Abstract

Abstract: The purpose of this study was to comprehensively evaluate the dominant natural enemies of Breuipalpus oboyats in autumn and winter tea gardens. The relationship between natural enemies and B.oboyats in time and space was studied by niche analysis and geostatistics combined with angular cosine coefficient method. According to the comparison of the sum of closeness index, it is found that the top three natural enemies (from large to small) that are most closely related to B.oboyats in the "Nongkangzao" tea garden are Plexippus paykulli, Clubiona japonicola, and Xysticus ephippiafus ; "Pingyangtezao" tea garden are X.ephippiafus, Plexippus setipet, and Oxyopes sertatus . In front of the two tea gardens, one of the three natural enemies is the same. The evaluation of the comprehensive closeness index of the two tea gardens shows that the top three natural enemies most closely related to B.oboyats are X.ephippiafus, P.paykulli, and O.sertatus. X.ephippiafus is the most important natural enemy of B.oboyats in tea gardens in autumn and winter; the dominant natural enemies of the same pests in different varieties of tea gardens in the same area are often different.
