Abstract: Thrips are important pests of agricultural and horticultural crops, causing enormous economic losses by direct feeding and indirect transmission of the plant-pathogenic virus. Plant secondary metabolites play a pivotal role in plant-insect interactions. The manipulation of insect behavior using plant secondary metabolites to protect crop plants from pest infestation is a promising eco-friendly control tactic. In this article, plants, plant extracts, essential oils and chemical compounds that have attractive, repellent, oviposition and feeding deterrent effects, fumigation toxicity and toxic activities to thrips were reviewed, and the potential of plant secondary metabolites for thrips management was discussed. Volatiles or essential oils from 54 plant species in 27 families, 29 benzenoids, 17 pyridines and 13 terpenes are attractive to thrips and could be used as trap plants and attractants. Volatiles or essential oils from 40 plant species in 17 families, 20 terpenes and 6 benzenoids show repellency against thrips and could be used as repellent plants and repellents. Extracts or essential oils from 42 plant species in 20 families, 6 alkaloids, 15 terpenes and 5 benzenoids have oviposition and feeding deterrent effects, fumigation toxicity and toxic activities to thrips, and could be developed into botanical pesticides and fumigants. Finally, current problems of plant secondary metabolites in thrips management, such as unstable effects, lack of field application technology and unclear muchamisms, were discussed, and potential research directions were prospected, which are of great significance to thrips management based on plant secondary metabolites.

Key words: Thrips, plant secondary metabolites, attractive effects, repellent effects; oviposition deterrent effects, feeding deterrent effects, fumigation toxicity, toxic activity, biocontrol
