物之间的关系。对昆虫种数与寄主植物种数之间进行了相关性分析，采用了z分数法对原始数据进行标准化处理以及利用箱式图对数据进行异常值检测，并对检测的结果分科进行食性分析。昆虫种数与寄主植物种数呈极显著正相关（P<0.01），相关系数为0.860；异常值检测结果显示蝙蝠蛾科、细蛾科、祝蛾科、织蛾科、斑蛾科、羽蛾科、卷蛾科和草螟科8科数据异常；这8科小蛾类昆虫除了织蛾科和祝蛾科以腐食性为主外都是植食性，其中植食性昆虫包括单食性的斑蛾科，寡食性的羽蛾科和细蛾科以及多食性的蝙蝠蛾科。而卷蛾科中黄卷蛾族和小卷蛾族的幼虫以多食性较为常见，花小卷蛾族幼虫则以单食性为主。草螟科中斑野螟亚科和禾螟亚科以单食性为主；草螟亚科和野螟亚科以寡食性为主。中国小蛾类昆虫与其寄主植物种数之间存在着正相关关系；研究结果为小蛾类分类研究以及农林害虫防治奠定了理论基础。

英文摘要:

The relationship between micro moths and their host plants is investigated based on the host plant data of 50 Microlepidopteran families in China.The correlation between the number of insect species and their host plants is analyzed.The z.score is adopted to standardize the original data, and the boxplot is used to detect the abnormal value of the data with analysis of the feeding habit of the detected insect families.The results showed that the number of insect species was positively correlated with the number of host plants (P< 0.01), with correlation coefficient being 0.860.The results of the aberration test showed that data of Lecithoceridae, Oecophoridae, Hepialidae, Gracillariidae, Zygaenidae, Pterophoridae, Tortricidae and Crambidae were abnormal. Lecithoceridae and Oecophoridae are mostly saprophagous.Among the six phytophagous families, Zygaenidae is monophagous, Pterophoridae and Gracillariidae are oligophagous, and Hepialidae is euryphagous.However, the larvae of Archipini and Olethreutini in Tortricidae are mostly euryphagous, and those of Eucosmini are mostly monophagous.In Crambidae, Spilomelinae and Schoenobiinae are monophagous, and Crambinae and Pyraustinae are oligophagous. It reveals that a positive correlation between micro moths and their host plants in China exists. The results lay a theoretical foundation for the taxonomic study of micro moths as well as for the pest control in agriculture and forestry.
