The following is substantially the author's summary of this account of experiments on the effect of DDT and parathion on house-flies (Musca domestica vicina Macq.) of a laboratory colony originating from a strain collected in Cairo. The LD50 of DDT applied topically was 1.4 and the LD95 3.6 mu g per female fly, based on the mortality 24 hr. after exposure. The highest dose tested that caused no signs of poisoning after 24 hr. was 0.015 mu g per fly.
