Abstract: Objective:To pioneer out both efficacy's assessment indices and optimum formula of fuse-induced smoke insecticide of B.germanica.Methods:Assessment indices based on technological quality must be economic and convenient to use and its optimum formula is weeded out by means of orthogonal layout statistics.Result:Such indices of different weight as fuse-induced difficulty,combustion,jet,smoking time,quantity of aerosol,et al,are then conformed to principles of orthogonal layout for deducing the optimum formula.Under the formula,the smoke insecticide compounded with pesticides like permethrin,d-cyphenothrin,cypermethrin,S₂,et al,and materials,for example,potassium,carbon power,ammonium chlorate,talcum power,et al,is easily fuse-induced at the appropriate speed of 30-50s/10g,and of no combustion,no sparks in the residual dregs,although good smoke-carrying distribution of aerosols with their diameters varying from≤15μm(50.8%),≤30μm(26.4 %),to>30μm(22.8%) in the samples and less expensive cost.Conclusions:With these indices objective,accurate,sensitive,economic and convenient to use,the smoke insecticide compounded is so good that it is worth expanding in the real life.
