陇西黄芪蚜虫的生态学特性及防治方法研究

Review on ecological characteristics and control of Aphid gosypii host Astragalus membranaceus in Longxi

蚜虫生物学和种群生态学研究是开展蚜虫防治的基础,对于探讨其他理论问题也很重要。蚜虫生物学指其生活习性包括生活史、种群变化、生理等,与气候、环境因子等的关系则构成了蚜虫生态学研究内容。本文阐述了危害陇西黄芪的主要蚜虫槐蚜(Aphis robiniae Mcachiat)、苜蓿蚜(Aphis craccivora)和豌豆蚜(Acyrthosiphon pisum)的形态学特征、种群生态学特征及具有针对的防治方法,了解陇西“道地”黄芪蚜虫种群的空间分布动态、蚜虫的繁殖策略及迁飞,这对提高测报准确性和开发防治新方法有重要意义。

The review on biological characteristics and ecology population of Aphid gosypii is the basis its control,and it is also important to explore other theoretical issues.Aphid Biological characteristics refers to its life habits,including life history,population changes,physiology,and climate,environmental factors and other relationships constitute research content of aphid ecology.This paper describes the characteristics of morphological and ecology population and targeted control methods of Aphis robiniae Mcachiat,Aphis craccivora and Acyrthosiphon pisum,which are the main pests in the Astragalus membranaceus in Longxi.The study of the spatial distribution dynamics,reproductive strategy and migration of population of Aphid gosypii from host Astragalus membranaceus in Longxi,It is of great significance to improve the accuracy of prediction and to develop new methods for prevention and control.
