摘　　要：【目的】分析Ap的种群动态的信息,研究As种群的种群动态规律性,对比分析2个不同粉虱种群的消长动态及差异性,为进一步揭示2个种群间的关系提供依据。【方法】2022~2023年连续2年在室外条件下选择当地主要种植的甘蓝、青菜(油白菜)、油麦菜及入侵菊科杂草毒莴苣作为供试植物,探讨欧洲甘蓝粉虱Aleyrodes proletella L.和Aleyrodes sp.的寄主选择性,比较研究在不同寄主植物上,2种粉虱的种群消长动态。【结果】毒莴苣和油麦菜是Aleyrodes proletella L.种群最主要的春夏寄主,油麦菜是主要的夏秋寄主;毒莴苣是Aleyrodes sp.种群春夏秋最主要的寄主;2种寄主均有利于若虫取食、存活和发育,可使2种欧洲甘蓝粉虱种群密度达到较高的水平;甘蓝为2种粉虱种群主要的越冬寄主。7月下旬至9月上旬是混合种群在毒莴苣上的为害盛期,其卵、若虫、伪蛹和成虫的总密度为40.7头(粒)/cm^(2);8月上旬,混合种群若虫、伪蛹的密度在油麦菜上达到最高峰,为0.7头/cm^(2)。在寄主毒莴苣上,Aleyrodes proletella L.种群虫口密度在6月下旬达到最高水平,为0.54头/cm^(2),之后因天敌寄生和迁移至油麦菜等其他寄主植物,虫口密度逐渐开始下降并趋于零;在油麦菜上,Aleyrodes sp.种群若虫暴发的时间相对滞后。【结论】Aleyrodes proletella L.和Aleyrodes sp.2个种群的消长动态具有显著性差异。【Objective】That have invaded at present,the information on the population dynamics of Ap is limited,and there are no research reports on the regularity of the population dynamics of As population.Therefore,it is urgent for us to compare and clarify the dynamics and differences of growth and decline between two different populations of Aleyrodes,in order to provide a basis for further revealing the relationship between the two populations.【Methods】In 2022-2023,we selected B.oleracea convar.capitata L.,Brassica chinensis var.chinensis and Lactuca sativa var.longifolia Lam,which mainly grew in this area,and the invasive Asteraceae weed L.serriola L as test plants under outdoor conditions for two consecutive years,the host selectivity of the Aleyrodes proletella L.and Aleyrodes sp.was explored and the population growth dynamics of the two whiteflies comparatively on different host plants were analyzed.【Results】The results showed that L.serriola L.and Lactuca sativa var.longifolia Lam.were the most dominant spring and summer hosts of Aleyrodes proletella L.populations,and Lactuca sativa var.longifolia Lam.r was the primary summer and fall host;L.serriola L.was the main host of the Aleyrodes sp.population in spring,summer and autumn.Both hosts were highly favorable for feeding,survival,and development of the two population of Aleyrodes.,which could lead to high population densities of two population of Aleyrodes.B.oleracea convar.capitata L.was the primary overwintering host for two whitefly populations.Field investigation showed that from late July to early September,the maximum damage period of mixed population on L.serriola L.was observed,and the total density of eggs,nymphs,pseudopupa and adults was 40.7 head(grain)/cm^(2).In early August,the density of nymphs and pseudopupa of mixed population reached the highest in Lactuca sativa var.longifolia Lam.,which was 0.7 head/cm^(2).On the host L.serriola L.,the population density of Aleyrodes proletella L.reached the highest level in late June,which was 0.54
