Abstract:

To clarify the pests that may be carried by Actinidia chinensis seedlings and their invasion risks, and to provide a reference for the introduction of A. chinensis seedlings from Japan, the pest information regarding A. chinensiswas searched through the national biosafety basic data information resource platform. The regional distribution of key quarantine pests in the world was clarified through the databases of EPPO, CABI and GBIF, and the risk of invasion was analyzed by the previous relevant studies. The results showed that the pests on A. chinensis plants included 18 species of insects, 4 species of nematodes, 1 species of mite, 1 species of weed, 1 species of mollusk, 24 species of fungi, and 5 species of bacteria. Among these, 5 species belonged to the Chinese imported phytosanitary pests, namely, Lobesia botrana, Involvulus cupreus, Radopholus similis, Euglandina rosea, and Verticillium albo-atrum, with hazardous R-values of 2.14, 2.46, 2.70, 2.51 and 2.52, respectively, belonging to the highly or particularly hazardous pests. To ensure a successful introduction of plant seedlings, it is crucial to collaborate with both internal and external inspection teams to quarantine any potential pests. Adhering to strict quarantine standards and the transmission of pests must be prevented. Once the seedlings are introduced, it's essential to enhance trial planting supervision and improve the pest monitoring system.
