Experts in favour of tighter rules for DDT use against malaria

February 2, 2011 - 08:48 -- Guest (not verified)

UN-Experts on DDT recommend stricter rules when DDT is used for malaria vector control. Their report published ahead of the 5th Conference of the Parties to the Stockholm Convention (COP-5, Geneva April 25-29, 2011), shows more and more concern about effects of DDT on human health as well as on the environment. Their report was released last week, showing that the international community might be moving towards new rules on the use of DDT.

Open Access | Insecticide resistance in Anopheles arabiensis (Diptera: Culicidae) from villages in central, northern and south west Ethiopia and detection of kdr mutation

Since An. arabiensis shows high levels of resistance to DDT in all villages tested and varying pyrethroid resistance in Gorgora and the Ghibe River valley, precautionary measures should be taken in future vector control operations. Moreover, the status of resistance in other locations in Ethiopia and the spread of resistant gene (s) should be investigated.

'Mosquito: The fascinating world of public enemy number I' is out

November 27, 2009 - 11:22 -- Bart G.J. Knols

'Mug: De fascinerende wereld van volksvijand nummer I' went on sale in Dutch bookstores last Friday. The book (in Dutch) was written for the general public, to become familiarised with the difficulties of controlling diseases like malaria in developing countries. Given the absence of malaria in the Netherlands since 1959, the Dutch population has now lived for five decades without the threat of a mosquito-borne disease. There is therefore remarkably little general knowledge about mosquito-borne diseases, notably malaria.

Insecticide resistance and its association with target-site mutations in natural populations of Anopheles gambiae from eastern Uganda

Insecticide resistance in Anopheles gambiae threatens the success of malaria vector control programmes in sub-Saharan Africa. In order to manage insecticide resistance successfully, it is essential to assess continuously the target mosquito population. Here, we collected baseline information on the distribution and prevalence of insecticide resistance and its association with target-site mutations in eastern Uganda.

This study reports on the distribution of pyrethroid and DDT resistance and the L1014F knockdown resistance (kdr) mutation in Anopheles gambiae s.l. populations from 21 localities in three different climatic zones of Burkina Faso from August to October 2006. These results have practical significance for malaria vector control programs.
