摘 要: | [目的]了解晚熟桃园梨小食心虫越虫茧的空间分布情况。[方法]以中华寿桃、北京晚蜜和黄金冬桃为试材,研究了晚熟桃园梨小食心虫越冬茧的空间分布情况。[结果]越冬茧主要分布在桃树的地上部,土壤及地表枯枝中较少,残果、芽、落叶和杂草内未发现越冬茧;各部位的梨小食心虫越冬茧比例分别为:地上部占越冬茧总量的89.62%,土壤中占10.31%,地表枯枝中占0.69%。[结论]为梨小食心虫越冬代的防治提供了理论依据。

Abstract: | [Objective] The aim was to understand spatial distribution of hibernating cocoon of oriental fruit moth in late-maturing peach orchard.[Method] The spatial distribution of hibernating cocoon of oriental fruit moth in late-maturing peach orchard was studied with peach germplasm ‘ Zhonghuashoutao’,‘ Beijingwanmi’ and ‘ Huangjindongtao’ as experimental materials.[Result] The hibernating cocoon was mainly distributed in the peach tree,less in surface soil and ground dead-branch,and it was not found in residual fruit,bud,defoliation and litter layer.The proportion of each part was peach tree 89.62%,surface soil 10.31%,and ground dead-branch 0.69%.[Conclusion] The research result provides theoretical basis for the control of hibernating cocoon of oriental fruit moth. |
