Abstract: Objective:To observe the larvicidal activity of the dried genetically engineered Cyanobacteria against the larvae of Culex pipiens pallens.Methods:Desiccation,storage and detection of larvicidal activity.Results:The dried genetically engineered Cyanobacteria still kept high toxicity.And the longer the dried ones were stored,the lower toxicity they had.But there were no significant differences within the three dried genetically engineered Cyanobacteria.Conclusion:The shuttle plasmid in Cyanobacteria kept stable and high expressing and the dried genetically engineered Cyanobacteria might be a prospective insecticide for field control.
