Product Description
For evaluating fly sprays based on the technique described in Soap and Sanitary Chemicals (Feb 1943) Vol. 19 p 101-104, 128 with certain modifications.
The dosage for mortality tests is 0.2 ml per sprayer (total 0.4 ml). The percentage mortality obtained with the official test insecticide at a dosage of 0.4 ml should be between 30 per cent and 55 per cent. Under different conditions of fly breeding and testing it might be necessary to vary the dosage in order to obtain kills within this range.
