Abstract

Potential distribution of Sminthurus viridis in China analyzed by BIOCLIM model.

Abstract

DIVA-GIS software combined with BIOCLIM ecological niche model was used to predict the habitat of Sminthurus viridis in China. The potential distribution of S. viridis in China was mapped by establishing a dataset of distributed points, screening for major influences and BIOCLIM model prediction. The results showed that S. viridis could colonize the entire North China Plain, the southern part of the Northeast Plain, the Yunnan-Guizhou-Sichuan region in the southwest, and the northern part of South China. The highly habituated areas were in the middle and lower reaches of the Yangtze River and the Yellow River, involving six provinces, i.e. Sichuan, Gansu, Ningxia, Shaanxi, Hubei and Anhui. In view of the high risk of invasion of S. viridis, the inspection and quarantine of this pest should be strengthened, especially vigilant against its entry into China with imported grain.
