Abstract:

To effectively monitor the occurrence and damage of dangerous pests in Zhaoshu Island, a systematic survey and risk assessment on all the pests of 90 plants in Zhaoshu Island was conducted. The results showed that there were 19 insects and mintes of 8 wild halophytes including 5 alien invasive pests and 7 world dangerous pests occurred and harmed seriously; 24 insects and mintes of 29 landscape plants including 9 alien invasive pests and 6 world dangerous pests occurred and harmed seriously; 36 insects and mintes of 31 salt-tolerant fruits and vegetables including 7 alien invasive pests and 6 world dangerous pests occurred and harmed seriously; 16 insects and mintes of 22 sand-bander plants including 5 alien invasive pests and 2 world dangerous pests occurred and harmed seriously. The results of risk assessment showed that Brontispa longissima, Paracoccus marginatus, Phenacoccus solenopsis and Opisina arenosella were all high-risk pests in Zhaoshu Island with R value 2.12, 2.12, 2.09 and 2.02, while Dysmicoccu neobrevipes, Diaspis boisduvalii, Tetranychus urticae, Thrips palmi, Bemisia tabaci, Liriomyza sativae and Bactrocera cucuribita were all moderate risk pests in Zhaoshu Island with R value 1.92, 1.89, 1.82, 1.79, 1.79, 1.74 and 1.61, respectively.
