Adaptability and 'Candidatus Liberibacter asiaticus' titres of Diaphorina citri adults on three weed species in China.

D. citri exhibited different adaptabilities to the three weed species, but the CLas titres of D. citri adults did not decrease on any of the weeds. These results suggested that the three weed species could help dispersing of D. citri and transmission of CLas while ideal host conditions were scarce or absent. © 2021 Society of Chemical Industry.
