摘　　要：为明确不同生长期烤烟蓟马种类及其发生规律,对昆明烤烟苗期叶片、大田期叶片和烟花上的蓟马种类进行了调查,同时对不同生长期烤烟蓟马的危害规律进行了系统研究。结果表明:为害昆明烤烟的蓟马有1科、2属、7种,其中西花蓟马是烤烟整个生长期的优势种类,占采集蓟马总数的57.05%;苗期随着蓟马对烤烟的为害株率的逐步升高,番茄斑萎病毒病病株率和危害程度也明显提高,表现出明显的正相关;而大田期则没有表现出关联性。蓟马主要为害烤烟的苗期和开花期,而开花期烤烟已打顶抹杈,因此应将苗期蓟马的防治作为烤烟生产上蓟马防治的重要环节。In order to clarify thrips species and occurrence at different growth stages of flue-cured tobacco, thrips species on leaves at seedling and field growth stages and flowers at field growth stages were investigated in Kunming. Thrips damage rules at different growth stages were also studied. The results showed that there were seven thrips species causing damages to flue-cured tobacco in Kunming, belonging to two genera of a single family. The dominant species was Frankliniella occidentalis at the entire growth stages of flue-cured tobacco,accounted for 57.05% of the total thrip number. At seedling stage, with the increase of flue-cured tobacco plants injured by thrips, the proportion and damage degree by tomato spotted wilt virus(TSWV) clearly increased, and presenting a significant positive correlation. However, there was no correlation at field growth stages. Thrips occurred most seriously at seedling and flowering stages of flue-cured tobacco. For topped flue-cured tobacco,therefore seedling stage was the critical time for thrips control.
