The invention belongs to the technical field of agriculture and forestry injurious insect biological control, and discloses an encarsia formosa breeding method. The method comprise the following steps of 1 host aleyrodid production, wherein aleyrodid species are released into a breeding chamber, taro seedlings are adopted as hot plants, and aleyrodid breeding is performed; 2 encarsia formosa production, wherein encarsia formosa species are released into the breeding chamber in the step 1, and encarsia formosa breeding is performed; 3 honey bee pupae collection performed when 60-70% of aleyrodid nymphs on the taro seedlings become black honey bee pupae. According to the technical scheme, the problem that after encarsia formosa breeding is performed, the host plants cannot generate economic benefits is solved, economic benefits are improved, meanwhile, the encarsia formosa breeding efficiency is improved, man hours are shortened, and breeding management is more convenient.
