The invention discloses an insecticidal composition containing
beauveria bassiana and spinetoram. The insecticidal composition is characterized by being prepared from an effective component A, i.e., the
beauveria bassiana, and an effective component B, i.e., the spinetoram, wherein the quantity of the effective component A, i.e., the
beauveria bassiana, is 5 to 40 billion spores per
gram; the content of the effective component B, i.e., the spinetoram, is 5 percent to 50 percent; the preferable quantity of the effective component A, i.e., the
beauveria bassiana, is 20 to 40 billion spores per
gram; the preferable content of the effective component B, i.e., the spinetoram, is 10 percent to 30 percent. The insecticidal composition disclosed by the invention has a remarkable synergetic effect;the dosage of
pesticide can be reduced, the residual amount of the
pesticide on crops is reduced and the environment
pollution is alleviated; the insecticidal composition is safe to human and
livestock and has good environmental compatibility, and
insect pests do not easily have
drug resistance. The insecticidal composition has a function of preventing and controlling lepidoptera pests and especially has a remarkable prevention and
control effect on cabbage /
plutella xylostella, corn /
ostrinia nubilalis and paddy rice /
cnaphalocrocis medinalis.
