Abstract: In this study, we investigated species and residence time of flower-visiting insects on six different flowering plant species in a tea garden by catching with a net and observation. We analyzed the dominant species of visiting insects and their activities on different flowering plant species. The results showed that there were 31 species of flowervisiting insects belonging to 25 families and seven orders, 12 species belonging to 10 families and five orders on Begonia grandis and Begonia semperflorens, respectively. Both Monolepta hieroglyphica and Apolygus lucorum were the dominant species on these two plant species. There were 21 species of flower-visiting insects belonging to 16 families and six orders on Salvia japonica, with the dominant species being Cletus trigonus. There were 34 species of flower-visiting insects belonging to 26 families and seven orders on Euryops pectinatus, with the dominant species being Bacch maculata, Xenocatantops brachycerus, and Dolichopus meridionalis. There were 39 species of flower-visiting insects belonging to 32 families and eight orders on Impatiens balsamina, with dominant species being Crematogaster rogenhoferi. There were 21 species of flower-visiting insects belonging to 18 families and 7 orders on Digitalis purpurea, and the dominant species were Bombus breviceps and D. meridionalis.A. lucorum and D. meridionalis had the longest residence time on D. purpurea, with residence time of 55.33 and 25.12 s·min^-1, respectively. C. trigonus had the longest residence time of 57.50s·min^-1 on E. pectinatus.C. rogenhoferi had the longest residence time of 13.47 s·min^-1 onI. balsamina.B. maculatehad the longest residence time of 58.33 s·min^-1 on B. semperflorens. X. brachycerus had the longest residence time of 58.26 s·min^-1 on B. grandis. The two dominant predators, B. maculata and D. meridionalis, had the highest proportion (22.41% and 13.32%, respectively) and frequency (3.60 times and 2.13 times, respectively) of visiting flowers on E. pectinatus. E. pectinatus attracted most species of natural enemy, with longer stay of the dominant natural enemy species than on other plant species. Therefore, we should increase the abundance of flowering plants that can attract more diversity of natural enemies to promote the role of natural pest control in tea gardens.
