Abstract

The tea productions, main predators and insects pests of five mixed planting tea plantations were analyzed in Puer city. The effects of mixed planting on productions of fresh tea leaves, predators and insect pests in tea plantation were investigated. The results showed that predatory spiders and Empoasca vitis were most important predator and pest respectively in five tea plantations. Numbers of Empoasca vitis in mono-tea plantation were significantly higher than mixed planting plantation. The orders of spider individual numbers in five tea plantations were as follows: mixed planting of Dimocarpus longan and tea>mixed planting of Castanea mollissina and tea>mixed planting of Alstonia scholaris and tea> mixed planting of Cunninghamia lanceolata and tea> mono-tea plantation. The pests in mixed planting of Dimocarpus longan and tea plantation were significantly less than those in other tea plantations. There were no significant differences among mono-tea plantation, mixed planting of Castanea mollissina and tea plantation, mixed planting of Alstonia scholaris and tea plantation, and mixed planting of Cunninghamia lanceolata and tea plantation, mixed planting of Dimocarpus longan and tea plantation were the best mixed types because of moderate light, highest production, most predators and less pests. There were significant negative correlations between amounts of predatory spider and Empoasca vitis as well as other insect pests in different season which can produce a good representation by used of Logarithm equation.
