Abstract
A SERIES of experiments were conducted at Khartoum by a private company concerning the control of Tanytarsus lewsii, a green chironomid. During these experiments, a section of the Blue Nile was sprayed by air at Soba Village about ten miles above Khartoum, with an emulsifiable oil containing 30 per cent DDT and 0.5 per cent ‘Lissapol’. The equivalent of 440 lb. DDT was sprayed over an area in order to give a calculated DDT content of 0.09 p.p.m. It was hoped that by the time treated water reached Khartoum, the DDT concentration would have been diluted four times. The concentration of DDT at the time of arrival at Khartoum was 0.017 p.p.m. and was then maintained at a level of 0.003 p.p.m. for six hours.
