Research Progress of Aphids Information Monitoring
Cotton is an important strategic material and one of our important economic crops.It plays an important role in our agricultural pro-duction,people's livelihood and secondary and tertiary industries.Cotton aphid is one of the major pests in the process of cotton growth and development.The lag and inaccuracy of aphid information will lead to the excessive application of pesticides,which will accelerate the destruc-tion of cotton habitat and the pollution of cotton field environment.Therefore,it is of great practical significance to obtain the temporal and spa-tial distribution,hazard level and occurrence area of aphids in cotton fields in real time and accurately for the prevention and control of cotton aphid,cotton field management and farmland environmental protection.Remote sensing technology and machine vision technology speed up the acquisition of real-time and dynamic information and classification of aphids in cotton fields.This paper focused on"cotton aphid situation in-formation monitoring",carried out literature review and combing at home and abroad,and described the research status and progress of tradi-tional methods,remote sensing technology and image recognition on cotton aphid situation information.The problems in the monitoring of cotton aphid were discussed,and the research focus and development trend of the monitoring and diagnosis of cotton aphid damage information in the future were prospected.
