The invention discloses detection test paper for pyrethroid pesticide residues in foods. The detection test paper is prepared by immersing filter paper in a mixed solution and drying, wherein the mixed solution is prepared from the following components: 3g/L to 70g/L of phosphate buffering solution, 10g/L to 100g/L of chloramine T solution, 6g/L to 120g/L of isonicotinic acid-barbituric acid color developing agent and 5mL to 60mL of dichloromethane-methanol mixed solution, and a solvent which is de-ionized water. The volume ratio of dichloromethane to methanol in the dichloromethane-methanol mixed solution is (80 to 110) to 1. The phosphate buffering solution is obtained by mixing citric acid and phosphate. The mass ratio of isonicotinic acid to barbituric acid in the isonicotinic acid-barbituric acid color developing agent is (1 to 5) to 1. Before the detection test paper is used, the foods are crushed and sieved; then ethyl acetate is added for extracting; centrifuging is carried out and then a proper amount of supernatant is taken; the supernatant is volatilized to be nearly dry and then is dissolved with ethanol to obtain a sample to be detected. The detection test paper provided by the invention is used for detecting the pyrethroid pesticide residues in the foods and operation is simple and rapid; rapid detection on the pyrethroid pesticide residues in agricultural and sideline products is realized, and the detection test paper is suitable for rapid detection on site and in primary laboratories.
