龙岩烟区烟田节肢动物种类及其优势度调查

【研究目的】为摸清龙岩烟区烟田节肢动物群落种类及其优势度和套种大蒜调控烟草害虫提供参考，【方法】作者于2008—2009年在龙岩市烟草公司烟科分所试验田进行了系统调查，并于2011—2017年采用随机调查的方法，调查烟株节肢动物群落情况与系统调查结果相互验证。【结果】2008—2009年结果表明：采集到节肢动物标本11501号，分别属于2纲11目44科65种。植食类节肢动物有33种植食类功能群物种，仅烟蚜为优势种；寄生类功能群物种9种，仅发现烟蚜茧蜂为常见种（2009年）或偶见种（2008年）；捕食类功能群物种16种；中性类功能群物种7种，仅发现稻摇蚊为优势种。【结论】通过系统调查与随机调查相结合，摸清了龙岩烟区的植物食类群、天敌害类群和中性类群及其优势种，这些调查结果对龙岩烟区烟草害虫的防治和害虫天敌、中性类节肢动物保护利用具有重要的意义。

Investigations on Arthropod and Their Dominance in Flue-cured Tobacco Field of Longyan

The purposes are to investigate the species of arthropod and their dominance in flue-cured tobacco field of Longyan, and to provide a basis for controlling tobacco pests by interplanting garlic. A systematic investigation was conducted in the experimental field of tobacco substation of Tobacco Company in Longyan City from 2008 to 2009. In 2011- 2017, the authors conducted a random investigation on the arthropod populations to verify the systematic investigation from 2008 to 2009. The results showed that 11501 individuals of arthropods were obtained, and they belonged to 2 classes, 11 orders, 44 families and 65 species. The herbivore functional group had 33 species, only Myzus persicue (Sulzer) was the dominant specie among them. There were 9 species belonging to parasitoid functional group, and only Aphidius gifuensis Ashmead was a frequent specie (2009) or occasional specie (2008). There were 16 species belonging to predator functional group. There were 7 species belonging to neutral functional group, and only Chironomus oryzae Mats. was the dominant specie. The results of the random investigation in 2011-2017 were consistent with the results of the systematic investigation in 2008-2009.
