【摘要】 在室内研究了56种植物甲醇提取物对白蚊伊蚊幼虫的生物活性。结果表明,在供试的56种植物中以莽草的生物活性最强,药后24h白蚊伊蚊死亡率达100%;其次为菖蒲,药后48h白蚊伊蚊死亡率为100%;再次为爵床和雷公藤,药后96h白蚊伊蚊死亡率均为100%;其它依次为日本冷杉、清风藤、土荆芥、常春藤、曼陀罗、鸢尾,药后96h白蚊伊蚊死亡率均在82%以上。药后96h白蚊伊蚊死亡率在50%以上的植物还有灯台莲、玉簪、交让木、万年青、金钱吊乌龟、豹皮樟等6种,对白蚊伊蚊无生物活性的植物有绣球花等26种。更多还原

【Abstract】 The insecticidal efficacy of the methanol extracts from 56 species of plants against Aedes albopictus was tested in the laboratory.The results showed that the extract from Illicium lanceolatum had the best effect on Aedes albopictus,and the mortality of the 4th larvae was 100% at the concentration of 1000 mg/kg after 24 hours of treatment.Treated with the extract from Acorus calamus at the concentration of 1 000 mg/kg for 24 hours,the mortality was 100%.Treated with the extrsct from Herba Rostellulariae and Tripterygium wilfordii for 96 hours,the mortality was 100%.Treated with the extract from Abies firma,Jabia Japonica,Chenopodium ambrosioides,Hedera helix,Datura metal and Iris chinensis for 96 hours,the mortality was above 82%.Treated with the extract from Arisaema sikokianum,Hosta plantaginea,Daphniphyllum macropodum,Rohdea japonica,Stephania cepharantha and Litsea coreana for 96 hours,the mortality was above 50%.The extracts from 26 species of plants of Viburnum macrocephalum etc had no bioactivity.更多还原
