A method of determining the larvicidal activity of stomach-poison insecticides on house-flies


, : A method of determining the larvicidal activity of stomach-poison insecticides on house-flies. Trudy Vsesoyuznyi Nauchno issledovatel' skii Institut Veterinarnoi Sanitariirecd 1981; 63: 9-13

To determine the toxicity of the thermostable beta -exotoxin of Bacillus thuringiensis (as Thuringin) for Musca domestica L., third-instar larvae were reared on a nutrient medium containing wheat-bran, milk and water in the ratio 3:1:6. The amounts of a solution of the test preparation that were added to the medium were in geometrical progression and there were 4 replicates of each.
