Just read the WHO reports. Here's what they said about DDT use in Ceylon. "The situation in Ceylon is a prime example of how rapidly and extensively malaria can return to an area if the protection of an active malaria program is not continued until complete eradication. Following a countrywide malaria eradication campaign in the 1950's and early 1960's, the number of confirmed malaria cases reached lows of 31 in 1962 and 17 in 1963, when full scale house spraying was partially withdrawn, and subsequently terminated in 1964."
The result was predictable. More than a million cases of malaria occurred throughout the country by 1968. Doesn't much look like DDT was ineffective does it? If, and when, its effectiveness begins to diminish, I would hope that a similar substitute would be discovered by scientists. Unfortunately, because of the superstitious and self-serving antagonists to its use, it is likely that there will be no work on a replacement for this cheap, effective, and remarkably safe pesticide.

DDT becomes ineffective so quickly now because DDT-resistant mosquitoes exist at low frequency in the global mosquito population and, when a local population is sprayed, a strong force of selection in favor of the resistant mosquitoes is immediately created. It is only a matter of time before the resistant mosquitoes take over. Figure: increase in frequency of pesticide resistance in mosquitos after spraying with DDT. A sample of mosquitos was captured at each time indicated and the number that were killed by a standard dose of DDT (4 % DDT for 1 hour) in the laboratory was measured. From Curtis et al. (1978)." [figure: DDT-treated mosquito mortality goes down from 96% to 20% in 16 months] --- Indeed, in many countries, DDT was abandoned due to its ineffectiveness (mosquito resistance) rather than due to "Silent Spring"... > Meantime, we can have an academic discussion even as millions die in > the absence of the pesticide. As I mentioned before, window nets (such as the ones installed by a Swiss charity) are much more effective, and without poisoning the inhabitants. But the Gates foundation does NOT use window nets, because that wouldn't provide a RoI for the chemical industry for Gates, and it wouldn't serve the genocidal agenda. With "philanthropists" like that, who needs IG Farben?
