Extract

An experiment to ascertain whether extermination of Glossina pallidipes could be brought about by introducing large numbers of DDT-treated oxen into its habitat was carried out in a small isolated block of bush in Tanganyika.

The oxen were sprayed with a solution of 9 per cent, w/v pure DDT and 9 per cent, w/v resin in groundnut oil. It was estimated that when sprayed once weekly about 70 per cent, of tsetse settling on them were killed, and when sprayed twice weekly, about 95 per cent. Oxen so treated were introduced in a numerical superiority of about 6 to 1 over the larger game in the bush, but were fewer than the small game.

After 3 months in which oxen sprayed once weekly were herded in tens in the bush for ten hours each day, the population of female tsetses was reduced by about 70 per cent. After a further 2 months in which oxen sprayed twice weekly were herded in fives a reduction of 80 per cent, amongst the survivors was brought about.
