摘要

在塞尔维亚,蚜虫出现在瓜类,包括油籽南瓜上的动物群调查很少。采用黄水诱捕器测定塞尔维亚葫芦蚜的种类多样性,并监测其飞行活动。2009 - 2011年共采集标本1447份,鉴定蚜类57个。2009年捕获蚜虫总数最多(755只),2010年和2011年分别为203只和489只。种类最多的是蚕豆蚜(15%)、桃蚜(13.4%)和棘蚜(11.7%),其次是灰蚜(6.4%)和棉蚜(5.6%)。除A. corni外,它们都被报道为葫芦病毒的有效载体。这5种蚜虫占本研究收集蚜虫种类总数的52.1%。在油籽南瓜作物中发现的57个分类群中,17个是ZYMV的载体,18个是WMV的载体,15个是CMV的载体。一般来说,在总共57个分类群中,已知有25个是塞尔维亚存在的三种病毒中至少一种的载体。在三年调查期间收集的总共1447个标本中,917个(63.4%)是三种病毒中至少一种的带菌者。在3年的调查中,油籽南瓜单株经常被棉蚜定殖。研究结果表明:塞尔维亚油籽南瓜产地在蚜虫类群中属中等至中等,总香农-韦弗指数在1.8 ~ 2.8之间。2009年Backi Petrovac I地区的Shannon-Weaver指数最高(2.8),2010年Kisac地区的Shannon-Weaver指数最低(1.8)。几乎所有作物的Shannon-Weaver多样性指数都在调查的第二周或油籽南瓜生长的早期达到最大值,此时植株有5-6片真叶或正处于开花期,此时潜在的病毒感染可能导致显著的产量损失。

Diversity and flight activity of aphid species as potential vectors of oilseed pumpkin viruses in Serbia
The fauna of aphids appearing on cucurbits, including oilseed pumpkin have been poorly investigated in Serbia. Yellow water traps were used to determine the diversity of aphid species visiting cucurbits in Serbia and to monitor their flight activity. During the years 2009 to 2011, a total of 1,447 specimens were collected and a total of 57 different aphid taxa were identified. In 2009, the highest total number of aphids were caught (755), followed by 203 and 489 aphids in 2010 and 2011, respectively. The most abundant species were Aphis fabae (15%), Myizus persicae (13.4%) and Acyrthosiphonpisum (11.7%), followed by Anoecia corni (6.4%) and Aphis gossypii (5.6%). All of them, except A. corni, are reported as efficient vectors of cucurbit viruses. These five species represent 52.1% of all aphid species collected within this study. Out of 57 taxa found in oilseed pumpkin crops, 17 are known as vectors of ZYMV, 18 of WMV and 15 of CMV. Generally, 25 out of a total of 57 taxa are known as vectors of at least one of three viruses present in Serbia. From total of 1,447 specimens collected during three years of investigation, 917 (63.4%) are vectors of at least one of three viruses. Individual oilseed pumpkin plants were frequently colonized by A. gossypii during all three years of investigation. Results of this study showed that Serbian oilseed pumpkin growing localities are grouped among medium to reach in aphidofauna, according to total Shannon-Weaver index values which varied from 1.8 to 2.8. The highest value of Shannon-Weaver (2.8) was recorded in the Backi Petrovac I locality in 2009, while the lowest Shannon-Weaver (1.8) was recorded in Kisac locality in 2010. The maximum values of Shannon-Weaver diversity index in almost all crops were recorded in the second week of investigation or in early stages of oilseed pumpkin growth when plants had 5-6 true leaves or were in flowering stage, when potential virus infection could lead to significant yield losses.
