| 中文摘要: |
| 为提高实蝇粘虫板对桔小实蝇的诱杀效果，减少对天敌的诱杀，为科学悬挂实蝇粘虫板提供参考依据。采用4种悬挂方式，分别为悬挂于树冠中部胶面与地面垂直、悬挂于树冠中下部胶面朝下、悬挂于树冠中下部胶面朝上、悬挂于树冠上部胶面朝上，调查实蝇粘虫板上桔小实蝇、其它害虫和天敌的种类和数量。结果表明，4种悬挂处理的实蝇粘虫板共诱杀到20个昆虫种或类群，其中悬挂于树冠中部胶面与地面垂直的实蝇粘虫板诱杀昆虫种类、多样性指数最高，而悬挂于树冠中下部胶面朝上的实蝇粘虫板的益害比最高；悬挂于树冠中部胶面与地面垂直、树冠中下部胶面朝下的实蝇粘虫板对桔小实蝇的诱杀数量显著高于其它2种悬挂方式的实蝇粘虫板（p<0.05）；悬挂于树冠中下部胶面朝上和树冠上部胶面朝上的实蝇粘虫板均对食蚜蝇具有较强的诱杀作用。因此，采用树冠中部胶面与地面垂直、树冠中下部胶面朝下的悬挂方式均可以作为田间应用实蝇粘虫板的方法；但采用树冠中下部与地面平行朝下的悬挂方式更有利于天敌的保护。 |

| To improve the trapping effect of sticky traps on Bactrocera dorsalis, and reduce the trapping to natural enemy, in order to provide reference bases for hanging the sticky traps scientifically. We set fruit fly sticky traps with 4 suspension mode, that the side of viscose is vertical to the ground in the middle part of the canopy, parallel to the ground downwards in the lower part of the canopy, parallel to the ground upwards in the lower part of the canopy, and parallel to the ground upwards in the upper parts of the canopy respectively, the species and quantity of Bactrocera dorsalis, other pests and natural enemy were surveyed on different fruit fly sticky traps. The result show that 20 insect species were lured in 4 treatment, of that the trapping species, natural enemy and diversity index were highest by vertical to the ground in the middle part of the canopy, the predator/prey ratio was highest by parallel to the ground upwards in the lower part of the canopy; the trapping number of fruit fly sticky traps hanged by vertical to the ground in the middle part of the canopy and parallel to the ground downwards in the lower part of the canopy were significantly higher than it hanged by parallel to the ground upwards in the lower part of the canopy and parallel to the ground upwards in the upper parts of the canopy (p<0.05); it had a good attract effect to syrphids by parallel to the ground upwards in the lower part of the canopy and parallel to the ground upwards in the upper parts of the canopy. Therefore, the best suspension mode to fruit fly sticky traps on field were hanged by vertical to the ground in the middle part of the canopy and parallel to the ground downwards in the lower part of the canopy; but it was better for natural enemies to adopt the suspension mode as hanged by parallel to the ground downwards in the lower part of the canopy. |
