| 明确修文县猕猴桃桑盾蚧的发生规律与空间分布，为控制桑盾蚧的危害提供依据。以修文县“贵长”猕猴桃为试材，采用定点定株方法掌握桑盾蚧在修文县的发生规律，平行跳跃方法调查猕猴桃园桑盾蚧分布，随机取样与五点取样相结合方法调查桑盾蚧在猕猴桃树上不同方位的分布。桑盾蚧在修文“贵长”猕猴桃园中一年发生两代，以受精雌成虫在枝条上越冬，5月上旬和8月上旬为产卵盛期，桑盾蚧对“贵长”猕猴桃树的方位侵害程度表现为：南＞东＞北＞西，其危害对猕猴桃树上的方位有一定的选择性。 |
| 英文摘要: |
| In order to control the damage of Pseudaulacaspis pentagona , the occurrence regularity and spatial distribution of Pseudaulacaspis pentagona in Xiuwen County were clarified.Taking the kiwifruit "Guichang" in Xiuwen County as the test material, the occurrence rule of Pseudaulacaspis pentagona in Xiuwen County was mastered by the method of fixed-point planting, the distribution of in kiwifruit garden Pseudaulacaspis pentagona was investigated by the method of parallel jumping, and the distribution of Pseudaulacaspis pentagona in different directions on Kiwifruit tree was investigated by the method of random sampling and five-point sampling. In Xiuwen "Guichang" kiwifruit garden, the Pseudaulacaspis pentagona has two generations a year. It overwinters on the branches of the fertilized female adults. In the first ten days of May and the first ten days of August, it lays eggs. The damage degree of Pseudaulacaspis pentagona to the orientation of "Guichang" kiwifruit tree is: South > East > North > West. Its harm has certain selectivity to the orientation of the kiwifruit tree. |
