摘要
In order to improve the development step of tea industry,the pest investigation was carried out in main Xinyang tea producing area from the year of 2005 to 2008,and 1 600 specimens were collected. The results showed that there were 70 species pests,containing 8 orders and 35 families. Among the pests,there were 11 species such as Boarmia obliqua Wehrli,Euproctis pseudoconspersa Strand,Dasychira barbarana Matsumura,Iragoides fasciata Morre,Clania minuscula Butler,Adoxophyes orana Fisher von Roslerstam,Hypomeces squamosus Fabricius,Sympiezomia citre Chao,Empoasca flavescens Fabricius,Toxoptera aurantii Boyer and Aleurocanthus spiniferus Quaintance,which were significantly harmful to the tea plant. Pest non-pollution control techniques were developed.
