一、研究概况昆虫利它素(Kairomone)是一种广泛存在于动植物体中的“他感作用化学物质”(Atleochemics),在种间的化学通讯中起着媒介作用。Brown(1970)根据利它素的生物效应,最先予以定名,并作了如下定义:一种对接受者的(?)处大于释放者的种间化学信息物质。他的工作得到广大生物学家的承认。自此,利它素这一名词开始被广泛采用。利它素具有修饰昆虫行为的作用,它引诱植物昆虫趋向寄主植物,天敌昆虫趋向寄主或 First, the research overview Insect kairomone (Kairomone) is a widespread existence in animals and plants in the “sense of the role of chemical substances” (Atleochemics), chemical communication between species play a mediocre role. Based on the biological effects of altax, Brown (1970) first naming it and defining it as follows: An interspecies chemical informative substance that has a greater (?) To the recipient than the deliverer. His work has been recognized by a large number of biologists. Since then, the term ritalin has been widely adopted. Ritalin has the effect of modifying insect behavior by inducing plant insects to tend to host plants, and natural enemy insects tend to host or
