为筛选出一种对陕西茶区小贯小绿叶蝉（Empoasca onukii Matsuda）有良好防效且对天敌蜘蛛影响小的植物源农药，并明确其经济有效的使用剂量，选用3种高效、低毒、低残留的植物源农药对小贯小绿叶蝉进行田间药效试验。结果表明：0．6％苦参碱水剂6．3 g·hm-2对小贯小绿叶蝉的速效性及持效性均优于7．5％鱼藤酮乳油67．5 g·hm-2和1．5％除虫菊素水乳剂27 g·hm-2；进一步研究表明，0．6％苦参碱水剂在浓度为13．5和6．75 g·hm-2时，对小贯小绿叶蝉的防效与2．5％联苯菊酯微乳剂18．75 g·hm-2的防效相当。因此，在田间使用0．6％苦参碱水剂的推荐剂量为6．75～13．5 g·hm-2。

In order to screen out a botenical pesticide with explicit dosages to control Empoasca onukii Matsuda effectively which has little effect on natural enemy spiders in Shaanxi tea region field efficacy on Empoasca onukii Matsuda were tested by 3 kinds of botanical pesticide which was efficient ,low toxicity and low residual . The field trial results showed that the control effect of 0 .6% matrine AS at the dosage of 6 .3 g·hm-2 was more sustainable and effective to against Empoasca onukii Matsuda compared with the use of 7 .5% rotenone EC at the dosage of 67 .5 g·hm-2 and 1 .5% pyrethrins WE at the dosage of 27 g·hm-2 .Further research found that the use of 0 .6% matrine AS at the dosage of 13 .5 g·hm-2 ,6 .75 g·hm-2 had almost the same control effects with the use of 2 .5% bifenthrin SC at the dosage of 18 .75 g·hm-2 against Empoasca onukii Matsuda .The rec-ommended usage in fields of 0 .6% matrine AS was 6 .75~13 .5 g·hm-2 .
