Study on the anti-cowpea aphid action of a lectin from Alocasia odora

摘要: 从海芋Alocasia odora(Roxb)C．Koch不同部位提取出海芋凝集素粗品，并将其分离纯化得到层析纯样品，研究表明，海芋凝集素对豆蚜有较强的抗生作用，其中以胃毒作用为主，有一定的生殖抑制作用，对豆蚜的蜜露分泌有一定影响。

Abstract: Plant lectin is a sort of plant protein, which can be used to control pests. It is very safe to animal, environment, and very stable in many facets. In this paper, crude lectins of Alocasia odora lectin (AOL) were obtained from Alocasia odora (Roxb) C. Koch. Then obtained chromatographic purified AOL by fraction. It was identified that AOL had strong anti-aphid action, including most stomach toxic, quite reproductive inhibition and honeydew secretion inhibition.
