摘　　要：于2022—2023年,采用实地调查的方法对四川省内江市菊方翅网蝽(Corythucha marmorata)的分布和发生情况进行调查,并对其在内江市的入侵进行风险评估。结果表明,菊方翅网蝽在内江市中区、东兴区、资中县、威远县和隆昌市共5个县(市、区)的36个乡镇均有分布和发生,主要寄主为苏门白酒草(Erigeron sumatrensis)、小蓬草(Erigeron canadensis)、艾(Artemisia argyi)等野生杂草,危害程度暂时较轻;内江市菊方翅网蝽在多指标综合体系中的最终风险值得分为1.75,风险等级属于中度危险。说明菊方翅网蝽在内江市有进一步传播扩散的可能性,需要进行定期调查和监测。Field investigations were conducted in 2022—2023 to investigate the distribution and infestation of Corythucha marmorata in Neijiang,Sichuan Province.Futhermore,an assessment of its invasion risk was performed.The results indicated that C.marmorata has been found in 36 towns across 5 counties(cities,districts)in Neijiang,including Shizhong District,Dongxing District,Zizhong County,Weiyuan County and Longchang City.The primary host plants were wild weeds such as Erigeron sumatrensis、Erigeron canadensis and Artemisia argyi.Currently,the resulting damage was relatively minimal.The final risk value based on the integrated multi-index evaluation system of C.marmorata in Neijiang was 1.75,indicated that this pest species belongs to a medium-risk level.This suggested that C.marmorata has the potential for further spreading and dispersing in Neijiang,which requires regular investigation and monitoring.
