英文摘要	通过设置5种类型烟田,研究了栽培措施对烟田前期烟蚜Myzus persicae(Sulzer)和烟蚜茧蜂Aphidius gifuehsis(Ashmead)种群数量的影响.地膜和耕作方式对烟田前期烟蚜种群数量均有显著影响.不同类型烟田烟蚜种群数量大小依次为桃园附近、纯作未覆膜、间作未覆膜、纯作覆膜、间作覆膜烟田.其中,桃园附近烟田烟蚜种群数量显著高于其它烟田,未覆膜烟田高于覆膜烟田,纯作烟田又高于间作烟田.地膜对烟田前期烟蚜茧蜂种群数量有显著影响.覆膜烟田烟蚜茧蜂种群数量高于未覆膜烟田.因此,烟田覆膜有利于降低烟蚜种群数量、增大烟蚜茧蜂种群数量;间作也能在一定程度上抑制烟蚜种群增长.; Influence of cultural practices on the population size of Myzus persicae (Sulzer) and Aphidius gifuehsis (Ashmead) in the early growth season was investigated in 5 types of tobacco fields. Plastic film mulch and cropping pattern both exhibited significant influence on the population size of M. persicae in the early season. Tobacco field near peach orchard was infected with significantly higher aphid population (4 220 ± 747.9 /100 plants) than the other four types of fields; namely, simple cropped & un-mulched (2116.0 ± 880.7 /100 plants) , intercropped & un-mulched (880.0 ± 244.0 /100 plants), simple cropped & mulched (696 .0 ± 328 .8/100 plants) , intercropped & mulched (408.0 ± 198.3 /100 plants) fields. Film mulch also significantly affected die population size of A . gifuehsis in the early season. Wasp population was higher in film-mulched fields (104.0 ±62.3 /100 plants and 64. 0 ± 38.5 /100 plants for simple cropping and intercropping, respectively) than in un-mulched fields (32.0 ± 26. 8 /100 plants and 32.0 ± 17.9 /100 plants for simple cropping and intercropping, respectively). Therefore, film mulch is effective in both decreasing population of M. persicae and increasing population of A. gifuehsis. Intercropping is also effective in checking population of M. persicae.
