摘　　要：【目的】本研究旨在筛选出适合烟蚜茧蜂Aphidius gifuensis寄生烟蚜Myzus persicae的烟草品种、育苗方式和烟蚜来源,为烟蚜茧蜂人工繁殖和复壮提供科学参考。【方法】采用盆栽法,调查了不同烟草品种(云烟87、K326、翠碧1号和红花大金元)繁殖烟蚜若蚜、不同来源烟蚜(来自烟区、来自非烟区和室内繁殖种群)若蚜和烟草不同育苗方式(土壤育苗和湿润育苗)繁殖烟蚜若蚜时,烟蚜茧蜂成蜂对烟蚜若蚜的寄生率以及成蜂羽化率、寿命、体型大小和雌蜂比。【结果】结果表明,不同烟草品种繁殖烟蚜若蚜对烟蚜茧蜂成蜂寄生率存在显著影响。其中,在红花大金元和翠碧1号繁殖烟蚜上的烟蚜茧蜂成蜂寄生率分别比在K326繁殖烟蚜上的烟蚜茧蜂成蜂寄生率高19.00%和14.00%,但对烟蚜茧蜂的其他指标没有显著影响;不同烟蚜来源对烟蚜茧蜂寄生率也存在显著影响,其中,烟蚜茧蜂成蜂对非烟区烟蚜若蚜和烟区烟蚜若蚜的寄生率比对室内繁殖种群烟蚜若蚜的寄生率分别高20.25%和16.75%,但对烟蚜茧蜂成蜂的羽化率、寿命、体型大小和雌蜂比没有显著影响;烟草不同育苗方式对烟蚜茧蜂成蜂的寄生率无显著影响。【结论】烟蚜茧蜂对烟蚜的寄生率会因烟草品种和烟蚜来源不同而异,但不受育苗方式影响。所以在实际应用中,可通过改变烟草品种和烟蚜来源,以提高烟蚜茧蜂对烟蚜的寄生能力,达到提高烟蚜茧蜂人工繁殖效率的应用效果。【Aim】This study aims to screen the tobacco varieties,seedling raising methods and sources of Myzus persicae suitable for Aphidius gifuensis parasitization,so as to provide a scientific reference for artificial propagation and rejuvenation of A.gifuensis.【Methods】We investigated the parasitism rate of A.gifuensis adults on M.persicae nymphs and the emergence rate,life span,body size and proportion of females of A.gifuensis adults when M.persicae nymphs were bred with different varieties of flue-cured tobacco(Yunyan 87,K326,CB-1 and Honghuadajinyuan),from different sources(from tobacco region,from non-tobacco region and indoor breeding population),and bred with tobacco with different seedling raising methods(soil seedling raising and moist seedling raising)via pot experiments.【Results】The results showed that different tobacco varieties had significant effects on the parasitism rate of A.gifuensis adults on M.persicae nymphs.The parasitism rates of A.gifuensis adults on M.persicae bred with Honghuadajinyuan and CB-1 were 19.00%and 14.00%higher than that on K326,respectively.However,tobacco varieties had no significant effects on the other indices of A.gifuensis.Sources of M.persicae showed significant effects on the parasitism rate of A.gifuensis.The parasitism rates of A.gifuensis adults on M.persicae nymphs from the non-tobacco region and tobacco region were 20.25%and 16.75%higher than that on M.persicae from indoor breeding population,respectively.However,sources of M.persicae showed no significant effects on the other indices of A.gifuensis adults including emergence rate,life span,body size and proportion of females.Different seedling raising methods of tobacco did not have significant effects on the parasitism rate of A.gifuensis adults.【Conclusion】The parasitsm rate of A.gifuensis on M.persicae depends on tobacco varieties and M.persicae sources,but is not impacted by seedling raising methods.Therefore,in practical applications,the parasitic ability of A.gifuensis on M.persicae can be improved
