蔓长春花绣线菊蚜消长动态及耐寒性研究李融梅周玲琴毕庆泗陈连根摘要[目的]探明蔓长春花上的绣线菊蚜在上海地区的消长动态。[方法]调查绣线菊蚜的寄主及危害程度;于2018年11月—2019年11月，抽样调查野外蔓长春花上绣线菊蚜的消长动态;进行了过冷却点测定及低温冷冻试验。[结果]绣线菊蚜的寄主达32种;蔓长春花上的绣线菊蚜种群于4月下旬及11月下旬分别出现1次大高峰，而1—3、6—7月上旬几乎未见，其余时段以低水平发生，全年未见性蚜;绣线菊蚜各虫态的过冷却点均低于-15℃;在-13℃下放置24、48h，蔓长春花上的绣线菊蚜的存活率均在70%以上。[结论]在上海地区，绣线菊蚜在蔓长春花上不以卵越冬，而是迁飞至设施栽培内进行繁衍、过冬。绣线菊蚜有较强的耐寒性，进一步佐证了绣线菊蚜以孤雌蚜过冬的猜测。探讨了利用蔓长春花绣线菊蚜饲养天敌，进而控制靶标蚜虫，构建新的载体植物系统的可能性。关键词绣线菊蚜;消长动态;耐寒性;上海S433.39A0517-6611（2020）15-0160-03doi：10.3969/j.issn.0517-6611.2020.15.046开放科学（资源服务）标识码（OSID）：StudyontheGrowthandDeclineRulesandColdToleranceofAphiscitricolaVanderGootonVincamajorLIRongmei1，ZHOULingqin2，BIQingsi1etal（1.ShanghaiBotanicalGarden，Shanghai200231;2.ShanghaiPutuoDistrictCommunityGreeningManagementOffice，Shanghai200062）Abstract[Objective]ToexplorethegrowthanddeclinerulesofAphiscitricolaVanderGootonVincamajorinShanghai.[Method]ThehostplantsandthedamagedegreeofAphiscitricolaVanderGootwereinvestigated;fromNovember2018toNovember2019，thegrowthanddeclinerulesoftheaphidsonVincamajorwasinvestigatedbythefieldsamplingsurvey.Thesupercoolingpointandthefreezingtestwerealsoconductedfortheaphids.[Result]Therewere32speciesofhostplantsforAphiscitricolaVanderGootOnVincamajor，therewasapeakoftheaphidpopulationeachinlateAprilandlateNovember，theaphidsbecameveryrarefromJanuarytoMarch，JunetoearlyJulyrespectively，andoccurredatalowlevelintherestoftheyear.Nosexuparaoftheaphidwasfoundinthewholeyear;Thecoldtoleranceexperimentoftheaphidshowedthatthesupercoolingpointofeachaphidtypeorstatewaslowerthan-15℃;whentheaphidswerekeptat-13℃for24and48hrespectively，thesurvivalrateswereover70%.[Conclusion]InShanghai，AphiscitricolaVanderGootdidnotoverwinteraseggsonVincamajor，butmigratetotheprotectedcultivationforreproductionandoverwintering.Itwasfurtherconfirmedthattheaphidoverwinterasviviparousfemalebythecoldtoleranceexperiment.ThepossibilityofconstructinganewcarrierplantsystembybreedingnaturalenemieswithAphiscitricolaVanderGoottocontroltargetaphidswasexplored.KeywordsAphiscitricolaVanderGoot;Growthanddeclinerules;Coldtolerance;Shanghai基金項目上海市绿化和市容管理局课题“上海市绿化植物蚜虫类防控技术研究与示范”（G150305）。作者简介李融梅（1990—），女，江苏盐城人，助理工程师，硕士，从事园林植物病虫害的调查、防治等研究。*通信作者，高级工程师，从事园林植物病虫害的调查、防治等研究。-全文完-
