龙岩烟区烟田节肢动物种类及其优势度调查

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

旨在摸清龙岩烟区烟田节肢动物群落种类及其优势度,并为套种大蒜调控烟草害虫提供参考,笔者于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。结果表明:2008—2009年采集到节肢动物标本11501号,分别属于2纲11目44科65种。植食类功能群物种有33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。并经2011—2017年随机调查验证发现,在大田情况与系统调查结果相一致。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、天敌类群和中性类群及其优势种。

The purposes are to investigate the species of arthropod and their dominance in flue-cured tobaccofield of Longyan, and to provide a basis for controlling tobacco pests by interplanting garlic. A systematicinvestigation was conducted in the experimental field of tobacco substation of Tobacco Company in LongyanCity from 2008 to 2009. In 2011-2017, the authors conducted a random investigation on the arthropodpopulations to verify the systematic investigation from 2008 to 2009. The results showed that 11501 individualsof arthropods were obtained, and they belonged to 2 classes, 11 orders, 44 families and 65 species. Theherbivore 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 functionalgroup. There were 7 species belonging to neutral functional group, and only Chironomus oryzae Mats. was thedominant specie. The results of the random investigation in 2011-2017 were consistent with the results of thesystematic investigation in 2008-2009.
