摘要 为研究烟草—荞麦间作对烟田害虫及天敌发生的影响,为烟草害虫的绿色防控提供科学依据,在2020—2021年对烟草—荞麦间作烟田害虫和天敌种类与数量进行了系统调查,并对害虫和天敌的发生动态及生态位进行分析。结果表明,烟草—荞麦间作下,烟田害虫种类和数量降低,天敌种类及数量增加。同时,在害虫爆发期吸引了更多的天敌。此外,时间生态位指数分析表明,烟草—荞麦间作模式提高了天敌与害虫的追随时间。本研究结果表明烟草—荞麦间作可影响烟田害虫和天敌的发生,对于烟草害虫的绿色防控具有指导作用。 This paper studied the effects of tobacco-buckwheat intercropping on the occurrence of pests and natural enemies in tobacco fields,aiming to provide scientific basis for the eco-friendly control of tobacco pests.The paper investigated systematically the species and numbers of pests and natural enemies in tobacco fields under tobacco-buckwheat intercropping from 2020 to 2021,and analyzed the occurrence dynamics and niche of pests and natural enemies.The results showed that under tobacco-buckwheat intercropping,the species and numbers of pests decreased while the spe-cies and numbers of natural enemies increased.Meanwhile,more natural enemies were attracted dur-ing pest outbreaks.In addition,analysis on the temporal niche index showed that under the tobacco buckwheat intercropping model,the tracking time of natural enemies and pests was increased.The results of this study indicated that tobacco-buckwheat intercropping could affect the occurrence of pests and natural enemies in tobacco fields,which provided an important reference on the green pre-vention and control of tobacco pests.
