摘　　要：红点唇瓢虫(Chilocorus kuwanae)是白蜡蚧最重要的捕食性天敌之一,对其在贵州的潜在适生区进行预测可以为全省白蜡蚧养殖合理布局和白蜡蚧天敌预防提供科学依据。运用MaxEnt模型,结合地理信息系统(GIS)对红点唇瓢虫在贵州的潜在分布区进行分析。红点唇瓢虫在贵州省的适生范围为104.75°~109.59°E,24.99°~29.21°N,其中,高、中适生区主要集中于铜仁市、黔东南州、黔南州大部、遵义市中东部和贵阳市东部等地。红点唇瓢虫高、中适生区与贵州的白蜡产蜡区高度重合,对区域白蜡产业发展构成影响,在规划、发展白蜡产业时应予以重视;与之相反,红点唇瓢虫的中、高适生区却与白蜡种虫产区分离,客观上有利于白蜡种虫生产。此外,最暖季节降水量、温度季节性变化、最湿季度降水量和年均降水量是影响红点唇瓢虫分布的主导环境因子。在4个主导环境变量中,最暖季节降水量、最湿季度降水量和年均降水量3个环境因子贡献率高达70.4%,约为温度季节性变化所占贡献率的3倍多,因此,降水量可能是影响红点唇瓢虫分布的决定性环境因子。Chilocorus kuwanae is one of the most important predatory natural enemies of Ericerus pela in Guizhou Province of China.The accurate and rapid prediction of its potentially suitable areas can provide scientific basis for the rational layout of Ericerus pela culture for the prevention of natural enemies.In this study,the potentially suitable areas of C.kuwanae were determined in Guizhou using MaxEnt model and GIS.The results showed that the suitable range of C.kuwanae was located at 104.75°-109.59°E,24.99°-29.21°N.The highly and moderately suitable areas were concentrated mainly in Tongren,Qiandongnan,most of Qiannan,central-eastern Zunyi and eastern Guiyang,indicating the highly overlap areas with the wax production.There was an impact on the development of regional E.pela industry,when planning and developing ash industry.On the contrary,the moderately and highly suitable areas of C.kuwanae were separated from seed production areas,which was beneficial to ash seed cultivation.In addition,four dominant environmental varibles affecting the distribution of C.kuwanae were the precipitation of warmest quarter,temperature seasonality,precipitation of wettest quarter,and annual precipitation.Among them,the precipitation of warmest quarter,precipitation of wettest quarter and annual precipitation were greatly contributed as much as 70.4%,which was about three times more than that of temperature seasonality.Therefore,the precipitation can be expected to serve as the decisive environmental varible on the distribution of C.kuwanae.
