Prediction of the potential geographical distribution of European grapevine month Lobesia botrana in China considering the irrigation and climate conditions
European grapevine moth,Lobesia botrana(Denis & Schiffermuller,1775)(Lepidoptera:Tortricidae) has been listed as the quarantine pest and currently absent in China.To clarify the potential geographical distribution of L.botrana in China,according to its latest known distribution occurrence,CLIMEX 4.0.2 was used to predict the potential geographical distribution of this pest under current and future climate conditions considering irrigation scenario.The results showed a wide potential geographical distribution of the pest throughout China,including all the current grape growing areas.With the climate change,in 2030,the potential range of the pest in China would increase in Heilongjiang,Qinghai and Sichuan,with an overall increase in the suitable level.Therefore,quarantine measures should be strengthened in order to prevent its introduction and protect the grape industry in China.
