Abstract:
Bacillus thurinensis and Bradysia ordoriphaga were used as experimental materials.With the method of soaking chives stem sections，five soaking time of chives stem sections,five diluted concentration of B.thuringiensis and four observation time after treatment were designed in the experiment.The experiment purpose was to give the best soaking time,diluted concentration and observation time when indoor toxicity of B.thurinensis to B.ordoriphaga larva was tested.The results showed by difference significance analysis，that the optimal test factors soaking time of leek stem sections was 60 seconds，diluted concentration of B.thuringiensis was 500 mg?L-1，observation time after treatment was 24 hours.Under the above experimental conditions，the average mortality of B.thuringiensis larva was 90%.Toxicity equations of diluted concentration of B.thuringiensis were simulated at different observation time after treatment.When the observation time after treatment was 12 hours，semi-lethal concentration LC50 was 49.40 mg?L-1.
