Zhao Xueyuan and so on (1979) (Diaphorina citri) may disseminate the Huanglong sickness through the experimental confirmation citrus fruits aphid, through the investigation discovered Huanglong gets sick the popular region is roughly consistent with the citrus fruits aphid's distribution. in 1987, Zhou Qiming proposed for the first time the citrus fruits aphid in Guangxi domestic the question which migrates by sweet osmanthus southing Gui Bei.
