Abstract:In order to reduce spraying insecticides and protect natural enemies, an environmentally sound alternative approach using sticky colored boards for trapping important insect pests in tea plantations was being investigated. In current study, a large tea plantation in the Xihulongjing Tea original production place was chosen during the pest abundant midsummer, in which 12 colors of sticky boards including bud green and jasmine yellow were set up to trap various insects in successional 72 h in late July. Both community composition of trapped insect groups and their difference in phototaxis were analyzed. Our field trapping results are listed below. ① In total of 253870 individuals of 147 insect species, belonging to 57 families of 8 orders, were captured. Among which, Hemiptera, Hymenoptera and Diptera were the dominant groups, accounting for 98.8%, 0.6% and 0.5% of the total individuals captured, respectively. The captured insect community composition included 61 species of pests, 54 species of beneficial insects and 32 species of neutral insects. ② The citrus spiny whitefly and the tea green leafhopper were the two most dominant pest species, accounting for 94.1% and 2.0% of the total captured insect individuals, respectively. ③ On average, 10410 citrus spiny whiteflies and 86 tea green leafhoppers were caught per jasmine yellow (or bud green) board, respectively. ④ The average numbers of insect individuals caught on the dark green, peach red, sky blue, lake blue, purple, and pure white sticky boards were all less than 400, with their average numbers of insect species being less than or equal to 10, their beneficial/pest ratios (of captured individuals) being between 1/10 and 1/40, and their diversity indices H' of captured insect groups being over 1.0. The average numbers of individuals caught on bright red and apple green boards ranged from 450 to 800 with their average numbers of insect species being 9-10, their beneficial/pest ratios being 1/85 to 1/45, and H' being 0.5-0.7. On the orange, earth yellow, bud green and jasmine yellow sticky boards, the average numbers of insect individuals captured were >3700, and their average numbers of insect species captured were greater than or equal to 10, their beneficial/pest ratios were <1/100, and their diversity indices H' were <0.5. ⑤ The orange, earth yellow, jasmine yellow, and bud green sticky boards caught significantly more pest individuals than did the other eight colored boards. In the current study, a large number of insects were captured on the sticky colored boards in the Xihulongjing tea plantation during only three days in the midsummer, indicating the existence of a diverse insect community with abundant individuals that showed a significant positive phototaxis to yellow and green. The bud green and jasmine yellow sticky boards might be used to attract and kill the tea green leafhoppers and the citrus spiny whiteflies, and could partially replace insecticides with little negative impacts on natural enemies and neutral insects.
