The invention belongs to the technical field of environmental ecology, and relates to a method for controlling alternanthera philoxeroides by using omnivorous insects and/or monophagous insects. The method comprises the following specific steps: firstly, a field invaded or easily invaded by alternanthera philoxeroides is selected; then omnivorous insects and monophagous insects are captured under the field natural condition and placed in an insect culture device to expand the population scale; in order to guarantee insect populations, the number and male-female proportion of each kind of insects put into the insect culture device during primary culture are limited; in addition, in order to prevent population degeneration, field insect sources need to be supplemented into the culture device at set intervals; the cultured omnivorous insects and/or monophagous insects are put into a field invaded by alternanthera philoxeroides; the result shows that the biomass of the overground part and the underground part of alternanthera philoxeroides is obviously reduced, and the reduction amplitude of the biomass of the overground part and the relative growth potential reaches 50%, so that the growth of alternanthera philoxeroides can be obviously inhibited after the insects are put, and the effect is obvious.
