Abstract:

Natural enemies are an important kind of agricultural germplasm resources. It is necessary to clarify the basic situations of natural enemies through nationwide systematic surveys, and preserve then using appropriate methods. The basic long-term scientific and technological work of the Ministry of Agriculture and Rural Affairs aims to carry out scientific observation and monitoring of various elements in agricultural production, to establish a network of agricultural scientific observation work, to analyze interrelationships of various elements in complex agricultural systems, and to summarize scientific laws. The work was launched in 2017, with 10 subject area centers established, including the National Data Center of Insect Natural Enemies and Edible Insect Resources (hereinafter referred to as "Natural Enemy Center"). Over the past five years, the Natural Enemy Center has organized more than 100 experimental sites to carry out natural enemy resource surveys continuously, and have collected a large amount of data and specimens. This paper introduces the main survey and conservation methods used in the work of the Natural Enemy Center. At present, natural enemy resources survey mainly adopts a combination of manual survey and Malaise trap insect collection. For collected descriptive and picture information, a "collection-entry-review-conservation" process and a database have been established. A specimen library has been established correspondingly. In addition, the concept of “in situ conservation of natural enemy resources” is strongly recommended. The opportunities and challenges faced by the natural enemy resources survey, relying on the basic and long-term scientific and technological work, were also discussed. The significance of establishing a future direction of combining "internal strengthening" and "external supporting" is emphasized. On the one hand, we should actively seek for policy and project support within the system to build a solid foundation for the work; on the other hand, we should vigorously promote the work to the society and widely carry out "citizen science" as a support. Only in this way, the long-term operation of this work will be ensured. The data will always have a comprehensive coverage, and data accumulation will increase steadily.

Key words: species resources, genetic resources, Malaise trap, in situ conservation, citizen science
