The invention relates to a beauveryia bassiana 
pesticide suspoemulsion and a preparation method thereof. The invention is characterized in that the beauveryia bassiana 
pesticide suspoemulsion includes the following materials in part by weight: 20 to 80 parts of beauveryia bassiana 
spore powder; 10 to 60 parts of emulsified dispersant; 10 to 30 parts of 
thickening agent; 10 to 30 parts of suspension stabilizer; 10 to 30 parts of spreader; 10 to 60 parts of 
sugar; and 1 to 10 parts of peptone. The activity of spores is increased, the variety of chemical aids in use is small, moreover, the suspoemulsion can be easily dissolved in water and degraded so that the environmental 
pollution can be reduced, the adhesion rate of the spores on the body surfaces of inserts is increased, the infection process of the suspoemulsion is quicker than the infection process of raw 
powder, the requirement of the formulation production process is low, the method is quite simple, and the application in fields is simple. After being diluted by water, the suspoemulsion is in the form of milky, translucent liquid, emulsification is complete, no sediments exist, the stability is high, and the suspoemulsion does not have foreign 
odor. The 
dilution factor is high, the packaging and 
transportation cost is saved, and the transportation of the 
pesticide is safe. The invention promotes the popularization and commercialization of bassiana and the development of the rural 
ecological agriculture in China.
