研究了7种植物甲醇提取物对蓖麻虫的生物杀虫效果。赤马尾草、马蹄草、牛膝草、马兜铃草、鹰嘴蕨和Raphanus raphanistrum提取物对幼虫生长有抑制作用。治疗10 d后，赤弧菌毒性最大，死亡率为63%，其次是哈玛拉弧菌，死亡率为58%。赤藓和水杨分别使羽化率降低66%和19%。与对照相比，木桐、金针叶和金针叶提取物可缩短幼虫期，而木桐和金针叶提取物可延长幼虫期。赤藓、哈玛草、伊娃草和白藓提取物对F1后代的产生有抑制作用。通过SDS-PAGE测定，幼虫具有三种α -淀粉酶同工型。饲喂处理过的仔鱼α -淀粉酶活性低于饲喂未处理过的仔鱼。赤藓和苦参是最有效的提取物。这些植物提取物可能有助于减少该害虫对种子的损害。(c) 2007 Elsevier Ltd.版权所有。
Bioinsecticidal effects of methanol extracts from seven plant species on Tribolium castaneum were investigated. Centaurium erythraea, Peganum harmala, Ajuga iva, Aristolochia baetica, Pteridium aquilinum and Raphanus raphanistrum extracts inhibit growth of larvae. C erythraea was the most toxic with 63% mortality 10 days after treatment, followed by P. harmala with 58%. C erythraea and P. aquilinum reduce the emergence rate respectively of 66% and 19%. The duration of larval period was shortened by Launaea arborescens, P. aquilinum and A. iva extracts, whereas R. raphanistrum and P. harmala extracts extend the larval period when compared to the control. Extracts of C erythraea, P. harmala, A. iva and A. baetica inhibited F1 progeny production. Larvae possess three alpha-amylase isoforms as determined by SDS-PAGE. Larvae fed on treated diet had lower alpha-amylase activity than larvae feed on untreated diet. C erythraea and P. harmala are the most potent extracts. These plant extracts could be useful to reduce seed damage caused by this pest species. (c) 2007 Elsevier Ltd. All rights reserved.
