Abstract:

Tobacco virus disease (tobacco mosaic virus, cucumber mosaic virus, potato virus Y, etc.) is one of the most common tobacco diseases in the world, which often causes great loss in tobacco production. In order to understand the spatial distribution of tobacco virus disease in field, this paper analyzed the ecological niche characteristics of virus disease pathogens through field systematic investigation. The results show that the host ecological niche breadth of tobacco virus disease is large in Longyan tobacco planting area. With the growth of tobacco, the ecological niche breadth of tobacco virus disease gradually increases, and the value in the later growth stage is close to 0.9, indicating that the virus disease could infect most of the tobacco in the area. At the same time, the ecological niche breadth of the incidence of cucumber mosaic virus disease is 0.94, and that of common mosaic virus disease is 0.8256, indicating that the spread rate of cucumber mosaic disease is faster than that of common mosaic disease. The research on the ecological niche of infectious diseases could provide a basis for the effective ecological regulation of diseases.

Key words: Longyan, tobacco, tobacco virus disease, ecological niche breadth
