摘要/Abstract

摘要： 目的：观察3种基因工程杀蚊幼蓝藻对不同龄期淡色库蚊幼虫的杀灭效果。方法：利用不同浓度基因工程藻，分别作用于不同龄期淡色库蚊幼虫，计算死亡率。结果：3种基因工程藻对不同龄期淡色库蚊幼虫杀灭作用相似；在藻细胞浓度低于10⁴cels／ml时，杀灭作用由强到弱依次为Ⅰ龄、Ⅱ龄、Ⅲ龄末Ⅳ龄初幼虫；而当藻细胞浓度高于10⁵cels／ml时，对该蚊不同龄期幼虫的杀灭作用均高效。结论：应用基因工程藻现场控制蚊幼虫宜尽早喷施，可提高杀灭效果。

Abstract: Objective:To observe the effect of three kinds of genetically engineered cyanobacteria against different stage larvae of Culex pipiens pallens.Methods:The recombinant cyanobacteria of different concentration respectively acted on different stage larvae of Culex pipiens pallens and calculate the mortality of larvae.Results:The smaller stage of larvae of Culex pipiens pallens, the more high toxicity against its larvae the recombinant cyanobacteria have.Discussion:When the larvae of Culex pipiens pallens are Ⅰ or Ⅱ stage larvae in field,the recombinant cyanobacteria should be used.
