利用15种中草药水溶性提取液对怀牛膝根结线虫二龄幼虫及卵进行室内离体活性测定.结果表明,供试的15种中草药提取液对怀牛膝根结线虫幼虫和卵的毒杀活性差异显著,其中,用徐长卿、黄姜、喜树、藜芦提取液处理后,二龄幼虫72 h的校正死亡率分别为95.46％、95.00％、91.79％、90.47％,杀线虫活性强度均达到“++++”,1～30 d卵的孵化抑制率分别为94.30％、94.13％、90.89％、91.13％,卵的校正死亡率分别为80.40％、82.23％、75.54％、78.87％.徐长卿、黄姜、喜树、藜芦提取液对怀牛膝根结线虫的杀虫、杀卵效果较好.
Nematicidal Activities of 15 Kinds of Chinese Herb Extracts against Root-knot Nematode of Achyranthes bidentata
The nematicidal activities of the water-soluble extracts from 15 kinds of Chinese herbs against root-knot nematode of Achyranthes bidentata Bl. Were investigated. The results showed that the activities of extracts from 15 plant species belonging to 13 families against the 2nd instar larvae and eggs of root-knot nematode were significant. Cynanchum paniculatum (Bunge) Kitaga-wa, Dioscorea zingiberensis C. H. Wright, Camptotheca acuminate Decne. And Veratrum nigrum L. Caused the corrected mortalities of 2nd instar larvae within 72 h of 95. 46%,95. 00%,91. 79% and 90. 47% , respectively. The hatching inhibition rates of eggs were 94. 30 % ,94. 13% ,90. 89 % and 91. 13% within 30 days and the corrected mortalities of eggs were 80. 40%, 82. 23%, 75. 54% ,and 78. 87% ,respectively. The nematicidal activities of the extracts from C. Paniculatum (Bunge)Kitagawa,D. Zingiberensis C. H. Wright,C. Acuminate Decne. And V. Nigrum L. Were bet-ter than those of others.
