摘要: 采用虫体浸渍法和叶碟浸渍法测定了甘肃天然草地30种有毒植物提取物对菜粉蝶4龄幼虫的拒食和触杀作用。结果表明,铁棒锤、贝加尔唐松草、灰绿黄堇、黄帚橐吾、冷蒿(小白蒿)、骆驼蓬和狼毒甲醇提取物对菜粉蝶4龄幼虫具有很强的拒食和触杀作用,48 h的拒食率为82.23%~100.00%,触杀死亡率为80.00%~94.12%;露蕊乌头、青藏大戟、狼毒大戟和泽漆甲醇提取物具有很强的拒食作用,48 h的拒食率为95.14%~97.62%。综合分析,铁棒锤、贝加尔唐松草、灰绿黄堇、黄帚橐吾、冷蒿(小白蒿)、骆驼蓬、狼毒、露蕊乌头、青藏大戟、狼毒大戟和泽漆11种有毒植物具有研究和开发利用价值。

Abstract: Anti-feeding and contact effects of extracts from 30 kinds of poisonous plants from natural grasslands of Gansu province against fourth instar larvae of Pieris rapae were assessed by immersion methods. Methanol extracts from Aconitum pendulum, Thalictrum baicalense, Corydalis adunca, Ligularia virgaurea, Artemisia frigida, Peganum harmala, and Stellera chamaejasme had very strong anti-feeding and contact effects against the larvae of P. rapae, with anti-feeding rates between 82.23%-100.00% and contact mortalities between 80.00%-94.12% after 48 hours. Methanol extracts from A. gymnandrum, Euphorbia tibetica, E. fischeriana and E. helioscopia had very strong anti-feeding effects, of 95.14%-97.62% after 48 hours. The eleven kinds of poisonous plants were A. pendulum, T. baicalense, C. adunca, L. virgaurea, A. frigida, P. harmala, S. chamaejasme, A. gymnandrum, E. tibetica, E. fischeriana and E. helioscopia. They are worth further research and development.
