Objective To explore the occurrence of weeds and Frankliniella intonsa in the field of Datong daylily,and to pro-vide evidence for comprehensive coordinated prevention and control strategies.Methods The species of weeds and the occurrence of Frankliniella intonsa adults were investigated in the field of Datong daylily.Results 38 species of weeds in 31 genera of 11 fami-lies were found,including 23 species of annual plants in 20 genera of 7 families,16 species of perennial plants in 13 genera of 6 fam-ilies.There are 6 species of alien invasive species in 5 genera of 4 families in 38 species of weeds.The relative abundance analysis showed that Teloxys aristata(L.)Moq.of Amaranthaceae,Setaria viridis(L.)P.Beauv.of Poaceae and Tribulus terrestris L.of Zy-gophyllaceae were the dominant species of weeds in the field of Datong daylily.Amaranthus lividus L.,Panicum miliaceum L.,Che-nopodium album L.,Convolvulus arvensis L.,Salsola collina Pall.,Ambrosia artemisiifolia L.,Schoenoplectiella wallichii(Nees)Lye and Artemisia annua L.are the common weeds,among which Amaranthus lividus L.and Ambrosia artemisiifolia L.are alien in-vasive species.The occurrence of Frankliniella intonsa adults in Datong daylily plots with or without weeds was compared,which showed that the growth of weeds could reduce the occurrence of Frankliniella intonsa adults.Conclusion There are 38 species of weeds in the field of Datong daylily,including 3 dominant species and 8 common species.The existence of weeds in a specific peri-od has certain inhibition on the occurrence of Frankliniella intonsa adults.
