| 摘 要： | 蔗扁蛾(Opogona sacchari),隶属鳞翅目(Lepidoptera)辉蛾科(Hieroxestidae)扁蛾属(Opogona)(杨集昆等,1997),是近年来从境外传人我国的一种重要林业危险性有害生物(程桂芳等,1997).该虫寄主广泛,据资料报道(商晗武等,2003),目前已发现寄主植物28科87种8变种,其中,国外报道24科6种4变种,国内14科55种2变种,主要危害巴西木(Dracaena fragrans)、发财树(Pachira macrocarpa)、风梨(Ananas comosus)、一品红(Euphorbia pulcherrima)、朱顶兰(Amaryllis vittata)、木棉(Bombax malabaricum)、大王椰子(Roystonea regia)等观赏植物,我省新发现还能危害柳树(Salix sp.)、紫藤(Wisteria sinensis)、龙爪槐(Sophora japonica var.pendula)等本地绿化树种.它已对我国花卉苗木和林业生产造成严重威胁.为控制疫情扩散蔓延,国家林业局将其列入了林业检疫性有害生物名单. |

| Abstract: | The internal transcribed spacer (ITS) of Opogona sacchari, a important quaratine pest, from different hosts was studied by using the special primers designed by the highly conserved region sequence of 18S and 28S rDNA region, and the ITS sequences of Opogona sacchari from diffirent hosts were compared. The total length of O. sacchari ITS1, ITS2 and 5.8S rDNA is 987 bp. The average of G C contents is 47.2%. Length of ITS1 and ITS2 fragment is 443 bp and 358 bp. The ITS1 and ITS2 from different hosts are identical or unsignificantly difference. |
| Keywords: | Opogona sacchari internal transcribed spacer host quarantine |
