Abstract:Rice crops are constantly damaged by a variety
of pests during cultivation, which greatly affects human food security.
Metabonomic data can not only reflect internal physiological and biochemical
changes in cells or organisms, but also indicate how these are affected by
different factors. This paper reviews progress in research on the metabolomes
of rice pests, introduces the main methods used in metabolomics, i.e., nuclear magnetic resonance technology and mass spectrometry
chromatography coupling technology, and summarizes the application of metabolomics to rice pest research, including that on
pesticide resistance, insect-rice interactions and insect-symbiotic bacteria
interactions. The shortcomings of metabolomics in terms of accuracy, sensitivity and resolution are also discussed, as
well as prospects for using metabolomics and other combined multi-omics
techniques to find novel insecticidal targets, develop new
biological pesticides and transgenic resistant rice plants, and other
environmentally-friendly methods for the prevention and control of rice pests.
