中国枯叶蛾科昆虫地理分布及其与环境的相关性

运用GIS操作平台对我国枯叶蛾科 7个属的地理分布进行研究 ,结果表明枯叶蛾科 7个属的松毛虫主要分布于我国的东部和南部 (除松毛虫属的个别物种在我国西北部有分布 ) .栎毛虫属主要分布于我国的北方中高纬度地区 (N2 8°～ 4 0°之间 ) ;丫毛虫属分布于我国的最南方低纬度地区 (N2 6°以南 ) ;大毛虫属和云毛虫属主要分布于我国的中低纬度地区 (N2 3°～ 34°和N2 3°～ 37°) ;松毛虫属、杂毛虫属和小毛虫属 3个属在我国的高、中、低纬度地区均有分布 (N19°～ 5 2°) .除丫毛虫属与大毛虫属及栎毛虫属分布区之间几乎不重叠之外 ,7个属的松毛虫的分布区大多数有不同程度的重叠 ,其中松毛虫属、杂毛虫属、小毛虫属的分布区几乎完全重叠 .各属的平均体长、平均翅展与经纬度之间并不存在简单的线性相关关系 ,而雌性体长的变异与经度成一定的负相关 .该文分析了分布与相对湿度、年均气温、降雨量和温暖指数之间的关系 ,并推测了枯叶蛾科 7个属的大致的系统发育关系

Geographical distribution of Lasiocampidae in China and its relationship with environmental factors

On the platform of GIS geographical distribution of Lasiocampidae in China is studied. Seven genera of Lasiocampidae are mainly distributed in south China and east China (except for individual species of Dendrolimus). Paralebeda is in the north of China (28°--40°N) while Metanastria is located in the south of China(south of 26°N); Lebeda and Hoenimnema are distributed at middle and low altitude; Distribution areas of other three genera are across wide range of latitude between 19°N and 52°N in China. Except of Metanastria, Lebeda and Paralebeda the distribution areas of pair-wise other genera are overlapped to different extent,and that between Dendrolimus, Cyclophragama and Cosmotriche are almost overlapped completely. Body length and wing width among seven Lasiocampidae genera are significantly different with Lebeda the largest and Cosmotriche the smallest. The variation of female body length is negatively correlated with the longitude of distribution center of seven genera. Relationships between distribution of every genus and annual relative humidity, annual temperature, annual radiation and Warmth index (WI) are discussed. Additionally, putative phylogeny of seven genera of Lasiocampidae are constructed.
