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。
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.
