| 摘 要： | 舞毒蛾是一种世界性的害虫,常被分为欧洲型和亚洲型2种类型,欧洲型舞毒蛾在传入美国之后造成了巨大危害。之前报道指出亚洲型舞毒蛾的寄主范围比欧洲型舞毒蛾的广,故造成的危害和损失更大,北美植物保护组织据此对中国的高风险港口实施了船舶特别检疫措施,对我国的进出口贸易产生了巨大影响。鉴于此,本实验以16种北美和中国常见的行道树种和绿化树种作为供试树种,分析了不同寄主植物对亚洲型舞毒蛾生长发育指标的影响规律。结果表明:饲喂白桦、加杨和糖槭的幼虫可以完成生活周期。饲喂杜松、女贞、大叶黄杨、红皮云杉、合欢、杂交鹅掌楸、马尾松、黑松和白皮松的幼虫在2龄以前全部死亡。虽然2龄以前幼虫饲喂北美乔松、油松和柿树后死亡率较高,但用人工饲料将幼虫饲养至4龄以后再替换饲喂以上3种植物,幼虫的死亡率则显著下降。分析表明,亚洲型舞毒蛾低龄幼虫(1、2龄)的寄主选择范围要窄于高龄幼虫(4龄以后的幼虫)。

| Abstract: | The Asian gypsy moth(Lymantria dispar asiatica,AGM) is one of three gypsy moth subspecies that is found in Asia.European gypsy moth was introduced to USA which caused a great damage.Former study showed Asia gypsy moth could harm more kinds of trees than European gypsy moth.In this experiment,we choose 16 kinds of tree species to test host selection suitability which are common in USA or China.Statistics mortality rate,developmental duration and pupae weight to analyze the host impact on Asia gypsy moth.The result showed the larve of AGM feed on Acer saccharum,Betula platyphylla,Populus canadensi could complete life cycle.Larvae feed on Juniperus rigida,Ligustrum lucidum,Buxus megistophylla,Picea koraiensis,Albizia julibrissin,Liriodendron chinense × tulipifera,Pinus bungeana,Pinus massoniana and Pinus thunbergii all died before 2nd instar.Larvae feed on P.tabulaeformis,P.strobus and Diospyros kaki after 4th instar,mortality is lower than 2nd instar.Once the larve develop after 4th instar,host range is wider than 1st and 2nd instar. |
