滇南茶小绿叶蝉综合防治技术与应用

作者根据1988～1993年对云南省南部西双版纳和思茅地区茶园中的茶小绿叶蝉的生物生态学特性研究结果,遵照IPM的要求设计了:①以采代治,②试用新防治历,③按防治指标防治,④生物防治,4个分项防治措施,并进行了分项小区试验和综合利用这些防治措施的综合防治试验。试验结果表明:设计的4项单一防治措施和综合防治措施,在对茶叶产量和质量无影响,而又能控制茶园小绿叶蝉为害的情况下,经济和人力投入都比传统的化学防治方法少,而且降低了茶叶中农药残留量。

STUDIES ON THE INTEGRATED MANAGEMENT TECHNIQUES OF SMALLER GREEN LEAFHOPPER IN TEA PLANTATION OF SOUTH YUNNAN

Based on the bionomics studies carried out in 1988-1993 on smaller green leafhopper Empoasca flavescens (F. ) in tea plantations in Xishuangbanna and Simao Areas, Yunnan Province,four integrated management practices of this insect pest,namely: (1)to pick tea instead of chemical control; (2)to try out new control calender; (3)to practice action threshold;and (4) to use biological control,were proposed and tested separately and synthetically in field plots. It was confirmed that as the population of smaller green leafhopper was kept under control by applying these new practices, there was no harmful effect of them separately and synthetically on tea production and quality, the cost of control was lower than that of the traditional chemical control,the insecticide residue in tea production was effectively reduced.
