The invention discloses a method for artificially and largely raising Dioryctria pryeri indoors and application of the method. The method comprises the following steps of wrapping various coniferous tree cones with paraffin to prepare feed for the Dioryctria pryeri; collecting, culturing and raising provenances, i.e., pupae of the Dioryctria pryeri, in the field; pairing newly emerged adult females and males to mate, and isolating female moths after mating for laying eggs; collecting and culturing the eggs of the Dioryctria pryeri until larvae hatch; transferring the hatched larvae to the cones wrapped by the paraffin and raising. According to the method disclosed by the invention, the Dioryctria pryeri is raised by the natural feed which is rich in source and low in cost, cannot be influenced by seasons and does not need a complicated processing course; the method is simple and easy, and can be suitable for largely raising the Dioryctria pryeri; a large amount of stable insect sources are provided for studies on the control technique for the Dioryctria pryeri and other injurious insects similar to the Dioryctria pryeri in injurious feature and production of parasites.
