两品种茶园茶蚜和假眼小绿叶蝉天敌优势种的比较
The dominant species of natural enemies of Toxoptera aurantii and Empoasca vitis in two tea gardens with different varieties
摘要
Abstract
In order to conserve and utilize natural enemies for a comprehensive control of insect pests in tea plantation,the dominant natural enemies of Toxoptera aurantii and Empoasca vitis were evaluated in both Wuniuzao tea garden and Baihaozao tea garden.The number of pests and their main natural enemies in the two tea gardens were compared using T-test.The results showed that the differences in 2 pests and 8 enemies between two tea gardens were not significant in spring-summer seasons.The differences of Oxyopes sertatus (3.7160) and Neoscona theisi (4.3144) in autumn-winter seasons were highly significant.In the Wuniuzao tea garden,the differences of Theridion octomaculatum (2.6298) between the spring-summer season and the autumn-winter season were significant and in the Baihaozao tea garden,the difference ofNeoscona theisi (4.0056) was highly significant.The numbers of Erigonidium graminicolum (2.8160) and Oxyopes sertatus (2.1408) were significantly different and the others were not significantly different.Grey correlation degree method and niche analysis method were applied to analyze the quantity and temporal and spatial relationships between two insect pests and their main natural enemies.The top three dominant natural enemies of Toxoptera aurantii were Tetragnatha maxillosa,Misumenops tricuspidatus and Oxyopes sertatus,but they had different orders;for Empoasca vitis,the first and second dominant natural enemies were Oxyopes sertatus and Tetragnatha maxillosa and the third natural enemy was different.In autumn-winter seasons,the top three dominant natural enemies of Toxoptera aurantii in the two tea gardens were Tetragnatha squamata and Theridion octomaculatum,and the top three dominant natural enemies of Empoasca vitis were Erigonidium graminicolum and Oxyopes sertatus.Compared to the Baihaozao tea garden between spring-summer seasons and autumn-winter seasons,the same natural enemy of Toxoptera aurantii among three dominant species in the WuNiuZao tea garden was Misumenops tricuspidatus,and in the Baihaozao tea garden the same natural enemy of Toxoptera aurantii was Tetragnatha maxillosa.As for Empoasca vitis,the same natural enemy in the Wuniuzao tea garden was Oxyopes sertatus,and the same natural enemies in the Baihaozao tea garden were Tetragnatha maxillosa and Oxyopes sertatus.The tea variety had a major impact on the dominant species of natural enemies of Toxoptera aurantii in spring-summer seasons.The biophysical and biochemical conditions were not exactly the same in two different tea gardens,indicating the different effects on the population dynamics of the pests and their natural enemies in tea gardens.关键词
