Breeding method and breeding and propagation device for drosophila parasitoid wasps

The invention provides a fruit fly parasitic wasp breeding method and a breeding propagation device, and belongs to the technical field of agricultural pest biological control. The breeding method comprises the following steps: (1) enabling adult fruit flies to lay eggs on a fruit fly culture medium, collecting the eggs, and culturing until larvae pupate; (2) when the drosophila pupae in the step (1) grow to 2-day-old pupae, inoculating for 24 hours, then taking out parasitic wasps, and removing the drosophila culture medium; (3) collecting drosophila pupae parasitized by the parasitic wasps, and continuously culturing the drosophila pupae; (4) removing fruit fly adults which are not parasitized; (5) collecting parasitized drosophila pupae before eclosion of the parasitic wasps; and (6) after eclosion of the parasitic wasps, performing low-temperature treatment, quickly collecting adult wasps, and storing bee species. The breeding method is simple and easy to implement, small in breeding space, low in cost an
