Applied Technology of Botanical Pesticides against Empoasca pirisuga Matumura

[Objectives] The paper was to explore the control effects of different botanical pesticides against Empoasca pirisuga Matumura. [Methods] 5% Eucalyptol SL, 0.5% matrine SL and 50% thiacloprid WDG were used to control E. pirisuga , and the decline rate of insect population was investigated. [Results] Eucalyptol had good control effect on E. pirisuga , with slow effect but long duration. It was harmless to natural enemies in tea gardens, with high safety and no chemical injury. [Conclusions] The study provides a theoretical basis for the application of botanical pesticides in tea production.

防治茶小绿叶蝉的药剂筛选初探

采用5种杀虫剂氟氯氰菊酯、联苯菊酯、硫丹、啶虫脒、烟碱防治茶小绿叶蝉的田间药剂筛选试验,结果表明:氟氯氰菊酯、联苯菊酯、硫丹、啶虫脒对茶小绿叶蝉的防治效果较好,处理防效均在97%以上;而烟碱对茶小绿叶蝉的防治效果相对较差,处理防效为87.10%。综合各药剂的持效性、毒性和防治效果的特点,防治茶小绿叶蝉较理想的药剂为联苯菊酯、烟碱或啶虫咪。
