| Abstract: | Objective To observe the efficacy of double microorganism against mosquito larvae,explore the suitable insecticides and application cycle for killing mosquito larvae.Methods Selecting a randomized experimental area sewage pit and controlling area sewage pit by 5ml/m2 of the liquid,diluted 10 times,even with an electric sprayers to spray on the surface of the water and observe the mosquito density.Results After spraying for 1-20 days,the effect of killing mosquito larvae was up to 100%.The killing rate was 72.41% after 30 days.By data analysis,it is suitable to spray insecticides with an interval of 20 days.Conclusion Double microorganism for killing mosquito larvae has instantaneous and lasting effect.It is an ideal insecticides for killing mosquito larvae. |
