Abstract:

To effectively control pests using the natural enemy spider in tea plantation, field investigations were conducted to know the dynamic change of the spider community and leafhopper population in the forest ecological model tea plantation and conventional tea plantation. The results showed that the number of spider population in the forest ecological model tea plantation was significantly higher than that in the conventional tea plantation, while the number of leafhopper population was significantly lower compared with that in the conventional tea plantation. As to spider communities, the species and the number of spiders that remained in their webs and were observed moving were similar in forest ecological model tea plantation, but spiders were mainly observed moving in conventional tea plantation. The spider species diversity index, evenness index, richness index and dominance index were higher in the forest ecological model tea plantation. The spider population had obvious phenomenon of following the leafhopper and significant control effect on leafhoppers in the forest ecological model tea plantation; while the spider populations were less than leafhopper populations in the conventional tea plantation, and the control effect in the peak of leafhopper was not obvious.

Key words: tea plantation, forest ecological model, spiders, leafhopper, temporal dynamics, diversity
