Abstract

The invention relates to a breeding method of pyemotes tritici, which comprises the following steps of: placing original hosts parasitized by the pyemotes tritici into a dactylethrae, and placing alternative hosts into a culture dish, placing the dactylethrae into the culture dish, inoculating for 24-48h and then transferring the parasitized alternative hosts into the dactylethrae to culture to serve as protospecies of the pyemotes tritici; placing the protospecies of the pyemotes tritici and the alternative hosts into the culture dish according to the method, inoculating for 48-72h and then transferring the parasitized alternative hosts into the dactylethrae to culture to breed the pyemotes tritici. The method provided by the invention is concise in operation, a used device is simple and available, and the inoculation method combining the dactylethrae with the culture dish greatly reduces the damage on the physogastry body of the pyemotes tritici caused by the activity of the alternative hosts and increases the parasitism rate of the pyemotes tritici.
