摘　　要：对应用于昆虫生态学研究的现代生物学方法(同工酶电泳技术、RAPD、RELP、DNAfp、SSCP、DSCP)及其在昆虫种群遗传结构、生物型鉴别、天敌识别及利用、鉴定害虫抗药性、滞育机制、亲系识别以及昆虫与植物之间关系等研究方面的应用进行了论述。The theory and application of modern biotechnique improve greatly the development of insect ecology, especially at the level of protein and DNA uncovering life phenomena which can not be resolved by traditional ecological methods. In this paper, the author reviewed many modern biological techniques (allozyme electrophoresis, RAPD, RELP, DNAfp, SSCP, DSCP) applied in insect ecology and their applications in insect population genetic structure, biotype distinguishment, certainty of natural enemies, diapause mechanism, relationships between insects and plants, and kin recognition etc.
