New Records of Korean Whiteflies (Hemiptera: Aleyrodidae)

Four aleyrodid species, Aleuroclava montanus (Takahashi), Asterobemisia atraphaxius (Danzig), Pentaleyrodes yasumatsui Takahashi, and Rhachisphora styraci (Takahashi) are newly recorded in the Korean fauna of whiteflies (Aleyrodidae).     

Host plants and natural enemies of Bemisia tabaci (Hemiptera: Aleyrodidae) in China

Abstract The sweetpotato whitefly, Bemisia tabaci, has been a destructive pest in China for over the past two decades. It is an extremely polyphagous insect, being recorded feeding on hundreds of host plants around the world. Potential host plants and natural enemies of B. tabaci in the south, southeast, middle, north and northwest of China were investigated during the last decade. In total 361 plant species from 89 families were recorded in our surveys. Plants in the families Compositae, Cruciferae, Cucurbitaceae, Solanaceae and Leguminosae were the preferred host species for B. tabaci, which therefore suffered much damage from this devastating pest due to their high populations. In total, 56 species of parasitoids, 54 species of arthropod predators and seven species of entomopathogenic fungi were recorded in our surveys. Aphelinid parasitoids from Encarsia and Eretmocerus genera, lady beetles and lacewings in Coleoptera and Neuroptera were found to be the dominant arthropod predators of B. tabaci in China. The varieties of host plant, their distribution and the dominant species of natural enemies of B. tabaci in different regions of China are discussed.     

浙江地区梨树上粉虱类害虫种类初记

为摸清浙江地区梨树上粉虱类害虫种类,通过采集梨树上的粉虱伪蛹制作玻片标本后进行观察鉴定.通过形态学研究,共鉴定出梨树粉虱6属、8种,其中梨树寄主新记录种6种,分别为马氏粉虱Aleurolobus marlatti(Quaintance)、杨梅粉虱Parabemisia myricae(Kuwana)、番石榴白棒粉虱Al...     

The whiteflies (Hemiptera: Aleyrodidae) of Europe and the Mediterranean Basin

The whitefly fauna of Europe and the Mediterranean Basin comprises 56 species that are considered to be native or naturalized, accommodated within 25 genera. Presented here are a check-list, an identification key to puparia, and a brief account of each species including its distribution and host-plant range. The puparium of each species is illustrated. One new nomenclatural combination (Aleuroclava similis, from Aleurotuberculatus) and two new synonymies (Parudamoselis kesselyaki with Ceraleurodicus varus, Asterobemisia nigrini with A. paveli) are proposed. Three nominal species (Aleurodes capreae, A. fraxini, and Aleyrodes campanulae) are here treated as nomina dubia. Species which, in the study area, have only been recorded from glasshouses are discussed. Four additional species, not yet recorded from the region, are included in the discussion, two of them because a particular quarantine risk is perceived and two because they are notifiable pests in European Union quarantine legislation.     

利用mtCOI PCR-RFLP技术鉴定中国境内九个烟粉虱隐种

烟粉虱Bemisia tabaci (Gennadius)是一个物种复合体, 包括31个以上形态上无法区分的隐种, 其中少数隐种是世界性入侵害虫。目前, 在中国境内分布有2个入侵隐种和13个土著隐种。快速、 高效的鉴别方法对掌握烟粉虱田间发生规律及制定相关防控策略具有重要意义。然而到目前为止, 除了mtCOI基因测序比对外, 尚未有一种简便的方法可以有效地区分多个烟粉虱隐种。本研究采用mtCOI PCR-RFLP技术, 单独或组合使用TaqI, VspI, Van91I, NcoI和FokI这5种限制性内切酶, 酶切烟粉虱mtCOI的PCR扩增片段, 鉴别分布在中国境内的9个烟粉虱隐种。结果表明, 单独使用TaqI酶切, 可鉴别出MEAM1和China 1两个隐种, 使用TaqI+NcoI分步酶切可鉴定出MED和Asia 1两个隐种, 使用TaqI+Van91I分步酶切可鉴定出Asia II 3和Asia II 9两个隐种, 使用TaqI+VspI+FokI分步酶切可鉴定出Asia II 1, Asia II 6和Asia II 7 3个隐种。本研究为高效鉴别中国境内的多个烟粉虱隐种提供了方法。
