桑盾蚧在陇南市核桃上的发生及防治
|
摘要
对桑盾蚧(Pseudaulacaspis pentagona)在陇南市核桃上的为害情况、发生规律进行了观察研究,并在防治试验的基础上提出了综合防治措施。桑盾蚧在陇南1年发生2代,以受精雌成虫在寄主枝干上越冬,第2年5月中下旬和8月上旬进入卵孵化盛期,为药剂防治的关键时期,采取植物检疫、农业防治、人工防治、化学防治、生物防治等综合防治措施,可有效控制桑盾蚧的发生为害。
The damage and occurrence of Pseudaulacaspis pentagona on walnuts in Longnan City were observed and studied, and comprehensive control measures were put forward on the basis of control experiments. Two generations of P. pentagona occurred each year in Longnan. Fertilized female adults overwintered on host branches. In the second year, mid-late May and early August entered the peak period of egg hatching,which was the key period of pesticide control. Comprehensive control measures, such as plant quarantine, agricultural control, artificial control,chemical control and biological control,could effectively control the occurrence and damage of P. pentagona.
