Abstract: In order to evaluate the entrapping effect of the bud green, the olive yellow-green, the jasmine yellow and the snow white sticky plates on various insects in tea gardens and to discuss the possibility for them to be applied in controlling the important pests, the luving tests, were conducted. In July when the various species of insects occurred in tea gardens, the plates were set in 0.5βhm2 tea gardens to trap the insects for 48βh, in the tea gardens of Chongqing Suburbs, in Songyang County of Zhejiang Province and in Magushan Tea Farm of Anhui Province, respectively. The results showed that the most of trapped insects belonged to Homoptera, in which the attracted amounts of harmful insects was abundant whilst the those of beneficial insects was much small, and the difference in both amounts reached the level of P<0.01. Bud green, olive yellow-green, jasmine yellow and snow white sticky plates showed much stronger trapping effect on nymphs and adults of tea green leafhoppers and adults of citrus spiny whiteflies than snow-white stiky plates. From bud green, olive yellow-green to jasmine yellow, green ingredient decreased whilst yellow ingredient increased, accordingly, the number of trapped leafhoppers decreased whilst the number of trapped whiteflies increased. It is proposed that bud green and jasmine yellow sticky plates could be used to trap the leafhoppers and the whiteflies, respectively.

Key words: coloured sticky plates, trapping, tea green leafhoppers, citrus spiny whiteflies, various insects in tea gardens
