摘要
采用乙醚、丙酮、乙醇、石油醚４种有机溶剂浸提和热提苦瓜叶片，以提取液涂抹桑叶和甘蓝叶后分别饲喂家蚕（ＢｏｍｂｙｘｍｏｒｉＬｉｎｎｅ）和菜青虫Ａｒｔｏｇｅｌａ（ｐｉｅｒｉｓ）ｒａｐａｅＬｉｎｎａｅｕｓ。试验结果表明，４种有机溶剂提取液处理试虫，其取食量降低，生长速率缓慢，存活率下降，其中以乙醚提取液的作用最强。
The balsam pear leaves were macerated and hot-extracted with four organic flux including, ether, acetone, ethanol and petroleum ether respectively. The larvae of Bombax mori and pieris rapae were raised by the leaves of mulberry and wild cabbage which were smeared by the extracts liquids separately. The experimental results showed that the consumption of leaves decreased, the growth and survival rate also decreased. Among the four extract liquids, the effect of ether extract liquid was the most strong
