摘　　要：为明确瓦楞纸板诱虫带对梨园越冬害虫与天敌的诱集效果,探究了瓦楞纸板类型对诱集效果的影响,并比较了该诱虫带对同一品种不同绑扎部位、相同品种不同树形以及不同品种梨树越冬害虫与天敌的诱集效果。试验结果表明,不同宽度瓦楞纸诱虫带对害虫的诱集效果无显著差异。瓦楞纸诱虫带不同绑扎部位对天敌诱集效果无显著影响,但将其扎绑至距离梨树第一分枝处10~20 cm处时,对梨木虱诱集效果最佳。不同品种梨树间瓦楞纸诱虫带诱集到天敌的数量差异较小,‘雪花’梨树上诱集到的梨木虱数量显著多于‘南果’梨。不同树形间诱集结果显示,Y字形与纺锤形梨树的瓦楞纸板诱虫带内梨木虱诱集量多于倒伞形梨树诱虫带内诱集量,但不同树形梨树上瓦楞纸诱虫带内天敌的诱集数量并无显著差异。试验结果为瓦楞纸在果树害虫防治和天敌保护中的应用提供理论指导。In order to clarify the trapping effect of corrugated paper traps on overwintering pests and natural enemies,the effects of corrugated board types were investigated,and the trapping effects on different wintering pests and natural enemies at different banding locations of the same variety,on different tree types and on different varieties of pear trees were compared as well.The results showed that there was no significant difference in the trapping effects by corrugated insect traps of different widths.Corrugated cardboard at different banding locations had no significant difference in trapping effect on natural enemies,but when it was tied to the distance of 10-20 cm from the first branch of the pear tree,it had the best trapping effect on Psylla chinensis.The difference in the number of natural enemies trapped in corrugated paper traps between different varieties of pear trees was small,while the number of P.chinensis trapped by‘Xuehua’was significantly higher than that of‘Nanguo’.The trapping results between different tree types showed that the number of P.chinensis trapped in the corrugated paper traps of the Y-shaped and spindle pear trees was higher than that in the inverted umbrella traps,but no significant difference in the trapped number of natural enemies.The results provide theoretical guidance for the application of corrugated paper in fruit tree pest control and natural enemy protection.
