Method for safely controlling parasitic mites on osmia excavata alfken

The invention belongs to the technical field of pesticide preparations, and in particular relates to a mite killing method for safely controlling parasitic mites on osmia excavata alfken. The method for safely controlling the parasitic mites on the osmia excavata alfken comprises the step of exposing osmia pupaes and/or bee tubes containing the parasitic mites to a mite-killing preparation of effective dosage, wherein the effective components of the mite-killing preparation comprise dicofol, pyridaben and propargite. The mite killing method is developed specially for safely controlling the parasitic mites on the osmia excavata alfken, and although the effective components of the preparation adopted by the method are all common acaricides in the prior art, a great reduction of a toxicity effect of the preparation on the osmia and the osmia pupaes is surprisingly discovered on the basis of further improving the specificity for the parasitic mites on the osmia excavata alfken after the preparation is subjected to matching and mutual influence, so the method is more suitable for safely controlling the parasitic mites on the osmia excavata alfken, and an unexpected technical effect is achieved.
