摘    要:1998年5~7月对合肥郊区自然状态下Nc89、Nc82和K326烟草生产品种上重要节肢动物种群数量消长规律进行了系统研究.结果表明,烟田重要蜘蛛类天敌是皿蛛、狼蛛、球蛛、肖蛸蛛、蟹蛛、跳蛛和管巢蛛等,重要昆虫类天敌是烟蚜茧峰(Aphidiusgifuensis)、瓢虫、隐翅甲、步甲、大灰食蚜蝇(Syrphascoralae)和小花蝽(Oriusmiutus)等,重要害虫是烟蚜(Myzuspersicae)、烟青虫(Heliothisasulta)、斑须蝽(Dolycorisbacarum)和油葫芦(Grylustestaceus)等.烟蚜种群数量消长有两个明显的峰值,分别出现在5月16日和6月13~21日前后.文中对烟蚜种群数量动态模型,烟蚜和草间小黑蛛(Erigonidiumgraminicola)种群相互作用做了分析.烟蚜茧蜂种群平均数量Nc89烟草品种显著高于Nc82和K326,主要害虫个体总数平均数量Nc89品种显著高于K326,不同烟草品种上的其它节肢动物种群平均数量均无显著差异

关 键 词:烟草品种  节肢动物  种群数量动态

Abstract:Investigations on the population fluctuation patterns of important arthropods on three Nicotiana tabacum production varieties Nc89, Nc82 and K326 were conducted in the suburbs of Hefei from May to July, 1998. In the investigated tobacco fields, araneae taxa were Linyphiidae, Lycosodae, Theriodiidae, Tetragnathidae, Thomisidae, Salticidae and Clubionidae, etc.. The major insect natural enemies were Aphidius gifuensis, Coccinellidae, Staphylinidae, Carabidae, Syrphas corallae and Orius miutus , and the major insect pests were Myzus persicae, Heliothis assulta, Dolycoris baccarum and Gryllus testaceus. The aphid population fluctuation showed two peaks, with the first one around 16 May and the second one from 13 to 21 June. The models of aphid population dynamics and the interreaction between Myzus persicae and Erigonidium graminicola were analysed. The mean seasonal number of Aphidius gifuensis population, and hence, that of total insect pests, were significantly higher on Nc89 than on Nc82 and K326. There was no significant difference in the mean seasonal number of other arthropods on different tobacco varieties.
Keywords:Tobacco variety      Arthropod  Population dynamics
