摘要
针对冀西北仁用杏蚧壳虫发生面积大 ,危害严重的生产问题 ,研究了仁用杏蚧壳虫类的区系分布、生物学特性、发生消长规律、防治方法等 ,初步探明了在冀西北仁用杏主产区蚧壳虫的发生与分布、生活史中的薄弱环节 ;通过大量的田间试验和大面积生产示范 ,总结出一套以人工和农业防治为主 ,化学防治为辅的综合防治措施。
The study on area distribution of kernel use apricot scale insect,biological character,growth and decline regularities,ways of prevention and control was carried out.The appearance and distribution of scale insects and the weak link in their life history in main kernel use apricot production area of northwest of Hebei province were ascertained.A set of comprehensive prevention and control measures which take artificial and agricultural prevention as the most important way and chemical control as auxiliary way was summarized by many field experiments and large area demonstrations.
