You missed how the story continued: "With widespread resistance of A. culicifacies to DDT, malathion spraying was introduced in 1975 in areas of P.falciparum transmission affording protection to nearly one million people. Towards the end of 1976 DDT spraying was completely discontinued and during 1977 exclusively malathion was used as an adulticide."
