摘要
银胶菊Parthenium hysterophorus是一种全球入侵性杂草,广泛分布于热带和亚热带地区。银胶菊叶甲Zygogramma bicolorata作为银胶菊天敌昆虫,对该杂草具有较好的防治效果。预测银胶菊及其生防天敌银胶菊叶甲的适生区可以为其生物防治和区域管理提供参考。因此,本研究基于两个物种的全球发生点和21个环境变量,利用MaxEnt模型预测了银胶菊和银胶菊叶甲在近现代气候条件下的全球适生区。研究结果表明,影响银胶菊适生区分布的主要因子为最冷季节平均温(bio11)、最湿月份降水量(bio13)、最湿季节平均温(bio8)和人类影响指数(HII);影响银胶菊叶甲适生区分布的主要因子为最暖季节平均温(bio10)、最湿月份降水量(bio13)、等温性(bio3)和人类影响指数(HII);银胶菊和银胶菊叶甲在全球的适生区面积分别为5426.79×10^(4)km^(2)和1410.59×10^(4)km^(2),适生区重叠面积为1357.66×10^(4)km^(2),主要分布在亚洲(巴基斯坦、印度、中国南部以及大部分东南亚国家),北美洲墨西哥湾沿岸(美国中低纬度地区、墨西哥东部沿海地区),非洲西部的尼日尔河流域和东南部的赞比西河流域(赞比亚、尼日利亚等),南美洲中南部(巴西东南部地区、阿根廷北部地区等)。本研究结果为在适生区重叠区域内利用银胶菊叶甲防治银胶菊提供了依据。
Parthenium hysterophorus is an invasive weed globally,widely distributed in tropical and subtropical regions.The leaf beetle Zygogramma bicolorata,a natural enemy of P.hysterophorus,has shown to be an effective biological control agent in some countries/regions.Predicting the suitable habitats for P.hysterophorus and Z.bicolorata can provide valuable information for its biological control and regional management.Therefore,this study used the MaxEnt model,based on species global occurrence points and 21 environmental variables,to predict the suitable habitats for P.hysterophorus and Z.bicolorata worldwide under nearly current climate.The model suggested that the main factors affecting the distribution of suitable habitats for P.hysterophorus were mean temperature of coldest quarter(bio11),precipitation of wettest month(bio13),mean temperature of wettest quarter(bio8),and human influence index(HII).While the main factors affecting the distribution of suitable habitats for Z.bicolorata were mean temperature of warmest quarter(bio10),precipitation of wettest month(bio13),isothermality(bio3),and human influence index(HII).The model prediction indicates that the area of potential suitable habitats for P.hysterophorus and Z.bicolorata were 5426.79×10^(4)km^(2)and 1410.59×10^(4)km^(2)respectively,with an overlapping area of 1357.66×10^(4)km^(2).These areas were mainly distributed in Asia(Pakistan,India,Southern China and most Southeast Asian countries),the Gulf Coast of North America(low and middle latitudes area of the United States,and the Eastern coast of Mexico),the Niger River Basin in Western Africa and the Zambezi River Basin in Southeastern Africa,as well as Central and Southern South America(Southeastern Brazil and Northern Argentina).The results of this study provide a basis for using Z.bicolorata to control P.hysterophorus in their overlapping regions.
