【摘要】 软蜡蚧亚科(Coccinae)隶属于半翅目(Hemiptera)胸喙亚目(Sternorryncha)蚧总科(Coccoidea)蜡蚧科(Coccidae)。蜡蚧虫体较小,生活环境隐蔽,通常寄生于植物的枝、叶、果实上;通过刺吸植物汁液,破坏植物组织、细胞,影响其进行正常的光合作用,导致植物生长畸形,叶片枯萎,甚至死亡,因此成为农、林和园艺等植物重要的害虫之一。本文对软蜡蚧亚科在国内外的研究概况,分类特征,研究材料与方法,及其在我国的地理分布进行阐述。本文共描述了中国软蜡蚧亚科4族17属50种,包括1新纪录属,5新种和6新纪录种,绘制了43个种的形态特征图,并列出了软蜡蚧亚科的分族分属分种检索表。新种:曲靖软蜡蚧Coccus qujingensis sp.nov.,勐腊小棉蜡蚧Leptopulvinaria menglaensis sp.nov.,紫荆棉蜡蚧Pulvinaria cercisioio sp.nov.,长毛棉蜡蚧Pulvinaria longsetas sp.nov.,普洱盔蜡蚧Saissetia puerensis sp.nov.。新纪录属:三鬃蜡蚧属Trijuba De Lotto,1975。新纪录种:榕软蜡蚧Coccus ficicola Choi&Lee,2018 rec.nov.,囊盖软蜡蚧Coccus latioperculatum(Green,1922)rec.nov.,眼三鬃蜡蚧Trijuba oculata(Brain,1920)rec.nov.,饰棉蜡蚧Pulvinaria decorata Borchsenius,1957 rec.nov.,杜兰盔蜡蚧Saissetia jocunda De Lotto,1957 rec.nov.,环盔蜡蚧Saissetia orbiculata De Lotto,1963 rec.nov.。对软蜡蚧亚科在中国的地理分布进行分析,结果表明:软蜡蚧亚科在我国的分布,不论是属级单元还是种级单元,东洋区均较古北区丰富,其中,华南区及华中区分布较多,说明我国软蜡蚧亚科主要分布于热带及亚热带地区。更多还原

【Abstract】 Coccinae(Hemiptera: Sternorrhyncha: Coccoidea)is one of the most important pests in agriculture,forestry and horticulture.The soft scales are tiny and secretive,usually parasitise branches,leaves and fruits of the host plants.They suck the sap of the host plants,destroy the tissue,affect photosynthesis,then lead to malformation,withering,even death.The paper reviews the historical and current research of Coccinae at home and abroad,elaborates on the identification characters and materials and methods,analyzes the geographic distribution based on the references and specimens.It describes 4 tribes,17 genera and 50 species,including 1 newly recorded genera,5 new species and 6 newly recorded species,and 43 species are illustrated,and the keys to all tribes,genera,species are provided.New species: Coccus qujingensis sp.nov.,Leptopulvinaria menglaensis sp.nov.,Pulvinaria cercisio sp.nov.,Pulvinaria longsetas sp.nov.,Saissetia puerensis sp.nov..Newly recorded genera: Trijuba De Lotto,1975.Newly recorded species: Coccus ficicola Choi & Lee,2018 rec.nov.,Coccus latioperculatum(Green,1922)rec.nov.,Trijuba oculata(Brain,1920)rec.nov.,Pulvinaria decorata Borchsenius,1957 rec.nov.,Saissetia jocunda De Lotto,1957 rec.nov.,Saissetia orbiculata De Lotto,1963 rec.nov..The geographic distribution of the Coccinae in China is analysed.As a result,both genera and species are richer in Oriental region than in Palaearctic region;more genera and species are distributed in South China and Center China.These indicate that the soft scales in China mainly occurs in tropical and subtropical areas.更多还原
