DDT

The latest folks to spread the DDT hoax are Kopel, Gallant and Eisen. They claim: [Malaria] is a disaster manufactured by First World political correctness; DDT prohibition is scientifically indefensible, and is responsible for millions of deaths every year. However, as explained in my posts on DDT, DDT is not banned from use against malaria, and while it is still helps against malaria in some places, it is not the panacea that Kopel et al make it out to be. They also write But rather than limiting DDT use, the United Nations is actively encouraging a worldwide ban on DDT.63 But reference…
Two more lazy and ignorant pundits have been spotted spreading the hoax about a non-existant DDT ban. In the New York Times Nicholas Kristof writes Environmentalists were right about DDT's threat to bald eagles, for example, but blocking all spraying in the third world has led to hundreds of thousands of malaria deaths. There is no ban on the the use of DDT against malaria. It is still used for that purpose. This fact is not a secret. Kristof just hasn't bothered to find out the truth. Writing in London's Daily Telegraph, Dick Taverne perpetrates this howler: DDT is another good example…
Ted Lapkin has objected to my reference to him in my post on the Great DDT Hoax. In his email he writes: I would very much prefer, if possible, to keep things on an informal basis rather than a legal one. Thus this whole misunderstanding can be cleared up by a retraction and apology on your blog. In that event I would see no need to pursue matters further. I offered to post his argument as to why he felt that I was wrong, but he declined, saying that it was a private communication. I have posted the paragraph above because I don't think threats are entitled to privacy…
Anti-environmentalist writers frequently claim that after DDT had all but eliminated malaria from Sri Lanka, environmentalist pressure forced Sri Lanka to ban DDT, leading to a resurgence of malaria: Roger Bate in Politicizing Science: The Alchemy of Policymaking writes: Some developing countries imposed a complete ban on the pesticide, as Sri Lanka did in 1964, when officials believed the malaria problem was solved. By 1969 the number of cases had risen from the low of seventeen (when DDT was used) to over a half million. Walter Williams in in…
Supporting sources for this post on the resurgence of malaria in Sri Lanka despite DDT spraying. From Malaria: Principles and Practice of Malariology edited by Wernsdorfer and McGregor (1988) Chapter 45 "The recent history of malaria control and eradication. by Gramiccia and Beales pages 1366-1367 In Sri Lanka, after the minimum of 17 cases in 1963, the incidence increased markedly and practically unimpeded, reaching 537 700 registered cases in 1969. There were still 400 700 cases in 1975. Malaria in Sri Lanka was known to produce epidemics at three to five year intervals…
In a recent post I observed that the Junk Central Station crew were ignorantly advocating the use of DDT in Sri Lanka after the tsunami, apparently unaware that mosquitoes in Sri Lanka were resistant to DDT. The World Health Organization's plan for malaria prevention in the wake of the tsunami advised against using DDT because: Sri Lanka Endemic sporadic malaria close to the affected areas transmitted by An.culicifacies, which has been considered DDT-resistant for many years, but is still sensitive to organophosphates, such as malathion, and pyrethroids. Conclusive,…
Following the tsunami, the folks at Junk Tech Fumento Central Science Station (JTFCSS) have been calling for DDT spraying. Here's Michael Fumento: The best answer would be spraying with DDT. Unfortunately, environmentalists have demonized DDT based essentially on unfounded accusations in a 1962 book, Silent Spring. ... DDT should be sprayed on water pools, tents, and on people themselves---as indeed was once common in Sri Lanka and throughout most of the world. And Tech Central Station: Imagine that every year the world suffered from six or…
