摘　　要：对2年生三七进行了蓟马危害症状调查及药剂防治试验。结果显示,危害夹马石村2年生三七的蓟马主要是烟蓟马,主要危害2年生三七的叶片,导致叶片发黄、受害组织枯死或部分穿孔。对烟蓟马的田间药效试验结果表明,20%丁硫克百威、全红速效性好、持效期长。药后10 d调查,其防效分别达到99.5%和99.37%;其次是金亮瓜、40%速扑杀,防效分别达98.49%和97.59%。在三七叶片烟蓟马的化学防治中可以交替使用上述4种农药。The damage status and preventive insecticide experiment of Thrips were studied using two-year panax notoginseng at Jiamashi village, Matang town,Wenshan county. The results showed that the type of thrips was T. tabaci which infects panax notoginseng at Jiamashi village. It harms the leaves of two-year panax notoginseng. The symptoms include yellow leaves, dead tissue, and holes at leaves. The insecticide field experiment on T. tabaci showed that 20 % Carbosulfan and all red took effect faster and last longer time. The efficiencies were 99.5 % and 99.37 % respectively 10 days after the insecticides were used. Golden and 40 % Supracide also showed promising results. The efficiencies were 98.49 % and 97.59 % respectively 10 days after the insecticides were use It is suggested that four insecticides mentioned above should be alternatively applied on the insecticide prevention of T. tabaci for Panax notoginseng leaves.
