Abstract:

For use of biodiversity control insects and screening of tea varieties to insects carry the basis,in the six tea varieties as test materials, a parallel method of different tea varieties breed jumping arthropod community composition differences. It show that the each tea varieties of the arthropod community composition, diversity is similarities, but the main predators and pests of tea, the dynamic trend of diversity, different levels of arthropod groups were different. The ratio of the maximum number of individuals and their communities’ pest predators was ‘Lechangdayebaimao’, the arthropod of diversity index and dominance index average larger was ‘Yundadanlu’, the arthropod of more diversity and richness of tea plexus upper. Tea plexus different levels arthropods diversity was differences. ‘Yundadanlu’ and ‘YingHong10’ were plexus upper species more; in the tea plexus below, arthropod species diversity index is up on ‘Biyun’.
