【摘要】 从功能反应的角度提出了天敌作用定量评价的功能反应—血清法,并给出了其改进、推广形式及应用实例.该方法可推出从血清学角度不能得到的结论.它通过定量计算害虫的被捕食(寄生)数量来评价天敌的作用,具有适用性广、能随时进行定量评价、易于在逐日种群动态模型中表示天敌作用引起的存活率等特点,而且较好地解决了室内研究和田间调查资料不能充分利用的问题.该方法为评价自然天敌对害虫的控制作用有一定的参考价值.更多还原

【Abstract】 A method,named functional response serological method was developed to quantitatively evaluate the role of natural enemies form the view of functional response.The improved and extended form as well as application examples was given.It could get some results that were not given from serological views.It evaluated the role of natural enemies based on the number of pests fed,had good adaptation,and some characteristics that the quantitative evaluation could do at any time.The expression of the survival rates which were set off by natural enemies was easy in daily insect pest population models.It is valuable for improving the evaluation of natural enemies.更多还原
