摘 要：
对重要林业害虫杨雪毒蛾的形态分类学和地理分布进行研究,并应用MaxEnt模型对其在我国的潜在地理分布及影响其分布的主要环境因子进行了预测和分析。分析结果表明:外生殖器性状在该物种鉴别中具有至关重要的作用;该害虫的高度适生区主要位于我国动物地理区划的华北区东部、东北区中部和南部;影响杨雪毒蛾地理分布的主要环境变量包括Bio18(最暖季降雨量)、Bio13(最湿月降雨量)、Bio16(最湿季降雨量)、Bio3(昼夜温差与年温差比值)、Bio11(最冷季平均温)、Bio1(年平均温)和Bio9(最干季平均温),其中Bio18的贡献值最高。文中提供了杨雪毒蛾的卵、幼虫、蛹、成虫和外生殖器图示,以及在我国的适生地理分布图。

摘 要：
The notorious pest Leucoma candida in forestry was studied by means of morphology.The geo-graphic distribution of L. candida was predicted and the major environmental factors were analyzed based onMaxEnt model.The analysis results show that the characters of genitalia are essential for the diagnosis of L. can-dida.Furthermore,in China fauna the highly suitable living areas of the pest are mainly located in the easternpart of north China and southern and median parts of northeast China.In addition,the main climate factors thataffect the geographic distribution of L. candida are Bio18( precipitation of warmest quarter),Bio13( precipitationof wettest month),Bio16( precipitation of wettest quarter),Bio3( isothermality),Bio11( mean temperature of col-dest quarter),Bio1( annual mean temperature) and Bio9( mean temperature of driest quarter).Among them,Bio18 presents the highest contribution value. Illustrations of the eggs,larvae,pupae,adults and genitalia areprovided,along with a map showing the potential geographic distribution of the pest in China.
