不同诱捕器对烤烟斜纹夜蛾的诱捕和防治效果对比研究

Research on Trapping and Control Effects of Different Traps with Sex Pheromone on Spodoptera litura Fabricius of Fluecured Tobacco

通过田间试验,分析了斜纹夜蛾在烤烟田间发生的时间动态,比较了不同诱捕器对烤烟斜纹夜蛾的诱捕效果。结果表明:斜纹夜蛾在当地烤烟生长期内有2次迁飞高峰期,分别在4月下旬和6月下旬,即烤烟进入成熟期和采烤期之后;诱蛾量和田间虫情指数统计表明,2种诱捕器均对防治斜纹夜蛾有极显著的效果,且诱捕器2的效果好于诱捕器1。

Through the field experiment,the temporal dynamics of Spodoptera litura occurring to flue-cured tobacco were analyzed,and the trapping effects of different traps with sex pheromone were compared.The results showed that two migration peaks of Spodoptera litura occurred in late April and late June of flue-cured tobacco growing periods ,respectively ,when the mature period and baking period were coming. The statistics of the trapping quantities and insect pest situation index showed that both types of traps had highly significant effects on controlling Spodoptera litura, ancl the effect of trap 2 was better than that of trap 1.
