摘　　要：为了对茶园碧蛾蜡蝉的防治提供参考,对贵阳羊艾茶园碧蛾蜡蝉的发生规律进行了调查,并开展了药剂防治试验。结果表明:碧蛾蜡蝉在贵阳1年发生1代,以卵越冬,若虫发生期在4月中旬至8月上旬,盛发期为6月上中旬;成虫发生期在7月上旬至10月下旬,盛发期为8月中下旬;虫口发生量与气候环境关系密切。成虫期施药防治效果明显高于若虫期施药,25%吡蚜酮粉剂、5%阿维菌素乳油及5%吡虫啉乳油对成虫的防治效果较好,药后14d,防效在80%以上。The occurrence regularity and control effect of G. distinctissima in tea plantation of Yang＇ai tea garden of Guiyang were studied to provide the basis for controlling G. distinctissima in tea plantation. The results showed that G. distinctissima had one generation per year and overwintered by eggs. The nymph began at the middle ten days of April, and over at the beginning of August. The high time for nymph hatch was in the beginning and middle of June. Adults from July to October. The high time for adult eclosion was in the middle of August. Occurrence period and occurrence amount were closely related to the environmental conditions. The effect showed that the controlling effect to adults was better than to nymphs. The control effect of 25% pymetrozine WP, 5% avermectin EC and 5% imidacloprid EC were more than 80% 14 days later.
