Analysis on the Species Diversity of Arthropod Communities in Different Tea Gardens

PurposeIn order to provide scientific basis for comprehensive management tea garden pests.

MethodThe diversity and stability of arthropod community in 2015 and 2016 of Baihaozao and Wuniuzao tea gardens were studied by using the community characteristic parameters and grey correlation degree method.

ResultAccording to comparison of the diversity indices obtained from 16-17 survey per year, there was no significant difference in the diversity of arthropod communities between Wuniuzao and Baihaozao tea gardens in 2015 (P>0.05), and the community diversity in Baihaozao tea garden was slightly higher than in Wuniuzao tea garden . There was extremely significant difference in community diversity between Wuniuzao tea garden and Baihaozao tea garden in 2016 (P<0.01), and the community diversity in Baihaozao tea garden was higher than in Wuniuzao tea garden. For annual comparison of species diversity, there was no significant difference between the same varieties (P>0.05). The community diversity of 2015 was slightly higher than that of 2016 in Baihaozao tea garden and Wuniuzao tea garden. The sequence of the close relationship between three stability values and diversity index is S_a/S_b>S_n+p/S_a+b>S_n/S_p. The difference of S_n/S_p and S_n+p/S_a+b between tea varieties in 2015 was significant (P<0.05) and no significant (P>0.05) in 2016.

ConclusionControlling the number of species and individuals in the community is an important measure to promote the stability of the community.
