为了探索梨瘿蚊无害化的防治方法,本文连续2年开展了黄色、蓝色、深蓝色、白色、绿色、紫色、灰色、黑色和粉红色9 种不同颜色的色板对梨瘿蚊的诱集效果的比较,同时探索了黄板在田间的使用方法。通过连续2年的调查结果表明,梨瘿蚊对黄色色板趋性最大,与其它8种颜色色板之间存在极显著差异(P<0.05)。当黄色色板的悬挂高度分别为0.5m、1.0m、1.5m 和 2.0m时,以不高于1.5m 的诱杀效果为最佳(P<0.05);间距分别为 2 m、3 m、4 m 、5 m 和6m时,以4m间距的诱虫量最多,但是不同间距之间的诱虫量在(P<0.05)的水平上差异不显著。诱虫板设在树体的不同方位之间诱虫量的差异不显著(P<0.05) |

To explore the method harmless controlling means of Dasyneura pyri ,the attractiveness to Dasyneura pyri of 9 types of colored sticky cards: yellow,blue,navy blue,white,red,green,purple,gray and pink,were investigated at pear orchards in 2 years. And the usage of yellow trap was explore in this paper.The result show that Dasyneura pyri significantly preferred yellow cards to the other eight colors (P<0.05). Significantly more Dasyneura pyri were trapped by cards placed at under 1.5m above ground level( P < 0. 05). There is no significantly diffence between cards spaced at intervals 2 m、3 m、4 m、5 m and 6m,but the more Dasyneura pyri were trapped on cards spaced at 4m(P<0.05). And no significant difference in the number of Dasyneura pyri trapped at different direction of pear tree are existed(P<0.05). |
