Abstract:

The meanings of biodiversity and agro-biodiversity were reviewed. Pests control of agro-biodiversity was reviewed by genetic diversity, species diversity and landscape diversity.. Tobacco pests were controlled by species diversity on both temporal scales (relay cropping and rotation cropping) and spatial scales (intercropping) at present. Tobacco pests control by genetic diversity and landscape diversity of tobacco could be studied in future. The effects of weed control on different agro- biodiversity scales can be researched.
