摘要

线虫被认为是整个欧洲农业的主要害虫,在有利年份对罗马尼亚的玉米和向日葵作物尤其重要。本研究基于5年(2015-2019年)在罗马尼亚3个县9个地区的25个样地收集的标本,旨在评估罗马尼亚南部和东南部玉米和向日葵作物相关的点击甲虫(鞘翅目:蠓科)动物群的结构。分析资料包括3000多个标本,结果表明,click beetles有16种,隶属于8个亚科9属。在区域尺度上,优势种依次为:乌鳢(22.15%)、双斑螯虾(19.17%)、斑点螯虾(14.4%)、暗色螯虾(11.45%)、细线螯虾(9.72%)和斑点螯虾(8.84%)。分析结果表明,吉林省和Ialomița县蠓科群落的优势种为长尾蠓和横纹蠓,两者具有相似性,而与Constanța县蠓科群落的优势种为双尾蠓、横纹蠓和横纹蠓存在净差异。所得结果为罗马尼亚南部玉米和向日葵作物线虫区系数据库的建立奠定了基础,为进一步开展害虫综合治理提供了基础信息。

Diversity of Click Beetle Associated with Maize and Sunflower Crops from South and SouthEastern Romania
Wireworms are considered key pests in agriculture across Europe, and are particularly important in Romania for maize and sunflower crops in favorable years. The present study aimed to evaluate the structure of the click beetle (Coleoptera:Elateridae) fauna associated with corn and sunflower crops in the south and south-east of Romania, based on the specimens collected during 5 years (2015-2019), in 25 plots from 9 localities belonging to 3 counties. The analysed material included a number of over 3000 specimens and the results showed a significantly high click beetles diversity represented by 16 species and a variety assigned to 9 genera and 8 subfamilies. At regional scale, dominant species were found: Agriotes ustulatus (22.15%), Drasterius bimaculatus (19.17%), Agriotes sputator (14.4%), Agriotes obscurus (11.45%), Agriotes lineatus (9.72%) and Selatosomus latus (8.84%). The analysis of the data highlights the similarity between the Elateridae communities in Călăraşi and Ialomița Counties, where the dominant species were A. ustulatus and A. sputator, and their net difference with the click-beetles communities in Constanța County, where the dominant species were D. bimaculatus, S. latus and A. sputator. The obtained results represent the starting point of a database on the wireworm fauna associated with maize and sunflower crops in Southern Romania, and bring basic information’s needed for further development of Integrated Pest Management.

期刊介绍: The Journal ROMANIAN AGRICULTURAL RESEARCH is an “open access” one, which publishes original articles, short communications, presenting new scientific results – theoretical, experimental and technical – on plant breeding and genetics, physiology, biotechnology, mineral nutrition and plant protection, in field crops. Reviews on up-to date subjects and recent research, preferably from Eastern Europe, may also be published.
