| 摘 要： | 梨树矢尖蚧(Unaspis sp．)是在我省龙里林场梨园内新近发现的重要虫害之一,分别使用融杀蚧螨 (C20H2902Na)150倍液,200倍液和250倍液进行防治,并同时防治三楂叶螨(Tetranychus viennensis),结果发现融杀蚧螨对梨树矢尖蚧的防治效果优于对三楂叶螨的防治效果,且不同浓度处理间防治梨树矢尖蚧效果差异极显著。特别是150倍液的融杀蚧螨对梨树矢尖蚧具有较好的杀灭效果。

| Abstract: | A new pest was found in pear orchard of Longli Forest Farm in Guizhou, and it was primarily identified as Unaspis sp. Control of this pest by sodium rosin acid with different concentrations ( 1: 150, 1:200, 1:250) was studied in this paper. The result showed that the controlling effect of sodium rosin acid on Unaspis sp. was higher than that on Tetranychus viennensis, and the different concentration had significantly different effect, with the concentration of 1:150 had the best effect on Unaspis sp. |
